What is Kolz?

Kolz belongs to the Djvu ransomware family. It renames encrypted files by appending a unique extension and creating the "_readme.txt" text file/ransom message in all folders that contain encrypted files. Kolz renames files by appending the ".kolz" extension. For example, "1.jpg" is renamed to "1.jpg.kolz", "2.jpg" to "2.jpg.kolz", and so on.

What is the Bl9c98vcvv ransomware?

Bl9c98vcvv is a malicious program belonging to the Xorist ransomware family. This malware encrypts files stored on infected systems in order to demand payment for decryption. During the encryption process, all affected files are appended with the ".Bl9c98vcvv" extension.

For example, a file originally named something like "1.jpg" would appear as "1.jpg.Bl9c98vcvv" following encryption. Once this process is complete, ransom messages are created in a pop-up window and "HOW TO DECRYPT FILES.txt" text files, which are dropped into compromised folders.

The ransom-demand messages are identical and appear in both English and Portuguese.
