Satan is a ransomware virus, having its own web service (Raas). Once infiltrated, it denies access to files using RSA-2048 and AES-256 encryption protocol. Each encrypted file is appended with .stn extension. Satan ransomware further places HELP_DECRYPT_FILES.html file on the desktop. The message reads, that victims must pay the ransom to decrypt data, otherwise they will be unavailable forever. At present, there is no tool capable of decrypting files affected with using RSA-2048.
