released security updates for [iOS](<https://support.apple.com/en-us/HT212336>), [macOS](<https://support.apple.com/en-us/HT212335>), and [watchOS](<https://support.apple.com/en-us/HT212339>) to address three zero-day flaws and expand patches for a fourth vulnerability that the company said might have been exploited in the wild.\n\nThe weaknesses all concern WebKit, the browser engine which powers Safari and other third-party web browsers in iOS, allowing an adversary to execute arbitrary code on target devices. A summary of the three security bugs are as follows -\n\n * **CVE-2021-30663:** An integer overflow vulnerability that could be exploited to craft malicious web content, which may lead to code execution. The flaw was addressed with improved input validation.\n * **CVE-2021-30665:** A memory corruption issue that could be exploited to craft malicious web content, which may lead to code execution. The flaw was addressed with improved state management.\n * **CVE-2021-30666:** A buffer overflow vulnerability that could be exploited to craft malicious web content, which may lead to code execution. The flaw was addressed with improved memory handling.\n\nThe development comes a week after Apple rolled out iOS 14.5 and macOS Big Sur 11.3 with a fix for a potentially exploited WebKit Storage vulnerability. Tracked as [CVE-2021-30661](<https://thehackernews.com/2021/04/hackers-exploit-0-day-gatekeeper-flaw.html>), the use-after-free issue was discovered and reported to the iPhone maker by a security researcher named yangkang ([@dnpushme](<https://twitter.com/dnpushme>)) of Qihoo 360 ATA.\n\nyangkang, along with zerokeeper and bianliang, have been credited with reporting the three new flaws.\n\nIt's worth noting that CVE-2021-30666 only affects older Apple devices such as iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2, iPad mini 3, and iPod touch (6th generation). The [iOS 12.5.3](<https://support.apple.com/en-us/HT212341>) update, which remediates this flaw, also includes a fix for CVE-2021-30661.\n\nThe company said it's aware of reports that the issues \"may have been actively exploited\" but, as is typically the case, failed to elaborate about the nature of attacks, the victims that may have been targeted, or the threat actors that may be abusing them.\n\nUsers of Apple devices are recommended to update to the latest versions to mitigate the risk associated with the flaws.\n\n**Update: **Apple has also [released](<https://support.apple.com/en-us/HT212340>) a new version of Safari 14.1 for macOS Catalina and macOS Mojave, with the update introducing fixes for the two WebKit flaws CVE-2021-30663 and CVE-2021-30665. The update comes a day after patches were shipped for iOS, macOS, and watchOS.\n\n \n\n\nFound this article interesting?

As further proof of this, Apple released an update to macOS operating systems to address an actively exploited zero-day vulnerability that could circumvent all security protections, thus permitting unapproved software to run on Macs.\n\nThe macOS flaw, identified as [CVE-2021-30657](<https://support.apple.com/en-us/HT212325>), was discovered and reported to Apple by security engineer Cedric Owens on March 25, 2021.\n\n\"An unsigned, unnotarized, script-based proof of concept application [...] could trivially and reliably sidestep all of macOS's relevant security mechanisms (File Quarantine, Gatekeeper, and Notarization Requirements), even on a fully patched M1 macOS system,\" security researcher Patrick Wardle [explained](<https://objective-see.com/blog/blog_0x64.html>) in a write-up. \"Armed with such a capability macOS malware authors could (and are) returning to their proven methods of targeting and infecting macOS users.\"\n\nApple's macOS comes with a feature called [Gatekeeper](<https://support.apple.com/guide/deployment-reference-macos/using-gatekeeper-apd02b925e38/web>), which allows only [trusted apps](<https://support.apple.com/en-us/HT202491>) to be run by ensuring that the software has been signed by the App Store or by a registered developer and has cleared an automated process called \"[app notarization](<https://developer.apple.com/documentation/xcode/notarizing_macos_software_before_distribution>)\" that scans the software for malicious content.\n\nBut the new flaw uncovered by Owens could enable an adversary to craft a rogue application in a manner that would deceive the Gatekeeper service and get executed without triggering any security warning. The trickery involves packaging a malicious shell script as a \"double-clickable app\" so that the malware could be double-clicked and run like an app.\n\n\"It's an app in the sense that you can double click it and macOS views it as an app when you right click -> Get Info on the payload,\" Owens [said](<https://cedowens.medium.com/macos-gatekeeper-bypass-2021-edition-5256a2955508>). \"Yet it's also shell script in that shell scripts are not checked by Gatekeeper even if the [quarantine](<https://www.trendmicro.com/en_us/research/20/k/new-macos-backdoor-connected-to-oceanlotus-surfaces.html>) attribute is present.\"\n\n[](<https://thehackernews.com/images/-VJcAfeigXAU/YIflxqbcR8I/AAAAAAAACYQ/2BXHadqOI30gqgbTdpezN6aBLvMI51aJgCLcBGAsYHQ/s0/malware.jpg>)\n\n[](<https://thehackernews.com/images/-5-2DSx3g1lM/YIflwyqs9yI/AAAAAAAACYM/2zPv2m4h6H0XzaEyV_bxo63N0O1goK4BACLcBGAsYHQ/s0/macos-malware.jpg>)\n\nAccording to macOS security firm [Jamf](<https://www.jamf.com/blog/shlayer-malware-abusing-gatekeeper-bypass-on-macos/>), the threat actor behind [Shlayer](<https://www.intego.com/mac-security-blog/osxshlayer-new-mac-malware-comes-out-of-its-shell/>) malware has been abusing this Gatekeeper bypass vulnerability as early as January 9, 2021. Distributed via a technique called search engine poisoning or spamdexing, Shlayer accounts for almost 30% of all detections on the macOS platform, with one in ten systems encountering the adware at least once, according to [Kaspersky](<https://securelist.com/shlayer-for-macos/95724/>) statistics for 2019.\n\nThe attack works by manipulating search engine results to surface malicious links that, when clicked, redirects users to a web page that prompts users to download a seemingly benign app update for out-of-date software, which in this campaign, is a bash script designed to retrieve next-stage payloads, including Bundlore adware stealthily. Troublingly, this infection scheme could be leveraged to deliver more advanced threats such as surveillanceware and ransomware.\n\nIn addition to the aforementioned vulnerability, Monday's updates also address a critical flaw in WebKit Storage (tracked as CVE-2021-30661) that concerns an arbitrary code execution flaw in [iOS](<https://support.apple.com/en-us/HT212317>), [macOS](<https://support.apple.com/en-us/HT212325>), [tvOS](<https://support.apple.com/en-us/HT212323>), and [watchOS](<https://support.apple.com/en-us/HT212324>) when processing maliciously crafted web content.\n\n\"Apple is aware of a report that this issue may have been actively exploited,\" the company said in a security document, adding it addressed the use-after-free weakness with improved memory management.\n\nAside from these updates, Apple has also released [iCloud for Windows 12.3](<https://support.apple.com/en-us/HT212321>) with patches for four security issues in WebKit and WebRTC, among others, that could allow an attacker to cross-site scripting (XSS) attacks (CVE-2021-1825) and corrupt kernel memory (CVE-2020-7463).\n\nUsers of Apple devices are recommended to update to the latest versions to mitigate the risk associated with the flaws.\n\n \n\n\nFound this article interesting?

The flaw was addressed with improved state management.\n * **CVE-2021-30762** \\- A use-after-free issue that could be exploited to gain arbitrary code execution when processing maliciously crafted web content. The flaw was resolved with improved memory management.\n\nBoth CVE-2021-30761 and CVE-2021-30762 were reported to Apple anonymously, with the Cupertino-based company stating in its advisory that it's aware of reports that the vulnerabilities \"may have been actively exploited.\" As is usually the case, Apple didn't share any specifics on the nature of the attacks, the victims that may have been targeted, or the threat actors that may be abusing them.\n\nOne thing evident, however, is that the active exploitation attempts were directed against owners of older devices such as iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2, iPad mini 3, and iPod touch (6th generation). The move mirrors a similar fix that Apple rolled out on May 3 to remediate a buffer overflow vulnerability (CVE-2021-30666) in WebKit targeting the same set of devices.\n\nAlong with the two aforementioned flaws, Apple has patched a total of 12 zero-days affecting iOS, iPadOS, macOS, tvOS, and watchOS since the start of the year \u2014\n\n * [**CVE-2021-1782**](<https://thehackernews.com/2021/01/apple-warns-of-3-ios-zero-day-security.html>) (Kernel) - A malicious application may be able to elevate privileges\n * [**CVE-2021-1870**](<https://thehackernews.com/2021/01/apple-warns-of-3-ios-zero-day-security.html>) (WebKit) - A remote attacker may be able to cause arbitrary code execution\n * [**CVE-2021-1871**](<https://thehackernews.com/2021/01/apple-warns-of-3-ios-zero-day-security.html>) (WebKit) - A remote attacker may be able to cause arbitrary code execution\n * [**CVE-2021-1879**](<https://thehackernews.com/2021/03/apple-issues-urgent-patch-update-for.html>) (WebKit) - Processing maliciously crafted web content may lead to universal cross-site scripting\n * [**CVE-2021-30657**](<https://thehackernews.com/2021/04/hackers-exploit-0-day-gatekeeper-flaw.html>) (System Preferences) - A malicious application may bypass Gatekeeper checks\n * [**CVE-2021-30661**](<https://thehackernews.com/2021/04/hackers-exploit-0-day-gatekeeper-flaw.html>) (WebKit Storage) - Processing maliciously crafted web content may lead to arbitrary code execution\n * [**CVE-2021-30663**](<https://thehackernews.com/2021/05/apple-releases-urgent-security-patches.html>) (WebKit) - Processing maliciously crafted web content may lead to arbitrary code execution\n * [**CVE-2021-30665**](<https://thehackernews.com/2021/05/apple-releases-urgent-security-patches.html>) (WebKit) - Processing maliciously crafted web content may lead to arbitrary code execution\n * [**CVE-2021-30666**](<https://thehackernews.com/2021/05/apple-releases-urgent-security-patches.html>) (WebKit) - Processing maliciously crafted web content may lead to arbitrary code execution\n * [**CVE-2021-30713**](<https://thehackernews.com/2021/05/apple-issues-patches-to-combat-ongoing.html>) (TCC framework) - A malicious application may be able to bypass Privacy preferences\n\nUsers of Apple devices are recommended to update to the latest versions to mitigate the risk associated with the vulnerabilities.\n\n \n\n\nFound this article interesting?

