When the file is encrypted people are not able to use them. Lorenz adds the “.Lorenz.sz40” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by Lorenz, will be renamed into “myphoto.jpg.Lorenz.sz40“. As quickly as the encryption is completed, Lorenz places a special text file into every folder containing the encrypted data.The message given by Lorenz text file asking for the ransom is absolutely the like the statements given by other ransomware representatives belonging to the sz40 type. It actually points out that the information is encrypted which the only way to restore it is to use a an unique decryption key. Unfortunately, this is absolutely true. The kind of cryptography mechanism used by Lorenz is still not properly examined. Still, it is absolutely certain 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.
Another trick of Lorenz is that the victims cannot get to the key. The key is kept on a specific server run by the frauds related to Lorenz ransomware. To get the key and recover the important information people need to pay the ransom.
