Decaf adds the “.decaf” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Decaf, will be renamed into “myphoto.jpg.decaf“. As soon as the encryption is finished, Decaf places a special text file into every folder containing the encrypted data.The message given by Decaf text file requesting for the ransom is absolutely the same as the statements given by other ransomware virus representatives. It literally mentions that the info is encrypted and that the only way to restore it is to use a an unique decryption key. Unfortunately, this is absolutely true.

Still, it is definitely specific that each victim might be given the specific decryption key, which is totally unique. It is impossible to bring back the files without the key available.