Apple credited an anonymous researcher for discovering and reporting the vulnerability.\n\nThe timing of the update also raises questions about whether the zero-day had any role in compromising iPhones using NSO Group's [Pegasus software](<https://forbiddenstories.org/case/the-pegasus-project/>), which has become the focus of a series of [investigative reports](<https://thehackernews.com/2021/07/new-leak-reveals-abuse-of-pegasus.html>) that have exposed how the spyware tool turned mobile phones of journalists, human rights activists, and others into portable surveillance devices, granting complete access to sensitive information stored in them.\n\nCVE-2021-30807 is also the thirteenth zero-day vulnerability addressed by Apple this year alone, including \u2014\n\n * [CVE-2021-1782](<https://thehackernews.com/2021/01/apple-warns-of-3-ios-zero-day-security.html>) (Kernel) - A malicious application may be able to elevate privileges\n * [CVE-2021-1870](<https://thehackernews.com/2021/01/apple-warns-of-3-ios-zero-day-security.html>) (WebKit) - A remote attacker may be able to cause arbitrary code execution\n * [CVE-2021-1871](<https://thehackernews.com/2021/01/apple-warns-of-3-ios-zero-day-security.html>) (WebKit) - A remote attacker may be able to cause arbitrary code execution\n * [CVE-2021-1879](<https://thehackernews.com/2021/03/apple-issues-urgent-patch-update-for.html>) (WebKit) - Processing maliciously crafted web content may lead to universal cross-site scripting\n * [CVE-2021-30657](<https://thehackernews.com/2021/04/hackers-exploit-0-day-gatekeeper-flaw.html>) (System Preferences) - A malicious application may bypass Gatekeeper checks\n * [CVE-2021-30661](<https://thehackernews.com/2021/04/hackers-exploit-0-day-gatekeeper-flaw.html>) (WebKit Storage) - Processing maliciously crafted web content may lead to arbitrary code execution\n * [CVE-2021-30663](<https://thehackernews.com/2021/05/apple-releases-urgent-security-patches.html>) (WebKit) - Processing maliciously crafted web content may lead to arbitrary code execution\n * [CVE-2021-30665](<https://thehackernews.com/2021/05/apple-releases-urgent-security-patches.html>) (WebKit) - Processing maliciously crafted web content may lead to arbitrary code execution\n * [CVE-2021-30666](<https://thehackernews.com/2021/05/apple-releases-urgent-security-patches.html>) (WebKit) - Processing maliciously crafted web content may lead to arbitrary code execution\n * [CVE-2021-30713](<https://thehackernews.com/2021/05/apple-issues-patches-to-combat-ongoing.html>) (TCC framework) - A malicious application may be able to bypass Privacy preferences\n * [CVE-2021-30761](<https://thehackernews.com/2021/06/apple-issues-urgent-patches-for-2-zero.html>) (WebKit) - Processing maliciously crafted web content may lead to arbitrary code execution\n * [CVE-2021-30762](<https://thehackernews.com/2021/06/apple-issues-urgent-patches-for-2-zero.html>) (WebKit) - Processing maliciously crafted web content may lead to arbitrary code execution\n\nGiven the [public availability](<https://twitter.com/b1n4r1b01/status/1419734027565617165>) of a proof-of-concept (PoC) exploit, it's highly recommended that users move quickly to update their devices to the latest version to mitigate the risk associated with the flaw.\n\n \n\n\nFound this article interesting?

Crediting an anonymous researcher for reporting the vulnerability, Apple said it's \"aware of a report that this issue may have been actively exploited.\"\n\nTechnical specifics about the flaw and the nature of the attacks remain unavailable as yet, as is the identity of the threat actor, so as to allow a majority of the users to apply the patch and prevent other adversaries from weaponizing the vulnerability. The iPhone maker said it addressed the issue with improved memory handling.\n\nBut soon after the advisory was released, security researcher Saar Amar [shared](<https://saaramar.github.io/IOMFB_integer_overflow_poc/>) additional details, and a proof-of-concept (PoC) exploit, noting that \"this attack surface is highly interesting because it's accessible from the app sandbox (so it's great for jailbreaks) and many other processes, making it a good candidate for LPEs exploits in chains.\"\n\nCVE-2021-30883 is also the second zero-day impacting IOMobileFrameBuffer after Apple addressed a similar, anonymously reported memory corruption issue (CVE-2021-30807) in July 2021, raising the possibility that the two flaws could be related.

Here\u2019s a summary of the three zero-days: \n\n## **Zero-Day Bugs in WebKit**\n\n * **CVE-2021-30665:** A critical memory-corruption issue in the Safari WebKit engine where \u201cprocessing maliciously crafted web content may lead to arbitrary code execution\u201d was addressed with improved state management. Available for: iPhone 6s and later, iPad Pro (all models), iPad Air 2 and later, iPad 5th generation and later, iPad mini 4 and later, and iPod touch (7th generation). The bug was reported to Apple by three security researchers, nicknamed yangkang, zerokeeper and bianliang. \n\n * **CVE-2021-30663:** This second flaw is also found in the open-source WebKit browser engine. It\u2019s an integer overflow, reported by an anonymous researcher, that can also lead to RCE. It was addressed with improved input validation. Available for: iPhone 6s and later, iPad Pro (all models), iPad Air 2 and later, iPad 5th generation and later, iPad mini 4 and later, and iPod touch (7th generation). \n\n * **CVE-2021-30666:** A buffer-overflow issue was addressed with improved memory handling. Available for: iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2, iPad mini 3, and iPod touch (6th generation)\n\nAnd here are details on the expanded patch for the fourth bug: \n\n## **WebKit Storage**\n\n * **CVE-2021-30661: **A use after free issue was addressed with improved memory management. Available for: iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2, iPad mini 3, and iPod touch (6th generation). This flaw was discovered and reported to the iPhone maker by the security researcher named yangkang, @dnpushme, of Qihoo 360 ATA.\n\nApple\u2019s support page shows that this fourth one was actually patched on Monday last week (April 26) in iOS 14.5 and macOS 11.3, but not in iOS 12. \n\nNaked Security\u2019s Paul Ducklin finds this one [particularly interesting](<https://nakedsecurity.sophos.com/2021/05/04/apple-products-hit-by-fourfecta-of-zero-day-exploits-patch-now/>), and he noted that questions remain. Why wasn\u2019t iOS 12 updated at the same time as iOS 14.5 and macOS 11.3? Did the security hole crop up in the code base after iOS 12 was released, perhaps? \n\nNo, that\u2019s not it: the CVE-2021-30661 and CVE-2021-30666 bugs fixed on Monday only apply to iOS 12. So it remains unclear if the bug exists in recent operating system versions, or not, Ducklin said.\n\n\u201cIs this an old bug from iOS 12 that was carried forward into the current Apple codebase but has still not yet been patched there?\u201d Ducklin pondered. \u201cOr is it a bug that is unique to the older iOS 12 code that doesn\u2019t appear in the more recent operating system releases and can therefore now be considered to have been eliminated everywhere?\u201d\n\nThreatpost has reached out to Apple for comment.\n\n## **Patch Fast!**\n\nPer usual, Apple\u2019s lip is zipped. But one thing\u2019s for sure: Patching as soon as possible is top priority. As it is, the chance for websites passing along \u201cmaliciously crafted web content\u201d is alarming. If you translate Apple\u2019s statement that \u201cprocessing maliciously crafted web content may lead to arbitrary code execution, \u201cyou get a \u201c[drive-by](<https://threatpost.com/google-sites-solarmarket-rat/165396/>), web-based zero-day RCE exploit, according to Ducklin.\n\nIn other words, all you have to do to trigger infection is to visit and view a booby-trapped website. \n\nJohn Kinsella, chief architect at cloud security company Accurics, says this is one of the nastier types of security bugs: one in which the user isn\u2019t required to perform a certain action for an attacker\u2019s success. \u201cPart of the issue here is that it\u2019s not just the browser that a user needs to be careful with,\u201d he told Threatpost in an email on Tuesday. \u201cMany iOS apps are just wrappers around a web application, which would be rendered by WebKit. For example, HTML mail in Apple\u2019s Mail app will be rendered by WebKit, and this app is a hard one to avoid. Even if a user takes advantage of new iOS functionality to replace the default iOS Mail and Safari apps with other mail/browser apps, the underlying HTML rendering engine would still be WebKit-based on Apple\u2019s App Store rules.\u201d\n\nKinsella says that if he\u2019s at all suspicious of something, he won\u2019t open it on a mobile device, but rather on a desktop or laptop, where he has much more control. \u201cThat being said, I know I\u2019m not the average user,\u201d he said. \u201cThe best advice I have is to patch ASAP, and generally be very careful.\u201d\n\nGiven that Apple has acknowledged that these vulnerabilities have already been exploited in the wild, and given the fact that HTML content is so prevalent on mobile devices, Kinsella considers a drive-by RCE like this to be a highly serious issue, though \u201cThe overall security of iOS means this isn\u2019t a complete takeover of the mobile device.\u201d\n\nStill, every extra foothold an attacker can get \u201chelps them further compromise a device,\u201d he said. \u201cThe fact that malicious HTML can compromise something on my wrist doesn\u2019t thrill me. Luckily Apple\u2019s been quite consistent with the reliability of their patches in recent years, so while I may sometimes wait for others to \u2018beta test\u2019 a release, a security patch like this was applied to my devices ASAP.\u201d\n\n## **What is WebKit? The Little Engine That Could**\n\nApple developed the WebKit browser engine to run in its Safari web browser, but it\u2019s also used by Apple Mail, the App Store, and various apps on the macOS and iOS operating systems. This, of course, isn\u2019t the first time that the engine has hit some bumps. \n\nIn January, Apple released an emergency update that patched three iOS[ bugs](<https://threatpost.com/apple-patches-zero-days-ios-emergency-update/163374/>). Two of them (CVE-2021-1870 and CVE-2021-1871 ) were discovered in WebKit (and the third, tracked as CVE-2021-1782, was found in the OS kernel).\n\nMore recently, in March, Apple patched other [severe WebKit RCEs](<https://threatpost.com/apple-webkit-remote-code-execution/164595/>). Similar to Monday\u2019s updates, those WebKit fixes could have allowed remote attackers to completely compromise affected systems.\n\n05-04-2021 14:52 UPDATE: Added input from Accurics\u2019 John Kinsella.\n\n**Join Threatpost for \u201c**[**Fortifying Your Business Against Ransomware, DDoS & Cryptojacking Attacks**](<https://threatpost.com/webinars/fortifying-your-business-against-attacks/?utm_source=ART&utm_medium=ART&utm_campaign=May_Zoho_Webinar>)**\u201d \u2013 a LIVE roundtable event on**[** Wed, May 12 at 2:00 PM EDT**](<https://threatpost.com/webinars/fortifying-your-business-against-attacks/?utm_source=ART&utm_medium=ART&utm_campaign=May_Zoho_Webinarhttps://threatpost.com/webinars/fortifying-your-business-against-attacks/?utm_source=ART&utm_medium=ART&utm_campaign=May_Zoho_Webinar>)**.

