[QUOTE="MacDefender, post: 858101, member: 83059"] Using the ESET HIPS rules against ransomware: No effect. Unfortunately this executable isn't a script to start with or started by Explorer necessarily, doesn't use rundll32, doesn't use Office, etc etc. Those are good strong rules though because a lot of ITW ransomware do use those attack vectors. Using the "Protected Folders" technique [URL="https://malwaretips.com/threads/eset-implement-protected-folders-via-hips.96752/"]Discuss - ESET - Implement Protected Folders via HIPS[/URL] was equivalent to CFA: [ATTACH type="full"]233299[/ATTACH] But note that the HIPS says "7-Zip Console" is trying to perform this action, not my TrojanZipperPOC.exe that started 7z.exe. And you can see from that ESET output that ESET says this is a signed application from 6 months ago with good reputation. If you click Deny, 7-zip won't be able to access your documents even when you ask it to from the command line. If you click Allow, then anyone can use 7zip to ransom your files. [/QUOTE]
