What Does CryptoLocker Mean?

CryptoLocker is a Trojan ransomware that allegedly encrypts files on an affected system and demands ransom for recovering the data back. It first appeared on the Internet in 2013 and was targeted at Windows-based computers.

Techopedia Explains CryptoLocker

CryptoLocker spreads by way of compromised email attachments or through a botnet. Once downloaded and activated, it looks for certain file types to encrypt using RSA public key cryptography and then sends the private key to some remote servers. It then demands the system owner to pay a ransom in order to decrypt or recover his/her affected files; failure to do so will result in losing the private key.
