As soon as the encryption is finished, Masok places a special text file (such as “_readme.txt“) into every folder containing the encrypted data.The message given by Masok text file asking for the ransom is definitely the same as the statements given by other ransomware virus representatives coming from the DJVU clan. It actually mentions that the information is encrypted and that the only way to bring back it is to use a a distinct decryption key. Sadly, this is definitely true. The sort of cryptography mechanism used by Masok is still not properly examined. Still, it is absolutely particular that each victim may be given the specific decryption key, which is totally unique. It is difficult to restore the files without the key available.
