Security researchers have developed a tool to recover their files that have been encrypted with a ransomware program TeslaCrypt. The malware TeslaCrypt appeared earlier this year and masquerades as a variant of the notorious CryptoLocker ransomware. However, its authors seemed intent on targeting gamers in particular. Once installed on a system, the program encrypts files with 185 different extensions, over 50 of which are associated with computer games and related software, including user-generated content like game saves, maps, profiles, replays and mods. In the ransom note displayed on infected computers, TeslaCrypt claims to be using asymmetric encryption based on the RSA public-key cryptosystem. If true, this would mean that the data is encrypted with a public key stored on the system and can only be decrypted with a private key held by the attackers.
