first of all I would like to introduce myself (and forgive me if it's not the right place to do so). I'm a 24 years old Italian Computer Technician and I'm currently involved with a lot of request about encrypted files. I've recently been contacted about an encryption extension I've never heard of before: .rpyxhhm


I need help to figure out if it's something that can be decrypted or if I should just give up on these. If someone can tell me where to upload an example file, I'll gladly do it.

You are most likely dealing with a newer variant of CTB Locker (aka Critroni, Onion) ransomware. Any files that are encrypted with CTB Locker will have a 6-7 length extension consisting of random characters such as these .uogltic, .mtrsxox, .phszfud, etc. This extension is believed to be generated as a result of some type of algorithm involved at the time of the initial infection.

A repository of all current knowledge regarding CTB Locker (Critroni, Onion) is provided by Grinler (aka Lawrence Abrams), in this topic: CTB Locker and Critroni Ransomware Information Guide and FAQ

Unfortunately at this time there is no fix tool and decryption of CTB Locker...is impossible since there is no way to retrieve the private key that can be used to decrypt your files without paying the ransom. The only methods you have of restoring your files is from backup, file recovery tools, or from Shadow Volume Copies as explained in the FAQ: How to restore files encrypted by CTB Locker...but there is no guarantee that will work.

As with most ransomware infections...the best solution for dealing with encrypted data is to restore from backups. If that is not a viable option, the only other alternative is to save your data as is and wait for a possible breakthrough...meaning, what seems like an impossibility at the moment (decryption of your data), there is always hope someday there may be a possible solution so save the encrypted data and wait until that time.

There is an ongoing discussion in this topic where you can ask questions and seek further assistance:Rather than have everyone start individual topics, it would be best (and more manageable for staff) if you posted any questions, comments or requests for assistance in that support topic discussion. Doing that will also ensure you receive proper assistance from our crypto malware experts since they may not see this thread. To avoid unnecessary confusion...this topic is closed.
