Onelock Ransomware is a New MedusaLocker Variant

ransomware

A fresh variant of the MedusaLocker ransomware was spotted in the wild in late November 2022. The new strain goes by the name of Onelock ransomware.

Onelock encrypts the targeted system, leaving files useless and scrambling their contents. Affected file types include media files, documents, archives and executables.

Once files get encrypted, they receive the ".onelock" extension appended after their old one. This will turn a file called "music.mp3" into "music.mp3.onelock" upon encryption.

The ransomware deposits its ransom demands inside an HTML file with the name "how_to_back_files.html". The note promises the decryption of a couple of files to prove that the hackers own a decryption tool, and threatens to up the ransom if the victim waits more than 72 hours. The full note is as follows:
