Hi, we got infected two years ago and we're now in need of the files. ID Randsomeware says it's cryptowall 3.0 - is there a way of recovering the files?

As posted in this topic "Unfortunately at this time there is no way to retrieve the private key that can be used to decrypt your files without paying the ransom on the CryptoWall Decryption Service. (You should not do this as there is no guarantee you will get your files back after payment). Brute forcing the decryption key is not realistic due to the length of time required to break an RSA encryption key. Also any decryption tools that have been released by various companies will not work with this infection. The only methods you have of restoring your files is from a backup, file recovery tools, or if your lucky from Shadow Volume Copies."

 

Anyway you have to try photorec, recuva or any good restore tools to see if you can get back some uncrypted files.

You can also share here by a wetransfer link the ransom note and 2-3 crypted files to contact you as soon as a solution will be discovered.

Kind regards, Emmanuel

A repository of all current knowledge regarding CryptoWall, CryptoWall 2.0, CryptoWall 3.0 & CryptoWall 4.0 is provided by Grinler (aka Lawrence Abrams), in the: CryptoWall and DECRYPT_INSTRUCTION Ransomware Information Guide and FAQ

Your best option is to restore from backups or as noted by Emmanuel_ADC-Soft is to try native Windows Previous Versions or programs like Shadow Explorer and ShadowCopyView if the malware did not delete all shadow copy snapshots as it typically does or try file recovery software. If that is not a viable option, the only other alternative is to backup/save your encrypted data as is and wait for a possible solution...meaning, what seems like an impossibility at the moment (decryption of your data), there is always hope someday there may be a potential solution.

There is an ongoing discussion in this topic where victims can post comments, ask questions and seek further assistance but as noted above there is no solution to fix your encrypted files. 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 one of the above support topic discussions...it includes experiences by experts, a variety of IT consultants, end users and company reps who have been affected by ransomware infections. To avoid unnecessary confusion, this topic is closed.

Thanks
