CryptoWall is a file-encrypting ransomware program that was released around the end of April 2014 that targets all versions of Windows including Windows XP, Windows Vista, Windows 7, and Windows 8. The media is commonly confusing CryptoWall with the CryptoLocker infection, when it is much more similar to the CryptoDefense ransomware. The most apparent similarity being that CryptoWall's Decryption Service is almost identical to the one for CryptoDefense. In October 2014, the malware developers released a new version of CryptoWall called CryptoWall 2.0.
