Any files that are encrypted with CryptXXX 3.x
(UltraDeCrypter/UltraCrypter) will have the .cryp1
or a random 5-character hex
extension (i.e. .73E61, .60FCC
) appended to the end of the encrypted data filename. 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). The newest version of CryptXXX 3.x will have ransom notes with a name like @<12 hex>.txt.
You can submit samples of encrypted files and ransom notes to ID Ransomware
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.
