Free decryption keys for CryptXXX Ransomware

BleepingComputer has long been working on helping users effected by CryptXXX Ransomware. This week, they published an article uncovering a bug on the CryptXXX ransomware’s payment server where victims are logging in and receiving their decryption key for free.

Free Decryption Key

These free keys are only being offered for certain versions of CryptXXX, namely those that add the .Crpyz and .Cryp1 extensions to encrypted files.

Though it is unknown why this is occurring – Bleeping Computer suggest it is a malfunction of the payment server- a detailed list of keys are available.
