The embedded object downloaded a remote template that exploits [CVE-2017-11882](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-11882>) to download and execute the FormBook malware. This vulnerability exists in Microsoft Office 2007 Service Pack 3, Microsoft Office 2010 Service Pack 2, Microsoft Office 2013 Service Pack 1, and Microsoft Office 2016 and allows an attacker to run arbitrary code in the context of the current user by failing to properly handle objects in memory. If the current user is logged on with administrative user rights, this means an attacker could take control of the affected system. The attached Excel document has the same functionality as the embedded excel object in the pdf file. ## IoCs for this campaign ### **Attachments** c421a4309d8fe9fa9bdfe1bde69ccce3 f260e184fb067d3b646af3574e901c05 da4fcf9512dbdf5fa8a6dc88a646100e 7f5da76f29cf8238ed1f944b1d0e587a bb65278dd77988f8a7bad219b524384c ### **C2s** czuj.info vzddc.com habitatsaludable.website modhotels.store maxxflush.com ## Malwarebytes Malwarebytes users were protected against this campaign, because the Malwarebytes Anti-Exploit module blocked the execution of the malware. ![MBAE block](https://blog.malwarebytes.com/wp-content/uploads/2022/03/blocked-600x440.png)_Exploit blocked_ Stay safe, everyone!
