NW3C has prepared a threat advisory brief to provide information for criminal justice agencies about Crypto Locker 2.0 Ransomware. The brief includes background information, as well as instruction on how to protect computer systems against this threat and recover from it, if affected.
Crypto Locker is a malicious virus that encrypts files and then demands a ransom to unlock them. Basically the encryption makes the files unreadable until a correct decryption key is used. The scammers demand a ransom from the victim in exchange for decryption of the files. If the payment is not made in a timely manner, usually about two days, the malefactor threatens to destroy the decryption key, which would, in effect, wipe out the user’s files.
To protect your computer system from this virus, it is of paramount importance to create and maintain a backup of all files. Any agency with an adequate copy of its files will not have to give in to the demands of the scam artists since it will be able to restore files from the protected backup.
