Thus, files are locked with double encryption.Īfter contacting cyber criminals, users are encouraged to pay a ransom to receive the key. Criminals employ one of 11 pre-generated public keys to encrypt the key generated by the AES algorithm. RSA is an asymmetric cryptography algorithm, which generates two keys (public and private ). This algorithm generates a single encryption/decryption key uniquely for each victim. AES is a symmetric encryption algorithm and is used to encrypt data. As mentioned above, XZZX employs AES and RSA encryption algorithms. The new text file contains a simple message informing victims of the encryption and encouraging them to contact XZZX's developers via one of the email addresses provided. After successfully encrypting data, XZZX places a " _HELP_INSTRUCTION.TXT" file in each existing folder. From this point, it becomes impossible to use and distinguish files. XZZX" pattern.įor instance, " sample.jpg" is renamed to a filename such as " 2333F86C00C22D4CC955649603FBD1BC.XZZX". Immediately after infiltration, XZZX encrypts stored data using AES and RSA encryption algorithms.ĭuring encryption, XZZX renames files using the ". This malware was first discovered by computer security researcher, Lawrence Abrams.
