When the file is encrypted people are unable to use them. Delta Plus adds the “.delta” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by Delta Plus, will be renamed into “myphoto.jpg.delta“. As soon as the encryption is completed, Delta Plus places a special text file into every folder containing the encrypted data.The message given by Delta Plus text file requesting for the ransom is definitely the same as the statements given by other ransomware representatives belonging to the Babuk type. It actually discusses that the information is encrypted and that the only way to restore it is to use a an unique decryption key. Unfortunately, this is absolutely true. The type of cryptography mechanism applied by Delta Plus is still not appropriately examined. Still, it is definitely specific that each victim might be given the specific decryption key, which is completely unique. It is difficult to bring back the files without the key available.
