Good morning, I'm having troubles with a CTB-locker infected machine. All the files are encrypted with .nzelfki extension. I know it's almost impossible to recover ransomware-encrypted files, but I would be happy if someone here could help me. Both shadow volume copies and kaspersky decryptor didn't work

Unfortunately, there is still no way of decrypting from CTB-Locker. You will have to restore from backup until something comes up (such as the culprit's server being seized, which is unlikely, but the only hope).


This guide has all of the information you'll need to understand what the virus has done and why it cannot be decrypted.

CTB Locker will attempt to delete all Shadow Volume Copies when you first start any executable so that you cannot restore your files via System Restore, native Windows Previous Versions or using a program like Shadow Explorer...but it never hurts to try in case the infection did not do what it was supposed to do. You may may even be able to use file recovery software such as R-Studio or Photorec to recover some of your original files.

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.
