1. Rannoh Decrypter
Although it is often difficult to reverse-engineer sophisticated ransomware variants, Kaspersky Lab made that happen, and in this case updated the Rannoh Decryptor, which now cleanses both Rannoh and CryptXXX malware. One caveat: It will only decrypt as long as there is at least one original file sample that has not been encrypted by CryptXXX. The Rannoh Decrypter now works on CryptXXX versions 1, 2, and 3. For versions 1 and 2, Kaspersky Lab found implementation mistakes, and for version 3 it was stored on the server. Follow this link for more information.
