New Ransomware "Black Suit" Targets Windows and Linux Platforms

Description

FortiGuard Labs is aware of a report that a new ransomware "Black Suit" targeting both Windows and Linux platforms was discovered in the wild. Some reports suggest similarities with the infamous active Royal ransomware. Black Suit ransomware encrypts files on affected machines and adds a ".BlackSuit" file extension to the encrypted files. It also operates its own leak site on TOR designed to post information stolen from victims.


Why is this Significant?

This is significant because "Black Suit" is a new ransomware that targets both Windows and Linux platforms. The threat actor operates a data leak site on TOR, which typically means that the ransomware targets enterprises.
