Ransomware has been around for a few years, but it has become an albatross around everyone’s neck, targeting businesses, hospitals, financial institutions and individuals worldwide and extorting millions of dollars.

Dubbed Karmen, the ransomware as a service (RaaS) variant is based on the abandoned open-source ransomware building toolkit dubbed Hidden Tear and is being sold on Dark Web forums from Russian-speaking hacker named DevBitox for $175.

Like any typical ransomware infections, Karmen encrypts files on the infected PC using the strong AES-256 encryption protocol, making them inaccessible to the victim until he/she pays a large sum of money to obtain the decryption key from the attacker.
