[QUOTE="Nightwalker, post: 858358, member: 23015"] Those kind of rules are not good enough for protection, what if the "sponsor" (7-Zip for example) isnt launched in from the default files? The criminals could download the "sponsor" and execute from another place, they could embedded along with the malware, they could execute a different version of the sponsor ... I already saw some ransomwares that use WinRar/7-Zip and do exactly that, so those kind of rules are not that very useful. Edit: ROI Locker is the kind of the ransomware that uses this method that I mentioned before: [SPOILER="ROI Winrar"][/SPOILER] [URL unfurl="true"]https://www.proofpoint.com/us/threat-insight/post/ransomware-explosion-continues-cryptflle2-brlock-mm-locker-discovered[/URL] [/QUOTE]
