A new form of ransomware that has been spotted in the wild uses what researchers call “overkill” levels of encryption to hijack infected systems.

This week, FortiGuard Labs said the new variant, known as Nemty, was recently shared as a sample by a Twitter bot that posts PasteBin links to malware code.

One of the samples shared by the bot was meant to link to a Sodinokibi ransomware variant, but the source ended up being a new malware family altogether.

Sodinokibi, also known as Sodin or REvil, is malware in a constant state of evolution and employs tactics ranging from Windows zero-day exploits to compromised remote management software consoles to infect systems.
