CryptoLocker

What is CryptoLocker?

CryptoLocker is a ransomware variant and type of malware that targets Windows computers and encrypts files. As with other forms of ransomware, once an infection takes place, hackers demand a ransom in exchange for a decryption key. CryptoLocker first arrived on the scene in 2013. Delivered via phishing emails, hackers dupe victims into downloading malicious attachments containing Trojans. Defenses against CryptoLocker include firewalls, anti-virus programs, anti-phishing solutions, anti-malware solutions, and user awareness training.

How to prevent CryptoLocker attacks

Although there are many ransomware variants, the two most popular are Locky and CryptoLocker. Both types of ransomware are distributed through malicious email attachments and booby-trapped URLs (also usually emailed). Once the ransomware is activated, it quickly encrypts all files it can find on the device and renders them inaccessible. With the encryption complete, hackers request ransom payments for the files to be unencrypted. If victims refuse to pay the ransom or let the deadline pass, many cybercriminals threaten to delete the decryption key or raise the ransom significantly.
