TeslaCrypt is ransomware that is quite different from other ransomware programs. Instead of encrypting everything on the computer, it specifically encrypts video game data such as mods, saved data, and games like Team Fortress 2, HUD Files. It asks for a payment of around 0.7 to 2.5 bitcoins to unlock the files. This program copies itself into the AppData\Roaming\ folder to activate. It targets over 180 games like Call of Duty, Minecraft, and many more. TelsaCrypt uses C++ and uses AES encryption and is similar to Cryptolocker as it uses the same message screen and photo and the icon on the desktop is called "Cryptolocker", meaning that TeslaCrypt may be a heavily modified version of Cryptolocker.
TelsaCrypt isn't as effective and cannot do real damage since it only encrypts games that one can recover easily. If the user does not pay the ransom, It won't delete boot sectors, files or important core folders. It simply affects games.
