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
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

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.
