After a several week hiatus, I take a brief look at the Cryptolocker-inspired file encrypting ransomware Cryptowall. The concept is pretty much the same, other than having the user pay through a Tor website and only in Bitcoin. Although previous versions of CryptoDefense mistakenly left the encryption keys on the host computer, this version does not have that convenience, and decryption as of now is not possible. However, Cryptowall does not affect System Restores, so restoring a previous version of a file is possible.
