Ouroboros ransomware has been around for more than a year in various forms, operated by different cybercrime groups. Ouroboros, known to spread via Remote Desktop Protocol bruteforce attacks and deceptive downloads, has claimed a significant number of victims worldwide. We’re now happy to announce the availability of a new decryptor that can restore the .Lazarus, and .Lazarus+ file extensions to their original, unencrypted form.
Please note that this tool only works for the Lazarus and Lazarus+ extensions. The .Kronos variant is still under analysis.