It has been said that a [leaked list of 50,000](<https://techcrunch.com/2021/07/19/toolkit-nso-pegasus-iphone-android/>) phone numbers of potential surveillance targets was obtained by Paris-based journalism nonprofit Forbidden Stories and Amnesty International.\n\nPegasus spyware is a surveillance software created by Israeli cyber intelligence firm NSO Group. Pegasus is one such software developed to gain access to your phone without consent and gather personal and sensitive information and deliver it to the user spying on you.\n\n### Attack Vectors and Impact of Pegasus Spyware\n\nThe first version of the spyware was detected in 2016 and used spear-phishing to infect a smartphone. It now adopts a different and more sophisticated approach for reaching new targets. It can infect a device using the "[zero-click](<https://www.aljazeera.com/news/2020/12/21/al-jazeera-journalists-hacked-by-spyware-sold-by-israeli-firm>)" attack done by exploiting the vulnerabilities present on the victim device. The "zero-click" attack happened earlier in December 2020 using iMessage vulnerabilities. Also, in [2019](<https://www.ft.com/content/4da1117e-756c-11e9-be7d-6d846537acab>) using the WhatsApp vulnerabilities.\n\nThe attack vectors for the Pegasus spyware are the vulnerabilities present on the devices: OS-level message (SMS) or iMessage app, WhatsApp, or other vulnerabilities that can be exploited.\n\nOnce Pegasus spyware is installed on the device, it can effectively monitor any activity you perform on it. This includes reading or copying your messages, extracting your media files, accessing your browser history, recording your calls, and much more.\n\n\n\n### VMDR for Mobile Devices Helps Protect from Pegasus Spyware\n\n[Qualys VMDR for Mobile Devices](<https://www.qualys.com/apps/vulnerability-management-detection-response/mobile-devices/>) detects devices that are potentially prone to Pegasus spyware based on the vulnerabilities mentioned below, which is a proactive approach. Pegasus is sophisticated spyware with anti-forensic and self-destruct features that make it difficult to detect. If it is uninstalled later, it does not leave any trace. VMDR for Mobile Devices must therefore detect if the device is vulnerable to Pegasus rather than detecting the presence of Pegasus spyware itself.\n\n#### iOS Pegasus:\n\nAll iOS devices are vulnerable to the following CVEs that are fixed in the latest iOS versions that might be used to install Pegasus spyware and to get the details from the devices\n\n * CVE-2020-9954, CVE-2020-9956, CVE-2020-9947, CVE-2020-9950, CVE-2020-9988, CVE-2020-9989, CVE-2020-9941 \u2013 Fixed in iOS and iPadOS 14\n * CVE-2020-10017, CVE-2020-27908, CVE-2020-27909 \u2013 Fixed in iOS and iPadOS 14.2\n * CVE-2020-29610 \u2013 Fixed in iOS and iPadOS 14.3\n * CVE-2021-1838, CVE-2021-1746, CVE-2021-1743, CVE-2021-1763, CVE-2021-1768, CVE-2021-1745, CVE-2021-1762, CVE-2021-1767, CVE-2021-1753, CVE-2021-1781 \u2013 Fixed in iOS 14.4\n * CVE-2021-1879 \u2013 Fixed in iOS and iPadOS 14.4.2\n * CVE-2021-30743, CVE-2021-1883 \u2013 Fixed in iOS 14.5\n * CVE-2021-30665, CVE-2021-30663, CVE-2021-30666(iOS 12.5.3), CVE-2021-30661(iOS 12.5.3) \u2013 Fixed in iOS and iPadOS 14.5.1 & iOS 12.5.3\n * CVE-2021-30707, CVE-2021-30749, CVE-2021-30734 \u2013 Fixed in iOS and iPadOS 14.6\n * CVE-2021-30788, CVE-2021-30759, CVE-2021-30792, CVE-2021-30791 \u2013 Fixed in iOS and iPadOS 14.7\n\n_Note that more CVEs might be exploited by Pegasus of the old iOS versions, i.e., below 14.0. If you are using old iOS versions, then your device might be more vulnerable to Pegasus spyware._\n\nWith VMDR for Mobile Devices, quickly check the security posture of all your mobile devices across your enterprise to remove blind spots, continuously detect these vulnerabilities and prioritize them. This helps you to take appropriate actions on the impacted devices.\n\n \n\n#### Android Pegasus:\n\nVMDR for Mobile Devices quickly detects and prioritizes all the WhatsApp vulnerabilities, other messaging app vulnerabilities, and OS vulnerabilities. Earlier, the attack of Pegasus was made through [WhatsApp](<https://www.whatsapp.com/security/advisories/2021/>) app vulnerabilities, i.e., the Pegasus spyware can be installed on the phone using these vulnerabilities.\n\n\n\n#### Respond by Patching and Remediation\n\nVMDR for Mobile Devices helps you to get a view of all vulnerabilities along with their priorities. Prioritizing the vulnerabilities based on the severity helps you take corrective and preventive actions on the impacted devices.\n\nVMDR for Mobile Devices provides you the patch orchestration for Android devices that helps you rapidly remediate your Android assets. Patch orchestration helps you initiate the most relevant per-application version patches on the affected assets.\n\nYou do not have to create multiple jobs; one job will take care of all vulnerabilities of that application.\n\n\n\nVMDR for Mobile Devices will also detect the app installed from an unknown source and its configurations (available by the end of August). The Pegasus may be introduced or installed through an unknown source in Android and ask the user for the required permission to monitor activities.\n\n\n\nIn addition, VMDR for Mobile Devices detects all vulnerabilities of Android and iOS OS vulnerabilities fixed by Apple and Google in their security updates. These vulnerabilities lead Pegasus spyware to take control of the device.\n\nKeep an eye on the vulnerabilities detected by VMDR for Mobile Devices and take appropriate actions. That will help you to secure the devices from Pegasus spyware because the spyware can be installed only if the vulnerabilities are present on the device.\n\nAlso, if the devices are jailbroken or rooted, track them through the \u201cUnauthorized Root Access\u201d widget or use QQL (Qualys Query Language) \u2013 \u201casset.hasUnauthorizedRootAccess: Yes\u201d to find the compromised devices.\n\n\n\n### Get Started Now\n\n[Qualys VMDR for Mobile Devices](<https://www.qualys.com/apps/vulnerability-management-detection-response/mobile-devices/>) is available free for 30 days to help customers detect vulnerabilities, monitor critical device settings, and correlate updates with the correct app versions available on Google Play Store.

[This directive](<https://www.cisa.gov/news/2021/11/03/cisa-releases-directive-reducing-significant-risk-known-exploited-vulnerabilities>) recommends urgent and prioritized remediation of the vulnerabilities that adversaries are actively exploiting. It establishes a CISA-managed catalog of known exploited vulnerabilities that carry significant risk to the federal government and establishes requirements for agencies to remediate these vulnerabilities.\n\nThis directive requires agencies to review and update agency internal vulnerability management procedures within 60 days according to this directive and remediate each vulnerability according to the timelines outlined in 'CISA's vulnerability catalog.\n\nQualys helps customers to identify and assess risk to organizations' digital infrastructure and automate remediation. Qualys' guidance for rapid response to Operational Directive is below.\n\n## Directive Scope\n\nThis directive applies to all software and hardware found on federal information systems managed on agency premises or hosted by third parties on an agency's behalf.\n\nHowever, CISA strongly recommends that private businesses and state, local, tribal, and territorial (SLTT) governments prioritize the mitigation of vulnerabilities listed in CISA's public catalog.\n\n## CISA Catalog of Known Exploited Vulnerabilities\n\nIn total, CISA posted a list of [291 Common Vulnerabilities and Exposures (CVEs)](<https://www.cisa.gov/known-exploited-vulnerabilities-catalog>) that pose the highest risk to federal agencies. The Qualys Research team has mapped all these CVEs to applicable QIDs. You can view the complete list of CVEs and the corresponding QIDs [here](<https://success.qualys.com/discussions/s/article/000006791>).\n\n### Not all vulnerabilities are created equal\n\nOur quick review of the 291 CVEs posted by CISA suggests that not all vulnerabilities hold the same priority. CISA has ordered U.S. federal enterprises to apply patches as soon as possible. The remediation guidance can be grouped into three distinct categories:\n\n#### Category 1 \u2013 Past Due\n\nRemediation of 15 CVEs (~5%) are already past due. These vulnerabilities include some of the most significant exploits in the recent past, including PrintNightmare, SigRed, ZeroLogon, and vulnerabilities in CryptoAPI, Pulse Secure, and more. Qualys Patch Management can help you remediate most of these vulnerabilities.\n\n#### Category 2 \u2013 Patch in less than two weeks\n\n100 (34%) Vulnerabilities need to be patched in the next two weeks, or by **November 17, 2022**.\n\n#### Category 3 \u2013 Patch within six months\n\nThe remaining 176 vulnerabilities (60%) must be patched within the next six months or by **May 3, 2022**.\n\n## Detect CISA's Vulnerabilities Using Qualys VMDR\n\nThe Qualys Research team has released several remote and authenticated detections (QIDs) for the vulnerabilities. Since the directive includes 291 CVEs, we recommend executing your search based on vulnerability criticality, release date, or other categories.\n\nFor example, to detect critical CVEs released in 2021:\n\n_vulnerabilities.vulnerability.criticality:CRITICAL and vulnerabilities.vulnerability.cveIds:[ `CVE-2021-1497`,`CVE-2021-1498`,`CVE-2021-1647`,`CVE-2021-1675`,`CVE-2021-1732`,`CVE-2021-1782`,`CVE-2021-1870`,`CVE-2021-1871`,`CVE-2021-1879`,`CVE-2021-1905`,`CVE-2021-1906`,`CVE-2021-20016`,`CVE-2021-21017`,`CVE-2021-21148`,`CVE-2021-21166`,`CVE-2021-21193`,`CVE-2021-21206`,`CVE-2021-21220`,`CVE-2021-21224`,`CVE-2021-21972`,`CVE-2021-21985`,`CVE-2021-22005`,`CVE-2021-22205`,`CVE-2021-22502`,`CVE-2021-22893`,`CVE-2021-22894`,`CVE-2021-22899`,`CVE-2021-22900`,`CVE-2021-22986`,`CVE-2021-26084`,`CVE-2021-26411`,`CVE-2021-26855`,`CVE-2021-26857`,`CVE-2021-26858`,`CVE-2021-27059`,`CVE-2021-27065`,`CVE-2021-27085`,`CVE-2021-27101`,`CVE-2021-27102`,`CVE-2021-27103`,`CVE-2021-27104`,`CVE-2021-28310`,`CVE-2021-28550`,`CVE-2021-28663`,`CVE-2021-28664`,`CVE-2021-30116`,`CVE-2021-30551`,`CVE-2021-30554`,`CVE-2021-30563`,`CVE-2021-30632`,`CVE-2021-30633`,`CVE-2021-30657`,`CVE-2021-30661`,`CVE-2021-30663`,`CVE-2021-30665`,`CVE-2021-30666`,`CVE-2021-30713`,`CVE-2021-30761`,`CVE-2021-30762`,`CVE-2021-30807`,`CVE-2021-30858`,`CVE-2021-30860`,`CVE-2021-30860`,`CVE-2021-30869`,`CVE-2021-31199`,`CVE-2021-31201`,`CVE-2021-31207`,`CVE-2021-31955`,`CVE-2021-31956`,`CVE-2021-31979`,`CVE-2021-33739`,`CVE-2021-33742`,`CVE-2021-33771`,`CVE-2021-34448`,`CVE-2021-34473`,`CVE-2021-34523`,`CVE-2021-34527`,`CVE-2021-35211`,`CVE-2021-36741`,`CVE-2021-36742`,`CVE-2021-36942`,`CVE-2021-36948`,`CVE-2021-36955`,`CVE-2021-37973`,`CVE-2021-37975`,`CVE-2021-37976`,`CVE-2021-38000`,`CVE-2021-38003`,`CVE-2021-38645`,`CVE-2021-38647`,`CVE-2021-38647`,`CVE-2021-38648`,`CVE-2021-38649`,`CVE-2021-40444`,`CVE-2021-40539`,`CVE-2021-41773`,`CVE-2021-42013`,`CVE-2021-42258` ]_\n\n\n\nUsing [Qualys VMDR](<https://www.qualys.com/subscriptions/vmdr/>), you can effectively prioritize those vulnerabilities using the VMDR Prioritization report.\n\n\n\nIn addition, you can locate a vulnerable host through Qualys Threat Protection by simply clicking on the impacted hosts to effectively identify and track this vulnerability.\n\n\n\nWith Qualys Unified Dashboard, you can track your exposure to the CISA Known Exploited Vulnerabilities and gather your status and overall management in real-time.

