What is BlackBit Ransomware?

BlackBit is the name of a newly discovered strain of ransomware. The new variant belongs to the Loki Locker ransomware family.

The ransomware encrypts most files found on the targeted system. Encrypted file types include document, archive, media and database files.

Encrypted files have their names changed almost completely. A file named "document.doc" will transform into "[spystar@onionmail.org][victim ID]document.doc.BlackBit". The name includes the contact email used by the ransomware operator, the victim's ID code and the ".BlackBit" string.

The ransom note consists of two parts, deposited inside a plain text file named "Restore-My-Files.txt" and a pop-up window. The full ransom note goes as follows:
