Researchers share the findings after analyzing a Windows 32-bit version and an ESXi 64-bit version of BlackSuit, and it appends the file extension .blacksuit to encrypted files and leaves a ransom note that includes information about the attack, a unique ID for the victim, and a TOR chat site link for communication. The malware operators use a data leak site to post leaked data in case a victim does not pay the ransom. Although, as of now, this leak site shows just a single victim.
