TeslaCrypt Isn't All That Cryptic

citpyrc writes: TeslaCrypt, the latest-and-greatest ransomware branch off of the CryptoWall family, claims to the unwitting user that his/her documents are encrypted with "a unique public key generated for this computer". This coudn't be farther from truth. In actuality, the developers of this malware appear to have been lazy and implemented encryption using symmetric AES256 with a decryption key generated on the user's machine. If any of your machines are afflicted, Talos has developed a tool that can be used to generate the user's machine's symmetric key and decrypt all of the ransomed files.

They could have claimed to have encrypted the documents using a slice of lemon wrapped around a hamster.

The problem with hamster-based encryption is the animal rarely survives the XOR process.

I encrypt everything with asymmetric ROT-13, you insensitive clod!