Its goal is to make it easier to share data across separate vulnerability capabilities (tools, databases, and services). This one is listed as [CVE-2021-30883](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-30883>) and allows an application to execute arbitrary code with kernel privileges. Kernel privileges can be achieved by using a memory corruption issue in the "IOMobileFrameBuffer" component.\n\nKernel privileges are a serious matter as they offer an attacker more than administrator privileges. In kernel mode, the executing code has complete and unrestricted access to the underlying hardware. It can execute any CPU instruction and reference any memory address. Kernel mode is generally reserved for the lowest-level, most trusted functions of the operating system.\n\nResearchers have already found that this vulnerability is exploitable from the browser, which makes it extra worrying.\n\n> We can confirm that the recently patched iOS 15.0.2 vulnerability, CVE-2021-30883, is also accessible from the browser: perfect for 1-click & water-holing mobile attacks. This vulnerability is exploited in the wild. Update as soon as possible. <https://t.co/dhogxTM6pT>\n> \n> -- ZecOps (@ZecOps) [October 12, 2021](<https://twitter.com/ZecOps/status/1447804721771606016?ref_src=twsrc%5Etfw>)\n\nWatering holes are used as a highly targeted attack strategy. The attacker infects a website where they knows the intended victim(s) visits regularly. Depending on the nature of the infection, the attacker can single out their intended target(s) or just infect anyone that visits the site unprotected.\n\n### IOMobileFrameBuffer\n\nIOMobileFramebuffer is a kernel extension for managing the screen framebuffer. An earlier vulnerability in this extension, listed as [CVE-2021-30807](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-30807>) was tied to the [Pegasus spyware](<https://blog.malwarebytes.com/privacy-2/2021/07/pegasus-spyware-has-been-here-for-years-we-must-stop-ignoring-it/>). This vulnerability also allowed an application to execute arbitrary code with kernel privileges. Coincidence? Or did someone take the entire IOMobileFramebuffer extension apart and save up the vulnerabilities for a rainy day?\n\nAnother iPhone exploit called [FORCEDENTRY](<https://blog.malwarebytes.com/exploits-and-vulnerabilities/2021/08/latest-iphone-exploit-forcedenrty-used-to-launch-pegasus-attack-against-bahraini-activists/>) was found to be used against Bahraini activists to launch the Pegasus spyware. Researchers at Citizen Lab disclosed this vulnerability and code to Apple, and it was listed as CVE-2021-30860.\n\n### Undisclosed\n\nAs is usual for Apple, both the researcher that found the vulnerability and the circumstances under which the vulnerability used in the wild are kept secret. Apple didn't respond to a query about whether the previously found bug was being exploited by NSO Group's Pegasus surveillance software.\n\n### Zero-days for days\n\nOver the last months Apple has had to close quite a few zero-days in iOS, iPadOS,and macOS. Seventeen if I have counted correctly.\n\n * [CVE-2021-1782](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-1782>) - iOS-kernel: A malicious application may be able to elevate privileges.

Perhaps the most notable event of the quarter was the [attack by the DarkSide group on Colonial Pipeline](<https://ics-cert.kaspersky.com/reports/2021/05/21/darkchronicles-the-consequences-of-the-colonial-pipeline-attack/>), one of the largest fuel pipeline operators in the US. The incident led to fuel outages and a state of emergency in four states. The results of the investigation, which involved the FBI and several other US government agencies, was reported to US President Joe Biden.\n\nFor the cybercriminals, this sudden notoriety proved unwelcome. In their blog, DarkSide's creators heaped the blame on third-party operators. Another post was published stating that DarkSide's developers had lost access to part of their infrastructure and were shutting down the service and the affiliate program.\n\nAnother consequence of this high-profile incident was a new rule on the Russian-language forum XSS, where many developers of ransomware, including REvil (also known as Sodinokibi or Sodin), LockBit and Netwalker, advertise their affiliate programs. The new rule forbade the advertising and selling of any ransomware programs on the site. The administrators of other forums popular with cybercriminals took similar decisions.\n\n#### Closure of Avaddon\n\nAnother family of targeted ransomware whose owners shut up shop in Q2 is Avaddon.

In particular, the share of exploits for Microsoft Office dropped to 55.81% of the total number of threats of this type. Conversely, the share of exploits attacking popular browsers rose by roughly 3 p.p. to 29.13%.\n\n_Distribution of exploits used by cybercriminals, by type of attacked application, Q2 2021 ([download](<https://media.kasperskycontenthub.com/wp-content/uploads/sites/43/2021/08/11141656/09-en-malware-report-q2-2021-graphs-pc.png>))_\n\nMicrosoft Office exploits most often tried to utilize the memory corruption vulnerability [CVE-2018-0802](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-0802>). This error can occur in the Equation Editor component when processing objects in a specially constructed document, and its exploitation causes a buffer overflow and allows an attacker to execute arbitrary code. Also seen in Q2 was the similar vulnerability [CVE-2017-11882](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2017-11882>), which causes a buffer overflow on the stack in the same component. Lastly, we spotted an attempt to exploit the [CVE-2017-8570](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2017-8570>) vulnerability, which, like other bugs in Microsoft Office, permits the execution of arbitrary code in vulnerable versions of the software.\n\nQ2 2021 was marked by the emergence of several dangerous vulnerabilities in various versions of the Microsoft Windows family, many of them observed in the wild. Kaspersky alone found three vulnerabilities used in targeted attacks:\n\n * [CVE-2021-28310](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-28310>) \u2014 an out-of-bounds (OOB) write vulnerability in the Microsoft DWM Core library used in Desktop Window Manager. Due to insufficient checks in the data array code, an unprivileged user using the DirectComposition API can write their own data to the memory areas they control. As a result, the data of real objects is corrupted, which, in turn, can lead to the execution of arbitrary code;\n * [CVE-2021-31955](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-31955>) \u2014 an information disclosure vulnerability that exposes information about kernel objects. Together with other exploits, it allows an intruder to attack a vulnerable system;\n * [CVE-2021-31956](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-31956>) \u2014 a vulnerability in the ntfs.sys file system driver. It causes incorrect checking of transferred sizes, allowing an attacker to inflict a buffer overflow by manipulating parameters.\n\nYou can read more about these vulnerabilities and their exploitation in our articles [PuzzleMaker attacks with Chrome zero-day exploit chain](<https://securelist.com/puzzlemaker-chrome-zero-day-exploit-chain/102771/>) and [Zero-day vulnerability in Desktop Window Manager (CVE-2021-28310) used in the wild](<https://securelist.com/zero-day-vulnerability-in-desktop-window-manager-cve-2021-28310-used-in-the-wild/101898/>).\n\nOther security researchers found a number of browser vulnerabilities, including:\n\n * [CVE-2021-33742](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-33742>) \u2014 a bug in the Microsoft Trident browser engine (MSHTML) that allows writing data outside the memory of operable objects;\n * Three Google Chrome vulnerabilities found in the wild that exploit bugs in various browser components: [CVE-2021-30551](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-30551>) \u2014 a data type confusion vulnerability in the V8 scripting engine; [CVE-2021-30554](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-30554>) \u2014 a use-after-free vulnerability in the WebGL component; and [CVE-2021-21220](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-21220>) \u2014 a heap corruption vulnerability;\n * Three vulnerabilities in the WebKit browser engine, now used mainly in Apple products (for example, the Safari browser), were also found in the wild: [CVE-2021-30661](<https://support.apple.com/en-us/HT212317>) \u2014 a use-after-free vulnerability; [CVE-2021-30665](<https://support.apple.com/en-us/HT212336>) \u2014 a memory corruption vulnerability; and [CVE-2021-30663](<https://support.apple.com/en-us/HT212336>) \u2014 an integer overflow vulnerability.\n\nAll of these vulnerabilities allow a cybercriminal to attack a system unnoticed if the user opens a malicious site in an unpatched browser.\n\nIn Q2, two similar vulnerabilities were found ([CVE-2021-31201](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-31201>) and [CVE-2021-31199](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-31199>)), exploiting integer overflow bugs in the Microsoft Windows Cryptographic Provider component. Using these vulnerabilities, an attacker could prepare a special signed document that would ultimately allow the execution of arbitrary code in the context of an application that uses the vulnerable library.\n\nBut the biggest talking point of the quarter was the [critical vulnerabilities CVE-2021-1675 and CVE-2021-34527](<https://securelist.com/quick-look-at-cve-2021-1675-cve-2021-34527-aka-printnightmare/103123/>) in the Microsoft Windows Print Spooler, in both server and client editions. Their discovery, together with a [proof of concept](<https://encyclopedia.kaspersky.com/glossary/poc-proof-of-concept/?utm_source=securelist&utm_medium=blog&utm_campaign=termin-explanation>), caused a stir in both the expert community and the media, which dubbed one of the vulnerabilities PrintNightmare. Exploitation of these vulnerabilities is quite trivial, since Print Spooler is enabled by default in Windows, and the methods of compromise are available even to unprivileged users, including remote ones. In the latter case, the RPC mechanism can be leveraged for compromise. As a result, an attacker with low-level access can take over not only a local machine, but also the domain controller, if these systems have not been updated, or available [risk mitigation methods](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34527>) against these vulnerabilities have not been applied.\n\nAmong the network threats in Q2 2021, attempts to brute-force passwords in popular protocols and services (RDP, SSH, MSSQL, etc.) are still current. Attacks using EternalBlue, EternalRomance and other such exploits remain prevalent, although their share is gradually shrinking. New attacks include [CVE-2021-31166](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-31166>), a vulnerability in the Microsoft Windows HTTP protocol stack that causes a denial of service during processing of web-server requests. To gain control over target systems, attackers are also using the previously found NetLogon vulnerability ([CVE-2020-1472](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2020-1472>)) and, for servers running Microsoft Exchange Server, vulnerabilities recently discovered while researching targeted attacks by the [HAFNIUM](<https://www.microsoft.com/security/blog/2021/03/02/hafnium-targeting-exchange-servers/>) group.\n\n## Attacks on macOS\n\nAs for threats to the macOS platform, Q2 will be remembered primarily for the appearance of new samples of the XCSSET Trojan. Designed to steal data from browsers and other applications, the malware is notable for spreading itself through infecting projects in the Xcode development environment. The Trojan takes the form of a bash script packed with the SHC utility, allowing it to evade macOS protection, which does not block script execution. During execution of the script, the SHC utility uses the RC4 algorithm to decrypt the payload, which, in turn, downloads additional modules.\n\n**Top 20 threats for macOS**\n\n| **Verdict** | **%*** \n---|---|--- \n1 | AdWare.OSX.Pirrit.j | 14.47 \n2 | AdWare.OSX.Pirrit.ac | 13.89 \n3 | AdWare.OSX.Pirrit.o | 10.21 \n4 | AdWare.OSX.Pirrit.ae | 7.96 \n5 | AdWare.OSX.Bnodlero.at | 7.94 \n6 | Monitor.OSX.HistGrabber.b | 7.82 \n7 | Trojan-Downloader.OSX.Shlayer.a | 7.69 \n8 | AdWare.OSX.Bnodlero.bg | 7.28 \n9 | AdWare.OSX.Pirrit.aa | 6.84 \n10 | AdWare.OSX.Pirrit.gen | 6.44 \n11 | AdWare.OSX.Cimpli.m | 5.53 \n12 | Trojan-Downloader.OSX.Agent.h | 5.50 \n13 | Backdoor.OSX.Agent.z | 4.64 \n14 | Trojan-Downloader.OSX.Lador.a | 3.92 \n15 | AdWare.OSX.Bnodlero.t | 3.64 \n16 | AdWare.OSX.Bnodlero.bc | 3.36 \n17 | AdWare.OSX.Ketin.h | 3.25 \n18 | AdWare.OSX.Bnodlero.ay | 3.08 \n19 | AdWare.OSX.Pirrit.q | 2.84 \n20 | AdWare.OSX.Pirrit.x | 2.56 \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 in the previous quarter, a total of 15 of the Top 20 threats for macOS are adware programs.

