Many of the services it targets include Microsoft SQL Server, MySQL, Veeam, Exchange, Zoolz, Acronis, Oracle, Backup Exec, Internet Information Server (IIS). Also, it strikes some security programs as well, such as Kaspersky, Malwarebytes, Sophos, and McAfee.
After infecting a target system, it begins encrypting data files whilst renaming them with a .key or .pwnd extension. Though, this encryption is a selective process where the malware skips any specific system and executable files and files in certain folders.

Once complete, the ransomware places the ransom note file entitled “H0w_T0_Rec0very_Files.txt” through the system and desktop. This note includes instructions for obtaining the decryption key.
