There are two malware families that we need to worry about. AcidPour and AcidRain. I don’t know much about neither, but from I read from the article titled Russia unleashes dangerous new wiper both can wipe the drives completely clean.
Both may be able to target raids, so if you run those, be on the lookout.
The one is spelled pour, like I will pour you some soda. The second, AcidRain, is as its spelled, although its one word.