Each year we\u2019ve looked back at all of the detected and disclosed in-the-wild 0-days as a group and synthesized what we think the trends and takeaways are. The goal of this report is not to detail each individual exploit, but instead to analyze the exploits from the year as a group, looking for trends, gaps, lessons learned, successes, etc. If you\u2019re interested in the analysis of individual exploits, please check out our [root cause analysis repository](<https://googleprojectzero.blogspot.com/p/rca.html>).\n\nWe perform and share this analysis in order to make 0-day hard. We want it to be more costly, more resource intensive, and overall more difficult for attackers to use 0-day capabilities. 2021 highlighted just how important it is to stay relentless in our pursuit to make it harder for attackers to exploit users with 0-days. We heard [over](<https://forbiddenstories.org/about-the-pegasus-project/>) and [over](<https://citizenlab.ca/2021/07/hooking-candiru-another-mercenary-spyware-vendor-comes-into-focus/>) and [over](<https://www.amnesty.org/en/latest/research/2021/11/devices-of-palestinian-human-rights-defenders-hacked-with-nso-groups-pegasus-spyware-2/>) about how governments were targeting journalists, minoritized populations, politicians, human rights defenders, and even security researchers around the world. The decisions we make in the security and tech communities can have real impacts on society and our fellow humans\u2019 lives.\n\nWe\u2019ll provide our evidence and process for our conclusions in the body of this post, and then wrap it all up with our thoughts on next steps and hopes for 2022 in the conclusion. If digging into the bits and bytes is not your thing, then feel free to just check-out the Executive Summary and Conclusion.\n\n# Executive Summary\n\n2021 included the detection and disclosure of 58 in-the-wild 0-days, the most ever recorded since Project Zero began tracking in mid-2014. That\u2019s more than double the previous maximum of 28 detected in 2015 and especially stark when you consider that there were only 25 detected in 2020. We\u2019ve tracked publicly known in-the-wild 0-day exploits in [this spreadsheet](<https://docs.google.com/spreadsheets/d/1lkNJ0uQwbeC1ZTRrxdtuPLCIl7mlUreoKfSIgajnSyY/edit#gid=0>) since mid-2014.\n\nWhile we often talk about the number of 0-day exploits used in-the-wild, what we\u2019re actually discussing is the number of 0-day exploits detected and disclosed as in-the-wild. And that leads into our first conclusion: we believe the large uptick in in-the-wild 0-days in 2021 is due to increased detection and disclosure of these 0-days, rather than simply increased usage of 0-day exploits.\n\nWith this record number of in-the-wild 0-days to analyze we saw that attacker methodology hasn\u2019t actually had to change much from previous years. Attackers are having success using the same bug patterns and exploitation techniques and going after the same attack surfaces. Project Zero\u2019s mission is \u201cmake 0day hard\u201d. 0-day will be harder when, overall, attackers are not able to use public methods and techniques for developing their 0-day exploits. When we look over these 58 0-days used in 2021, what we see instead are 0-days that are similar to previous & publicly known vulnerabilities. Only two 0-days stood out as novel: one for the technical sophistication of its exploit and the other for its use of logic bugs to escape the sandbox.\n\nSo while we recognize the industry\u2019s improvement in the detection and disclosure of in-the-wild 0-days, we also acknowledge that there\u2019s a lot more improving to be done. Having access to more \u201cground truth\u201d of how attackers are actually using 0-days shows us that they are able to have success by using previously known techniques and methods rather than having to invest in developing novel techniques. This is a clear area of opportunity for the tech industry.\n\nWe had so many more data points in 2021 to learn about attacker behavior than we\u2019ve had in the past. Having all this data, though, has left us with even more questions than we had before. Unfortunately, attackers who actively use 0-day exploits do not share the 0-days they\u2019re using or what percentage of 0-days we\u2019re missing in our tracking, so we\u2019ll never know exactly what proportion of 0-days are currently being found and disclosed publicly. \n\nBased on our analysis of the 2021 0-days we hope to see the following progress in 2022 in order to continue taking steps towards making 0-day hard:\n\n 1. All vendors agree to disclose the in-the-wild exploitation status of vulnerabilities in their security bulletins.\n 2. Exploit samples or detailed technical descriptions of the exploits are shared more widely.\n 3. Continued concerted efforts on reducing memory corruption vulnerabilities or rendering them unexploitable.Launch mitigations that will significantly impact the exploitability of memory corruption vulnerabilities.\n\n# A Record Year for In-the-Wild 0-days\n\n2021 was a record year for in-the-wild 0-days. So what happened?\n\n[](<https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjC72HVhQEdwHNIzMiyb18bUFr6hPCWJiKL2Mm43-tW11qc0ucOPI8A9oChEXQe0-QNOBF83SIcfyjcyvPveuWvgipbiBzHWqZTx2-LilJFYIbx6uQeno9f481HJQ0CgylQkh8Ks7AbGC6tjhYDNBcI7jh6ihhzJATA0r_P4bQUBm-1lmHp2DPvWM6I/s1200/image1%287%29.png>)\n\nIs it that software security is getting worse? Or is it that attackers are using 0-day exploits more? Or has our ability to detect and disclose 0-days increased? When looking at the significant uptick from 2020 to 2021, we think it's mostly explained by the latter. While we believe there has been a steady growth in interest and investment in 0-day exploits by attackers in the past several years, and that security still needs to urgently improve, it appears that the security industry's ability to detect and disclose in-the-wild 0-day exploits is the primary explanation for the increase in observed 0-day exploits in 2021.\n\nWhile we often talk about \u201c0-day exploits used in-the-wild\u201d, what we\u2019re actually tracking are \u201c0-day exploits detected and disclosed as used in-the-wild\u201d. There are more factors than just the use that contribute to an increase in that number, most notably: detection and disclosure. Better detection of 0-day exploits and more transparently disclosed exploited 0-day vulnerabilities is a positive indicator for security and progress in the industry. \n\nOverall, we can break down the uptick in the number of in-the-wild 0-days into:\n\n * More detection of in-the-wild 0-day exploits\n * More public disclosure of in-the-wild 0-day exploitation\n\n## More detection\n\nIn the [2019 Year in Review](<https://googleprojectzero.blogspot.com/2020/07/detection-deficit-year-in-review-of-0.html>), we wrote about the \u201cDetection Deficit\u201d. We stated \u201cAs a community, our ability to detect 0-days being used in the wild is severely lacking to the point that we can\u2019t draw significant conclusions due to the lack of (and biases in) the data we have collected.\u201d In the last two years, we believe that there\u2019s been progress on this gap. \n\nAnecdotally, we hear from more people that they\u2019ve begun working more on detection of 0-day exploits. Quantitatively, while a very rough measure, we\u2019re also seeing the number of entities credited with reporting in-the-wild 0-days increasing. It stands to reason that if the number of people working on trying to find 0-day exploits increases, then the number of in-the-wild 0-day exploits detected may increase.\n\n[](<https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiMbFpoEKSSn5AbAzsovaZ0yN6_OFXo9u4hpDCXJBpro8LRUWJlVQ9CSqtzT2V9ohrhOvP3_RnrYsOzFGPK0FZGJmW2713g2vVW82ReJVXpjAZc57BCxtHg8i-6AdR_ThDZB6UKvzAKekbmAkuUBliMyDyWSBW87z4ZZQJC3KX-_ptZIHveotLGoJ9I/s1200/image5%284%29.png>)\n\n[](<https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgRS0t_2Bwvc3U_EIr5h7NcWpQyjzHCPb4OMiDpzPxPs587otAEj8bzwch8UMFlgKchwdSq4L_PXRn1O6KGLHUl4X9voLBdZJNQsgQyJcMCVB4Y8-aRHaXRpOYZw7KVtyNYwdWpwX8ILUV1fyG2kDsXVWORsSPUBGVTON90gWf9POhhxA4edxNe1eoV/s1200/image2%285%29.png>)\n\nWe\u2019ve also seen the number of vendors detecting in-the-wild 0-days in their own products increasing. Whether or not these vendors were previously working on detection, vendors seem to have found ways to be more successful in 2021. Vendors likely have the most telemetry and overall knowledge and visibility into their products so it\u2019s important that they are investing in (and hopefully having success in) detecting 0-days targeting their own products. As shown in the chart above, there was a significant increase in the number of in-the-wild 0-days discovered by vendors in their own products. Google discovered 7 of the in-the-wild 0-days in their own products and Microsoft discovered 10 in their products!\n\n## More disclosure\n\nThe second reason why the number of detected in-the-wild 0-days has increased is due to more disclosure of these vulnerabilities. Apple and Google Android (we differentiate \u201cGoogle Android\u201d rather than just \u201cGoogle\u201d because Google Chrome has been annotating their security bulletins for the last few years) first began labeling vulnerabilities in their security advisories with the information about potential in-the-wild exploitation in November 2020 and January 2021 respectively. When vendors don\u2019t annotate their release notes, the only way we know that a 0-day was exploited in-the-wild is if the researcher who discovered the exploitation comes forward. If Apple and Google Android had not begun annotating their release notes, the public would likely not know about at least 7 of the Apple in-the-wild 0-days and 5 of the Android in-the-wild 0-days. Why? Because these vulnerabilities were reported by \u201cAnonymous\u201d reporters. If the reporters didn\u2019t want credit for the vulnerability, it\u2019s unlikely that they would have gone public to say that there were indications of exploitation. That is 12 0-days that wouldn\u2019t have been included in this year\u2019s list if Apple and Google Android had not begun transparently annotating their security advisories. \n\n[](<https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjPe_J-0Wu9Ap-0n3Yj5BoXiWTnjViyyGasIChhb3juADZosK9nTbyiaWtzuRyjwG3frQNjLsvRMRoQHrFfo1iKa3GjmcuLHqat40GcoechQ16XbhpVGwF7m_TJ0Oucvy3wvm8x0aXbVnJfhkG2FNkxI4cJf5ONBqEYnPxQDUmZChvByLHE8OzSU20N/s1200/image3%287%29.png>)\n\nKudos and thank you to Microsoft, Google Chrome, and Adobe who have been annotating their security bulletins for transparency for multiple years now! And thanks to Apache who also annotated their release notes for [CVE-2021-41773](<https://httpd.apache.org/security/vulnerabilities_24.html>) this past year. \n\nIn-the-wild 0-days in Qualcomm and ARM products were annotated as in-the-wild in Android security bulletins, but not in the vendor\u2019s own security advisories.\n\nIt's highly likely that in 2021, there were other 0-days that were exploited in the wild and detected, but vendors did not mention this in their release notes. In 2022, we hope that more vendors start noting when they patch vulnerabilities that have been exploited in-the-wild. Until we\u2019re confident that all vendors are transparently disclosing in-the-wild status, there\u2019s a big question of how many in-the-wild 0-days are discovered, but not labeled publicly by vendors.\n\n# New Year, Old Techniques\n\nWe had a record number of \u201cdata points\u201d in 2021 to understand how attackers are actually using 0-day exploits. A bit surprising to us though, out of all those data points, there was nothing new amongst all this data. 0-day exploits are considered one of the most advanced attack methods an actor can use, so it would be easy to conclude that attackers must be using special tricks and attack surfaces. But instead, the 0-days we saw in 2021 generally followed the same bug patterns, attack surfaces, and exploit \u201cshapes\u201d previously seen in public research. Once \u201c0-day is hard\u201d, we\u2019d expect that to be successful, attackers would have to find new bug classes of vulnerabilities in new attack surfaces using never before seen exploitation methods. In general, that wasn't what the data showed us this year. With two exceptions (described below in the iOS section) out of the 58, everything we saw was pretty \u201c[meh](<https://www.dictionary.com/browse/meh#:~:text=unimpressive%3B%20boring%3A>)\u201d or standard.