A new ransomware called Enigma was discovered that targets Russian speaking countries. The Enigma Ransomware encrypts your data using AES encryption and then demands 0.4291 BTC or approximately $200 USD to get your files back. This ransomware was given this name simply because it creates multiple files with the keyword Enigma and appends.enigma to all encrypted files. The ransom note contains information on what happened to the victim’s files and a link to the TOR payment site. Sometimes the deletion of the Shadow Volume Copies are unsuccessful and they can be used to recover files.
