A few years ago we were hit with, what I believe is Cryptowall 3.0, has a HELP_DECRYPT file, ran it through a scanner and said it was either CryptoWall 3.0 or Crypt0. Tried a Crypt0 decrypter and it didn't work.
Back then we paid the ransom, decrypted our files. Now three years later it's surfaced there was a whole folder that got missed and we didn't decrypt it. So the problem is that I still have the private and public keys provided to us when we paid the ransom, however I no longer have the actual .exe file that does the decryption.
Is there either 1) A place I can download that exe file so I can run it with the key files I have to get these files decrpyted? or 2) Some utility/command/etc I can run that would decrypt the files manually using this private and public key?