\n\nOut of the 58 in-the-wild 0-days for the year, 39, or 67% were memory corruption vulnerabilities. Memory corruption vulnerabilities have been the standard for attacking software for the last few decades and it\u2019s still how attackers are having success. Out of these memory corruption vulnerabilities, the majority also stuck with very popular and well-known bug classes:\n\n * 17 use-after-free\n * 6 out-of-bounds read & write\n * 4 buffer overflow\n * 4 integer overflow\n\nIn the next sections we\u2019ll dive into each major platform that we saw in-the-wild 0-days for this year. We\u2019ll share the trends and explain why what we saw was pretty unexceptional.\n\n## Chromium (Chrome)\n\nChromium had a record high number of 0-days detected and disclosed in 2021 with 14. Out of these 14, 10 were renderer remote code execution bugs, 2 were sandbox escapes, 1 was an infoleak, and 1 was used to open a webpage in Android apps other than Google Chrome.\n\nThe 14 0-day vulnerabilities were in the following components:\n\n * 6 JavaScript Engine - v8 ([CVE-2021-21148](<https://chromereleases.googleblog.com/2021/02/stable-channel-update-for-desktop_4.html>), [CVE-2021-30551](<https://chromereleases.googleblog.com/2021/02/stable-channel-update-for-desktop_4.html>), [CVE-2021-30563](<https://chromereleases.googleblog.com/2021/07/stable-channel-update-for-desktop.html>), [CVE-2021-30632](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-30632.html>), [CVE-2021-37975](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-37975.html>), [CVE-2021-38003](<https://chromereleases.googleblog.com/2021/10/stable-channel-update-for-desktop_28.html>))\n * 2 DOM Engine - Blink ([CVE-2021-21193](<https://chromereleases.googleblog.com/2021/03/stable-channel-update-for-desktop_12.html>) & [CVE-2021-21206](<https://chromereleases.googleblog.com/2021/04/stable-channel-update-for-desktop.html>))\n * 1 WebGL ([CVE-2021-30554](<https://chromereleases.googleblog.com/2021/06/stable-channel-update-for-desktop_17.html>))\n * 1 IndexedDB ([CVE-2021-30633](<https://chromereleases.googleblog.com/2021/09/stable-channel-update-for-desktop.html>))\n * 1 webaudio ([CVE-2021-21166](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-21166.html>))\n * 1 Portals ([CVE-2021-37973](<https://chromereleases.googleblog.com/2021/09/stable-channel-update-for-desktop_24.html>))\n * 1 Android Intents ([CVE-2021-38000](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-38000.html>))\n * 1 Core ([CVE-2021-37976](<https://chromereleases.googleblog.com/2021/09/stable-channel-update-for-desktop_30.html>))\n\nWhen we look at the components targeted by these bugs, they\u2019re all attack surfaces seen before in public security research and previous exploits. If anything, there are a few less DOM bugs and more targeting these other components of browsers like IndexedDB and WebGL than previously. 13 out of the 14 Chromium 0-days were memory corruption bugs. Similar to last year, most of those memory corruption bugs are use-after-free vulnerabilities.\n\nA couple of the Chromium bugs were even similar to previous in-the-wild 0-days. [CVE-2021-21166](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-21166.html>) is an issue in ScriptProcessorNode::Process() in webaudio where there\u2019s insufficient locks such that buffers are accessible in both the main thread and the audio rendering thread at the same time. [CVE-2019-13720](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2019/CVE-2019-13720.html>) is an in-the-wild 0-day from 2019. It was a vulnerability in ConvolverHandler::Process() in webaudio where there were also insufficient locks such that a buffer was accessible in both the main thread and the audio rendering thread at the same time.\n\n[CVE-2021-30632](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-30632.html>) is another Chromium in-the-wild 0-day from 2021. It\u2019s a type confusion in the TurboFan JIT in Chromium\u2019s JavaScript Engine, v8, where Turbofan fails to deoptimize code after a property map is changed. [CVE-2021-30632](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-30632.html>) in particular deals with code that stores global properties. [CVE-2020-16009](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2020/CVE-2020-16009.html>) was also an in-the-wild 0-day that was due to Turbofan failing to deoptimize code after map deprecation.\n\n## WebKit (Safari)\n\nPrior to 2021, Apple had only acknowledged 1 publicly known in-the-wild 0-day targeting WebKit/Safari, and that was due the sharing by an external researcher. In 2021 there were 7. This makes it hard for us to assess trends or changes since we don\u2019t have historical samples to go off of. Instead, we\u2019ll look at 2021\u2019s WebKit bugs in the context of other Safari bugs not known to be in-the-wild and other browser in-the-wild 0-days. \n\nThe 7 in-the-wild 0-days targeted the following components:\n\n * 4 Javascript Engine - JavaScript Core ([CVE-2021-1870](<https://support.apple.com/en-us/HT212146>), [CVE-2021-1871](<https://support.apple.com/en-us/HT212146>), [CVE-2021-30663](<https://support.apple.com/en-us/HT212336>), [CVE-2021-30665](<https://support.apple.com/en-us/HT212336>))\n * 1 IndexedDB ([CVE-2021-30858](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-30858.html>))\n * 1 Storage ([CVE-2021-30661](<https://support.apple.com/en-us/HT212317>))\n * 1 Plugins ([CVE-2021-1879](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-1879.html>))\n\nThe one semi-surprise is that no DOM bugs were detected and disclosed. In previous years, vulnerabilities in the DOM engine have generally made up 15-20% of the in-the-wild browser 0-days, but none were detected and disclosed for WebKit in 2021. \n\nIt would not be surprising if attackers are beginning to shift to other modules, like third party libraries or things like IndexedDB. The modules may be more promising to attackers going forward because there\u2019s a better chance that the vulnerability may exist in multiple browsers or platforms. For example, the webaudio bug in Chromium, [CVE-2021-21166](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-21166.html>), also existed in WebKit and was fixed as [CVE-2021-1844](<https://support.apple.com/en-us/HT212223>), though there was no evidence it was exploited in-the-wild in WebKit. The IndexedDB in-the-wild 0-day that was used against Safari in 2021, [CVE-2021-30858](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-30858.html>), was very, very similar to a [bug fixed in Chromium in January 2020](<https://bugs.chromium.org/p/chromium/issues/detail?id=1032890>).\n\n## Internet Explorer\n\nSince we began tracking in-the-wild 0-days, Internet Explorer has had a pretty consistent number of 0-days each year. 2021 actually tied 2016 for the most in-the-wild Internet Explorer 0-days we\u2019ve ever tracked even though Internet Explorer\u2019s market share of web browser users continues to decrease.\n\n[](<https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjbMTlnGhVLcVL8K20S3s6hSrpyB6kZAA9CWvWNpn1isbEbLFv0c2rs_dPvM0ALT45NtTvyhp8rGehGDRIAEJ6OZYSkk5mezOEoPJOquVXXyHeqrVOvRGEiQHv_J7Je8Itjc5qhwXMCR-E4y79abuxiddCYoeF2VrVakY-L1q82NeMEPjTA0fFC-t8h/s1200/image4%286%29.png>)\n\nSo why are we seeing so little change in the number of in-the-wild 0-days despite the change in market share? Internet Explorer is still a ripe attack surface for initial entry into Windows machines, even if the user doesn\u2019t use Internet Explorer as their Internet browser. While the number of 0-days stayed pretty consistent to what we\u2019ve seen in previous years, the components targeted and the delivery methods of the exploits changed. 3 of the 4 0-days seen in 2021 targeted the MSHTML browser engine and were delivered via methods other than the web. Instead they were delivered to targets via Office documents or other file formats. \n\nThe four 0-days targeted the following components:\n\n * MSHTML browser engine ([CVE-2021-26411](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-26411.html>), [CVE-2021-33742](<https://googleprojectzero.github.io/0days-in-the-wild/0day-RCAs/2021/CVE-2021-33742.html>), [CVE-2021-40444](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-40444>))\n * Javascript Engine - JScript9 ([CVE-2021-34448](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34448>))\n\nFor [CVE-2021-26411](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-26411.html>) targets of the campaign initially received a .mht file, which prompted the user to open in Internet Explorer. Once it was opened in Internet Explorer, the exploit was downloaded and run. [CVE-2021-33742](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-33742.html>) and [CVE-2021-40444](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-40444>) were delivered to targets via malicious Office documents.\n\n[CVE-2021-26411](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-26411.html>) and [CVE-2021-33742](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-33742.html>) were two common memory corruption bug patterns: a use-after-free due to a user controlled callback in between two actions using an object and the user frees the object during that callback and a buffer overflow.\n\nThere were a few different vulnerabilities used in the exploit chain that used [CVE-2021-40444](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-40444>), but the one within MSHTML was that as soon as the Office document was opened the payload would run: a CAB file was downloaded, decompressed, and then a function from within a DLL in that CAB was executed. Unlike the previous two MSHTML bugs, this was a logic error in URL parsing rather than a memory corruption bug.\n\n## Windows\n\nWindows is the platform where we\u2019ve seen the most change in components targeted compared with previous years. However, this shift has generally been in progress for a few years and predicted with the end-of-life of Windows 7 in 2020 and thus why it\u2019s still not especially novel.\n\nIn 2021 there were 10 Windows in-the-wild 0-days targeting 7 different components:\n\n * 2 Enhanced crypto provider ([CVE-2021-31199](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-31199>), [CVE-2021-31201](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-31201>))\n * 2 NTOS kernel ([CVE-2021-33771](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-33771>), [CVE-2021-31979](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-31979>))\n * 2 Win32k ([CVE-2021-1732](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-1732.html>), [CVE-2021-40449](<https://securelist.com/mysterysnail-attacks-with-windows-zero-day/104509/>))\n * 1 Windows update medic ([CVE-2021-36948](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-36948>)) \n * 1 SuperFetch ([CVE-2021-31955](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-31955>))\n * 1 dwmcore.dll ([CVE-2021-28310](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-28310>))\n * 1 ntfs.sys ([CVE-2021-31956](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-31956>))\n\nThe number of different components targeted is the shift from past years. For example, in 2019 75% of Windows 0-days targeted Win32k while in 2021 Win32k only made up 20% of the Windows 0-days. The reason that this was expected and predicted was that 6 out of 8 of those 0-days that targeted Win32k in 2019 did not target the latest release of Windows 10 at that time; they were targeting older versions. With Windows 10 Microsoft began dedicating more and more resources to locking down the attack surface of Win32k so as those older versions have hit end-of-life, Win32k is a less and less attractive attack surface.