Cryptolocker ransomware definition
Cryptolocker ransomware is a trojan virus that targets Windows devices. Once the virus infects a computer, it searches the local storage and connected media (external hard drives, cloud storage) for files to encrypt. It then uses asymmetric encryption to lock these files and make them unavailable to users. Instead, a message is displayed, informing the user that their files are encrypted and will be destroyed unless they pay a ransom.
