Threat Database Ransomware Kruu Ransomware

Kruu Ransomware

The Kruu Ransomware is another potent variant created from the STOP/Djvu malware family that cybercriminals are using to lock the data of their victims. Files encrypted by Kruu will be completely unusable, and restoration of the data without the needed decryption keys will most likely be impossible. Furthermore, the threat is capable of affecting a large set of different file types, ensuring that the damage it causes will reach most of the data stored on the breached devices.

All encrypted files will be marked by having '.Kruu' appended to their original names. Victims also will notice the presence of a new text file on the compromised systems. Named '_readme.txt,' this file will carry a ransom note with instructions from the hackers.