\n\nSimilar to the many Win32k vulnerabilities seen over the years, the two 2021 Win32k in-the-wild 0-days are due to custom user callbacks. The user calls functions that change the state of an object during the callback and Win32k does not correctly handle those changes. [CVE-2021-1732](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-1732.html>) is a type confusion vulnerability due to a user callback in xxxClientAllocWindowClassExtraBytes which leads to out-of-bounds read and write. If NtUserConsoleControl is called during the callback a flag is set in the window structure to signal that a field is an offset into the kernel heap. xxxClientAllocWindowClassExtraBytes doesn\u2019t check this and writes that field as a user-mode pointer without clearing the flag. The first in-the-wild 0-day detected and disclosed in 2022, [CVE-2022-21882](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2022/CVE-2022-21882.html>), is due to [CVE-2021-1732](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-1732.html>) actually not being fixed completely. The attackers found a way to bypass the original patch and still trigger the vulnerability. [CVE-2021-40449](<https://securelist.com/mysterysnail-attacks-with-windows-zero-day/104509/>) is a use-after-free in NtGdiResetDC due to the object being freed during the user callback. \n\n## iOS/macOS\n\nAs discussed in the \u201cMore disclosure\u201d section above, 2021 was the first full year that Apple annotated their release notes with in-the-wild status of vulnerabilities. 5 iOS in-the-wild 0-days were detected and disclosed this year. The first publicly known macOS in-the-wild 0-day ([CVE-2021-30869](<https://blog.google/threat-analysis-group/analyzing-watering-hole-campaign-using-macos-exploits/>)) was also found. In this section we\u2019re going to discuss iOS and macOS together because: 1) the two operating systems include similar components and 2) the sample size for macOS is very small (just this one vulnerability).\n\n[](<https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhPGaOlQUGIYyvpDY_M0rGh3JekH4mwXHfN459HYcklg74v4Mfp8j6fgh2SM09mjhA4svdgN_TdSN3R5Bb-DJTHnlo63qnRTsvLs1EZgAE3fBpRtsZhxKhyBNTb_khdS6mNT3EtSHnS_R-TshtHx-gSWnEPpHjmSqO_9Y7JxupGcDKZ0-xwsxgbX6zR/s1200/image6%284%29.png>)\n\nFor the 5 total iOS and macOS in-the-wild 0-days, they targeted 3 different attack surfaces:\n\n * IOMobileFrameBuffer ([CVE-2021-30807](<https://support.apple.com/en-us/HT212623>), [CVE-2021-30883](<https://support.apple.com/en-us/HT212846>))\n * XNU Kernel ([CVE-2021-1782](<https://support.apple.com/en-us/HT212146>) & [CVE-2021-30869](<https://blog.google/threat-analysis-group/analyzing-watering-hole-campaign-using-macos-exploits/>))\n * CoreGraphics ([CVE-2021-30860](<https://googleprojectzero.blogspot.com/2021/12/a-deep-dive-into-nso-zero-click.html>))\n * CommCenter ([FORCEDENTRY sandbox escape](<https://googleprojectzero.blogspot.com/2022/03/forcedentry-sandbox-escape.html>) \\- CVE requested, not yet assigned)\n\nThese 4 attack surfaces are not novel. IOMobileFrameBuffer has been a target of public security research for many years. For example, the Pangu Jailbreak from 2016 used [CVE-2016-4654](<https://www.blackhat.com/docs/us-16/materials/us-16-Wang-Pangu-9-Internals.pdf>), a heap buffer overflow in IOMobileFrameBuffer. IOMobileFrameBuffer manages the screen\u2019s frame buffer. For iPhone 11 (A13) and below, IOMobileFrameBuffer was a kernel driver. Beginning with A14, it runs on a coprocessor, the DCP. It\u2019s a popular attack surface because historically it\u2019s been accessible from sandboxed apps. In 2021 there were two in-the-wild 0-days in IOMobileFrameBuffer. [CVE-2021-30807](<https://support.apple.com/en-us/HT212623>) is an out-of-bounds read and [CVE-2021-30883](<https://support.apple.com/en-us/HT212846>) is an integer overflow, both common memory corruption vulnerabilities. In 2022, we already have another in-the-wild 0-day in IOMobileFrameBuffer, [CVE-2022-22587](<https://support.apple.com/en-us/HT213053>).\n\nOne iOS 0-day and the macOS 0-day both exploited vulnerabilities in the XNU kernel and both vulnerabilities were in code related to XNU\u2019s inter-process communication (IPC) functionality. [CVE-2021-1782](<https://support.apple.com/en-us/HT212146>) exploited a vulnerability in mach vouchers while [CVE-2021-30869](<https://blog.google/threat-analysis-group/analyzing-watering-hole-campaign-using-macos-exploits/>) exploited a vulnerability in mach messages. This is not the first time we\u2019ve seen iOS in-the-wild 0-days, much less public security research, targeting mach vouchers and mach messages. [CVE-2019-6625](<https://support.apple.com/en-us/HT209443>) was exploited as a part of [an exploit chain targeting iOS 11.4.1-12.1.2](<https://googleprojectzero.blogspot.com/2019/08/in-wild-ios-exploit-chain-5.html>) and was also a [vulnerability in mach vouchers](<https://googleprojectzero.blogspot.com/2019/01/voucherswap-exploiting-mig-reference.html>). \n\nMach messages have also been a popular target for public security research. In 2020 there were two in-the-wild 0-days also in mach messages: [CVE-2020-27932](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2020/CVE-2020-27932.html>) & [CVE-2020-27950](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2020/CVE-2020-27950.html>). This year\u2019s [CVE-2021-30869](<https://blog.google/threat-analysis-group/analyzing-watering-hole-campaign-using-macos-exploits/>) is a pretty close variant to 2020\u2019s [CVE-2020-27932](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2020/CVE-2020-27932.html>). Tielei Wang and Xinru Chi actually [presented on this vulnerability at zer0con 2021](<https://github.com/wangtielei/Slides/blob/main/zer0con21.pdf>) in April 2021. In their presentation, they explained that they found it while doing variant analysis on [CVE-2020-27932](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2020/CVE-2020-27932.html>). [TieLei Wang explained via Twitter](<https://twitter.com/WangTielei/status/1486266258152726530>) that they had found the vulnerability in December 2020 and had noticed it was fixed in beta versions of iOS 14.4 and macOS 11.2 which is why they presented it at Zer0Con. The in-the-wild exploit only targeted macOS 10, but used the same exploitation technique as the one presented.\n\nThe two FORCEDENTRY exploits ([CVE-2021-30860](<https://googleprojectzero.blogspot.com/2021/12/a-deep-dive-into-nso-zero-click.html>) and the [sandbox escape](<https://googleprojectzero.blogspot.com/2022/03/forcedentry-sandbox-escape.html>)) were the only times that made us all go \u201cwow!\u201d this year. For [CVE-2021-30860](<https://googleprojectzero.blogspot.com/2021/12/a-deep-dive-into-nso-zero-click.html>), the integer overflow in CoreGraphics, it was because: \n\n 1. For years we\u2019ve all heard about how attackers are using 0-click iMessage bugs and finally we have a public example, and\n 2. The exploit was an impressive work of art. \n\nThe sandbox escape (CVE requested, not yet assigned) was impressive because it\u2019s one of the few times we\u2019ve seen a sandbox escape in-the-wild that uses only logic bugs, rather than the standard memory corruption bugs. \n\nFor [CVE-2021-30860](<https://googleprojectzero.blogspot.com/2021/12/a-deep-dive-into-nso-zero-click.html>), the vulnerability itself wasn\u2019t especially notable: a classic integer overflow within the JBIG2 parser of the CoreGraphics PDF decoder. The exploit, though, was described by Samuel Gro\u00df & Ian Beer as \u201cone of the most technically sophisticated exploits [they]\u2019ve ever seen\u201d. [Their blogpost shares all the details](<https://googleprojectzero.blogspot.com/2021/12/a-deep-dive-into-nso-zero-click.html>), but the highlight is that the exploit uses the logical operators available in JBIG2 to build NAND gates which are used to build its own computer architecture. The exploit then writes the rest of its exploit using that new custom architecture. From their blogpost:\n\nUsing over 70,000 segment commands defining logical bit operations, they define a small computer architecture with features such as registers and a full 64-bit adder and comparator which they use to search memory and perform arithmetic operations. It's not as fast as Javascript, but it's fundamentally computationally equivalent.\n\nThe bootstrapping operations for the sandbox escape exploit are written to run on this logic circuit and the whole thing runs in this weird, emulated environment created out of a single decompression pass through a JBIG2 stream. It's pretty incredible, and at the same time, pretty terrifying.\n\nThis is an example of what making 0-day exploitation hard could look like: attackers having to develop a new and novel way to exploit a bug and that method requires lots of expertise and/or time to develop. This year, the two FORCEDENTRY exploits were the only 0-days out of the 58 that really impressed us. Hopefully in the future, the bar has been raised such that this will be required for any successful exploitation.\n\n## Android\n\nThere were 7 Android in-the-wild 0-days detected and disclosed this year. Prior to 2021 there had only been 1 and it was in 2019: [CVE-2019-2215](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2019/CVE-2019-2215.html>). Like WebKit, this lack of data makes it hard for us to assess trends and changes. Instead, we\u2019ll compare it to public security research.\n\nFor the 7 Android 0-days they targeted the following components:\n\n * Qualcomm Adreno GPU driver ([CVE-2020-11261](<https://source.android.com/security/bulletin/2021-01-01>), [CVE-2021-1905](<https://googleprojectzero.github.io/0days-in-the-wild/0day-RCAs/2021/CVE-2021-1905.html>), [CVE-2021-1906](<https://source.android.com/security/bulletin/2021-05-01>))\n * ARM Mali GPU driver ([CVE-2021-28663](<https://source.android.com/security/bulletin/2021-05-01>), [CVE-2021-28664](<https://source.android.com/security/bulletin/2021-05-01>))\n * Upstream Linux kernel ([CVE-2021-1048](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-1048.html>), [CVE-2021-0920](<https://source.android.com/security/bulletin/2021-11-01#kernel-components>))\n\n5 of the 7 0-days from 2021 targeted GPU drivers. This is actually not that surprising when we consider the evolution of the Android ecosystem as well as recent public security research into Android. The Android ecosystem is quite fragmented: many different kernel versions, different manufacturer customizations, etc. If an attacker wants a capability against \u201cAndroid devices\u201d, they generally need to maintain many different exploits to have a decent percentage of the Android ecosystem covered. However, if the attacker chooses to target the GPU kernel driver instead of another component, they will only need to have two exploits since most Android devices use 1 of 2 GPUs: either the Qualcomm Adreno GPU or the ARM Mali GPU. \n\nPublic security research mirrored this choice in the last couple of years as well. When developing full exploit chains (for defensive purposes) to target Android devices, [Guang Gong](<https://github.com/secmob/TiYunZong-An-Exploit-Chain-to-Remotely-Root-Modern-Android-Devices/blob/master/us-20-Gong-TiYunZong-An-Exploit-Chain-to-Remotely-Root-Modern-Android-Devices-wp.pdf>), [Man Yue Mo](<https://securitylab.github.com/research/one_day_short_of_a_fullchain_android/>), and [Ben Hawkes](<https://googleprojectzero.blogspot.com/2020/09/attacking-qualcomm-adreno-gpu.html>) all chose to attack the GPU kernel driver for local privilege escalation. Seeing the in-the-wild 0-days also target the GPU was more of a confirmation rather than a revelation. Of the 5 0-days targeting GPU drivers, 3 were in the Qualcomm Adreno driver and 2 in the ARM Mali driver. \n\nThe two non-GPU driver 0-days ([CVE-2021-0920](<https://source.android.com/security/bulletin/2021-11-01#kernel-components>) and [CVE-2021-1048](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-1048.html>)) targeted the upstream Linux kernel. Unfortunately, these 2 bugs shared a singular characteristic with the Android in-the-wild 0-day seen in 2019: all 3 were previously known upstream before their exploitation in Android. While the sample size is small, it\u2019s still quite striking to see that 100% of the known in-the-wild Android 0-days that target the kernel are bugs that actually were known about before their exploitation.\n\nThe vulnerability now referred to as [CVE-2021-0920](<https://source.android.com/security/bulletin/2021-11-01#kernel-components>) was actually found in September 2016 and [discussed on the Linux kernel mailing lists](<https://lore.kernel.org/lkml/CAOssrKcfncAYsQWkfLGFgoOxAQJVT2hYVWdBA6Cw7hhO8RJ_wQ@mail.gmail.com/>). A [patch was even developed back in 2016](<https://lore.kernel.org/lkml/1475150954-10152-1-git-send-email-mszeredi@redhat.com/>), but it didn\u2019t end up being submitted. The bug was finally [fixed in the Linux kernel in July 2021](<https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=cbcf01128d0a92e131bd09f1688fe032480b65ca>) after the detection of the in-the-wild exploit targeting Android. The patch then made it into the [Android security bulletin in November 2021](<https://source.android.com/security/bulletin/2021-11-01#kernel-components>).