What is TeslaCrypt

TeslaCrypt is very dangerous encrypting virus and ransomware. It uses AES encryption to encrypt sensitive user files (documents, photos, music, video). After this it asks for a ransom to decrypt those files. One of the features of TeslaCrypt ransomware is that it also affects gaming files of most popular games (MineCraft, StarCraft, World of Tanks, World of Warcraft). TeslaCrypt modifies encrypted files extension to one of this:

.ecc, .ezz, .exx, .xyz, .zzz, .aaa, .abc, .ccc

It will also modify desktop background to the picture with written instructions to pay the ransom and decrypt the files.
