Recently, the cryptoblackmail scam, “ScamYourself”, has returned to the market – many users
worldwide have been complaining about receiving emails from sender “SaveYourself@856.com”, who claims he hacked their computer and caught them in some awkward situations and will share them publicly unless they pay him in Bitcoin.
In fact, the users receiving these emails have not been infected and there is no RAT controlling their computer (at least not this one…). The malware author has been infecting stations and using them as proxies to send blackmail emails to the victims, and for Monero mining. The victims’ email addresses and passwords were just found in a password dump file and the attacker has been trying his luck with them. The capabilities of the malware are as follows:

Infected files were able to reach more than 110K users in a very short time because of the malware’s spreading capability.
