Once the file is encrypted people are unable to use them. Doydo adds the “.doydo” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Doydo, will be renamed into “myphoto.jpg.doydo“. As soon as the encryption is finished, Doydo places a special text file into every folder containing the encrypted data.The message given by Doydo text file requesting the ransom is definitely the same as the statements given by other ransomware virus representatives belonging to the Babuk clan. It actually mentions that the info is encrypted which the only way to restore it is to use a a special decryption key. Sadly, this is absolutely true. The kind of cryptography mechanism used by Doydo is still not appropriately examined. Still, it is definitely certain that each victim may be given the specific decryption key, which is completely distinct. It is difficult to bring back the files without the key available.
Another technique of Doydo is that the victims cannot gain access to the key. The key is kept on a specific server run by the frauds related to Doydo ransomware. To get the key and recover the important information people have to pay the ransom.
