KnowBe4 reports a new strain of the infamous CryptoLocker has been found. The new Trojan does not rely on the 2048-bit RSA encryption and does not need any communication with a Command & Control server to work. It operates stand-alone, and the extensions of affected files are switched to .cryptolocker after encryption.
KnowBe4 says that judging by the choice of the encryption algorithm and the method for receiving payment, this CryptoLocker variant does encrypt all the files it can get its hands on, and by preying on assumptions regarding the CryptoLocker brand name, these miscreants could still make a profit as not many users will know how to decrypt their files.
