Hey everyone! I am new to this forum. I am here because the company I support was infected with the CryptoLocker virus in which a majority of their files were infected and encrypted with the crypz extension. Although I managed to restore 97% of the files from backups, 3% are still infected. I'm trying to find a decrypter that can restore the infected files back to their original state. I have tried TrendMicro's utility with no luck. I'm hoping one will be available soon.
Thanks in advance.

Any files that are encrypted with Crypt0L0cker (TorrentLocker) will have the .encrypted extension appended to the end of the encrypted data filename and leave files (ransom notes) with names like DECRYPT_INSTRUCTIONS.TXT, DECRYPT_INSTRUCTIONS.HTML, INSTRUCCIONES_DESCIFRADO.HTML, How_To_Recover_Files.txt, How_To_Restore_Files.txt and HOW_TO_RESTORE_FILES.HTML.

Any files that are encrypted with CryptXXX 3.x will have the .cryp1, .crypz or a random 5 hexadecimal character extension (i.e. ..AC0D4, .DA3D1, .73E61, .EF538) appended to the end of the encrypted data filename as explained here. However, the newest CryptXXX does not change file extensions and uses a generic file (ransom note) named "README".

CryptXXX 2.x/3.x variants will leave unique Personal ID files using random 12 hexadecimal characters with names like <id-number>.html, <id-number>.txt, <id-number>.bmp (i.e. S45CC72F3463.txt, !4AD604B8AE89.txt), !Recovery_<id-number>.html, !Recovery_<id-number>.txt, !Recovery_<id-number>.bmp (i.e. !Recovery_4582C8FAEB15.txt). Newer versions of CryptXXX 3.x will have ransom notes with names like @[id-number].txt, @[id-number].bmp, @[id-number].html (i.e. 14AC2EF20B23.txt).

A repository of all current knowledge regarding CryptXXX is provided by Grinler (aka Lawrence Abrams), in this topic: CryptXXX Ransomware Help, Information Guide and FAQ. More information about CryptXXX 3.x is provided in these news articles...There is an ongoing discussion in this topic where you can ask questions and seek further assistance. Other victims have been directed there to share information, experiences and suggestions.Rather than have everyone with individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in the above support topic discussion...it includes experiences by experts, a variety of IT consultants, end users and company reps who have been affected by ransomware infections. 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.
