    I know how we can fix ransomware. Let's put a pretty wrapper on a windows feature that is the first thing ransomware deletes and disables

      @GossiTheDog They way they phrase it makes it seem like they're running their own shadow copy. I would be absolutely enraged if I discovered they were just piggybacking on shadow copies.

      @da_667 @GossiTheDog S1 agent blocks deletion of these Volume Shadows. Not sure how it's implemented, but my suspicion is that they either use the VSS AMSI provider to reject the deletion request or they just hook some shit.

      @GossiTheDog don't all malwares delete all shadow copies or do they actually manage to prevent the malware deleting all the snapshots first?

      @GossiTheDog @da_667 most EDR products have the ability to block anything (including root/admin) from killing their processes. I'm sure there's always workarounds (that don't involve single user mode) but it'll stop things like simple kill commands. Crowdstrike has had this feature for years. And it's needed: we used to see hackers breaking in and the first thing they did was kill/remove Crowdstrike. No more...
