What Is Lorenz Virus
Lorenz is the name of a dangerous ransomware infection, whose main purpose of the activity is to convince victims to pay ransom to get their files to work again. The main idea of this ransomware virus is to get users to pay ransom in the form of BitCoin to the cyber-criminals behind the virus. To do this, the Lorenz virus locks the files using an encryption algorithm which makes the decryption available only if you have a specific decryptor. The .Lorenz.sz40 file extension and the HELP_SECURITY_EVENT.html note are added after encryption is complete and they are created in order to extort victims to pay the ransom, providing them with instructions on how to do that.
