Ransom.BlackByte

Ransom.BlackByte is Malwarebytes’ detection name for a a Ransomware-as-a-Service (RaaS) group that encrypts files on compromised systems.

Ransom.BlackByte is ransomware as a service. Ransomware in general makes files on the victims system unusable until the ransom is paid. Ransomware as a service can be delivered in many ways, which depend on the affiliate that is deploying the ransomware. For now, Ransom.BlackByte seems to use a known Microsoft Exchange Server vulnerability to establish a first base and use worm like capabilities to spread across a network.

The BlackByte executable leaves a ransom note in all directories where encryption occurs. The ransom note includes the .onion site that contains instructions for paying the ransom and receiving a decryption key.
