First off, a little back story. If you don't know what CryptoLocker is, it is a very effective piece of malware. Specifically, it is a type of malware that holds your information for ransom. Once installed in a system, it will communicate with some website to acquire an encryption key. OpenDNS and Cisco Web Security, mentioned in my previous post, can help in blocking the malware's encryption key request. When this happens, the malware will still exist on the computer, but without the encryption key, it cannot encrypt anything.
