Unfortunately, had to pay the ransom for a client who did not have good backups. I received the public and private keys, but upon running the decrypt.exe file, it reports success decrypting files, but the files aren't actually decrypted. Is there another program we can run to do this, particularly since we have the public and private keys (supposedly).


The original infected machine was a Windows 7 Pro machine that was so badly damaged it would no longer boot reliably. I took an image of the OS and reformatted so the client could get back to work. I have a copy of all the encrypted files (over 100GB unfortunately - it got to their server share as well). I'd hate to tell them that after paying the ransom they are still screwed.

A repository of all current knowledge regarding CryptoWall, CryptoWall 2.0 & CryptoWall 3.0 is provided by Grinler (aka Lawrence Abrams), in this topic: CryptoWall and DECRYPT_INSTRUCTION Ransomware Information Guide and FAQ

There are also lengthy ongoing discussion in these topics: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 one of those topic discussion.
