It appears that over half a million victims of Cryptolocker can now recover files encrypted by the malware without paying any money to the cyber crooks.
Earlier in the year law enforcement agencies and security companies seized a worldwide network of hijacked home computers that was being used to spread both Cryptolocker and Gameover Zeus.

UPDATE: This database is no longer active.