\n\n[CVE-2021-1048](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-1048.html>) remained unpatched in Android for 14 months after it was patched in the Linux kernel. The Linux kernel was actually only vulnerable to the issue for a few weeks, but due to Android patching practices, that few weeks became almost a year for some Android devices. If an Android OEM synced to the upstream kernel, then they likely were patched against the vulnerability at some point. But many devices, such as recent Samsung devices, had not and thus were left vulnerable.\n\n## Microsoft Exchange Server\n\nIn 2021, there were 5 in-the-wild 0-days targeting Microsoft Exchange Server. This is the first time any Exchange Server in-the-wild 0-days have been detected and disclosed since we began tracking in-the-wild 0-days. The first four ([CVE-2021-26855](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-26855.html>), [CVE-2021-26857](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-26857>), [CVE-2021-26858](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-26858>), and [CVE-2021-27065](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-27065>)) were all disclosed and patched at the same time and used together in a [single operation](<https://www.microsoft.com/security/blog/2021/03/02/hafnium-targeting-exchange-servers/>). The fifth ([CVE-2021-42321](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-42321>)) was patched on its own in November 2021. [CVE-2021-42321](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-42321>) was demonstrated at Tianfu Cup and then discovered in-the-wild by Microsoft. While no other in-the-wild 0-days were disclosed as part of the chain with [CVE-2021-42321](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-42321>), the attackers would have required at least another 0-day for successful exploitation since [CVE-2021-42321](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-42321>) is a post-authentication bug.\n\nOf the four Exchange in-the-wild 0-days used in the first campaign, [CVE-2021-26855](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-26855.html>), which is also known as \u201cProxyLogon\u201d, is the only one that\u2019s pre-auth. [CVE-2021-26855](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-26855.html>) is a server side request forgery (SSRF) vulnerability that allows unauthenticated attackers to send arbitrary HTTP requests as the Exchange server. The other three vulnerabilities were post-authentication. For example, [CVE-2021-26858](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-26858>) and [CVE-2021-27065](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-27065>) allowed attackers to write arbitrary files to the system. [CVE-2021-26857](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-26857>) is a remote code execution vulnerability due to a deserialization bug in the Unified Messaging service. This allowed attackers to run code as the privileged SYSTEM user.\n\nFor the second campaign, [CVE-2021-42321](<https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-42321>), like [CVE-2021-26858](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-26858>), is a post-authentication RCE vulnerability due to insecure deserialization. It seems that while attempting to harden Exchange, Microsoft inadvertently introduced another deserialization vulnerability.\n\nWhile there were a significant amount of 0-days in Exchange detected and disclosed in 2021, it\u2019s important to remember that they were all used as 0-day in only two different campaigns. This is an example of why we don\u2019t suggest using the number of 0-days in a product as a metric to assess the security of a product. Requiring the use of four 0-days for attackers to have success is preferable to an attacker only needing one 0-day to successfully gain access.\n\nWhile this is the first time Exchange in-the-wild 0-days have been detected and disclosed since Project Zero began our tracking, this is not unexpected. In 2020 there was [n-day exploitation of Exchange Servers](<https://www.cisa.gov/uscert/ncas/current-activity/2020/03/10/unpatched-microsoft-exchange-servers-vulnerable-cve-2020-0688>). Whether this was the first year that attackers began the 0-day exploitation or if this was the first year that defenders began detecting the 0-day exploitation, this is not an unexpected evolution and we\u2019ll likely see it continue into 2022.\n\n# Outstanding Questions\n\nWhile there has been progress on detection and disclosure, that progress has shown just how much work there still is to do. The more data we gained, the more questions that arose about biases in detection, what we\u2019re missing and why, and the need for more transparency from both vendors and researchers.\n\nUntil the day that attackers decide to happily share all their exploits with us, we can\u2019t fully know what percentage of 0-days are publicly known about. However when we pull together our expertise as security researchers and anecdotes from others in the industry, it paints a picture of some of the data we\u2019re very likely missing. From that, these are some of the key questions we\u2019re asking ourselves as we move into 2022:\n\n## Where are the [x] 0-days?\n\nDespite the number of 0-days found in 2021, there are key targets missing from the 0-days discovered. For example, we know that messaging applications like WhatsApp, Signal, Telegram, etc. are targets of interest to attackers and yet there\u2019s only 1 messaging app, in this case iMessage, 0-day found this past year. Since we began tracking in mid-2014 the total is two: a WhatsApp 0-day in 2019 and this iMessage 0-day found in 2021.\n\nAlong with messaging apps, there are other platforms/targets we\u2019d expect to see 0-days targeting, yet there are no or very few public examples. For example, since mid-2014 there\u2019s only one in-the-wild 0-day each for macOS and Linux. There are no known in-the-wild 0-days targeting cloud, CPU vulnerabilities, or other phone components such as the WiFi chip or the baseband.\n\nThis leads to the question of whether these 0-days are absent due to lack of detection, lack of disclosure, or both?\n\n## Do some vendors have no known in-the-wild 0-days because they\u2019ve never been found or because they don\u2019t publicly disclose?\n\nUnless a vendor has told us that they will publicly disclose exploitation status for all vulnerabilities in their platforms, we, the public, don\u2019t know if the absence of an annotation means that there is no known exploitation of a vulnerability or if there is, but the vendor is just not sharing that information publicly. Thankfully this question is something that has a pretty clear solution: all device and software vendors agreeing to publicly disclose when there is evidence to suggest that a vulnerability in their product is being exploited in-the-wild.\n\n## Are we seeing the same bug patterns because that\u2019s what we know how to detect?\n\nAs we described earlier in this report, all the 0-days we saw in 2021 had similarities to previously seen vulnerabilities. This leads us to wonder whether or not that\u2019s actually representative of what attackers are using. Are attackers actually having success exclusively using vulnerabilities in bug classes and components that are previously public? Or are we detecting all these 0-days with known bug patterns because that\u2019s what we know how to detect? Public security research would suggest that yes, attackers are still able to have success with using vulnerabilities in known components and bug classes the majority of the time. But we\u2019d still expect to see a few novel and unexpected vulnerabilities in the grouping. We posed this question back in the 2019 year-in-review and it still lingers. \n\n## Where are the spl0itz?\n\nTo successfully exploit a vulnerability there are two key pieces that make up that exploit: the vulnerability being exploited, and the exploitation method (how that vulnerability is turned into something useful). \n\nUnfortunately, this report could only really analyze one of these components: the vulnerability. Out of the 58 0-days, only 5 have an exploit sample publicly available. Discovered in-the-wild 0-days are the failure case for attackers and a key opportunity for defenders to learn what attackers are doing and make it harder, more time-intensive, more costly, to do it again. Yet without the exploit sample or a detailed technical write-up based upon the sample, we can only focus on fixing the vulnerability rather than also mitigating the exploitation method. This means that attackers are able to continue to use their existing exploit methods rather than having to go back to the design and development phase to build a new exploitation method. While acknowledging that sharing exploit samples can be challenging (we have that challenge too!), we hope in 2022 there will be more sharing of exploit samples or detailed technical write-ups so that we can come together to use every possible piece of information to make it harder for the attackers to exploit more users.\n\nAs an aside, if you have an exploit sample that you\u2019re willing to share with us, please reach out. Whether it\u2019s sharing with us and having us write a detailed technical description and analysis or having us share it publicly, we\u2019d be happy to work with you.\n\n# Conclusion\n\nLooking back on 2021, what comes to mind is \u201cbaby steps\u201d. We can see clear industry improvement in the detection and disclosure of 0-day exploits. But the better detection and disclosure has highlighted other opportunities for progress. As an industry we\u2019re not making 0-day hard. Attackers are having success using vulnerabilities similar to what we\u2019ve seen previously and in components that have previously been discussed as attack surfaces.The goal is to force attackers to start from scratch each time we detect one of their exploits: they\u2019re forced to discover a whole new vulnerability, they have to invest the time in learning and analyzing a new attack surface, they must develop a brand new exploitation method. And while we made distinct progress in detection and disclosure it has shown us areas where that can continue to improve.\n\nWhile this all may seem daunting, the promising part is that we\u2019ve done it before: we have made clear progress on previously daunting goals. In 2019, we discussed the large detection deficit for 0-day exploits and 2 years later more than double were detected and disclosed. So while there is still plenty more work to do, it\u2019s a tractable problem. There are concrete steps that the tech and security industries can take to make it even more progress: \n\n\n 1. Make it an industry standard behavior for all vendors to publicly disclose when there is evidence to suggest that a vulnerability in their product is being exploited,\n 2. Vendors and security researchers sharing exploit samples or detailed descriptions of the exploit techniques.\n 3. Continued concerted efforts on reducing memory corruption vulnerabilities or rendering them unexploitable.\n\nThrough 2021 we continually saw the real world impacts of the use of 0-day exploits against users and entities. Amnesty International, the Citizen Lab, and others highlighted [over](<https://citizenlab.ca/2021/10/breaking-news-new-york-times-journalist-ben-hubbard-pegasus/>) and [over](<https://www.amnesty.org/en/documents/doc10/4491/2021/en/>) how governments were using commercial surveillance products against [journalists](<https://forbiddenstories.org/pegasus-the-new-global-weapon-for-silencing-journalists/>), [human rights defenders](<https://www.amnesty.org/en/latest/research/2021/11/devices-of-palestinian-human-rights-defenders-hacked-with-nso-groups-pegasus-spyware-2/>), and [government officials](<https://www.reuters.com/technology/exclusive-us-state-department-phones-hacked-with-israeli-company-spyware-sources-2021-12-03/>). We saw many enterprises scrambling to remediate and protect themselves from the [Exchange Server 0-days](<https://www.microsoft.com/security/blog/2021/03/02/hafnium-targeting-exchange-servers/>).
