What is CryptoLocker?


What is CryptoLocker?

CryptoLocker is a ransomware Trojan that targets Windows computers and can effectively destroy files beyond the abilities of any data recovery software. The virus originally surfaced in 2013 and has since claimed thousands of victims across the world, fleecing hundreds of thousands of pounds in the process.

CryptoLocker typically disguises itself as an email attachment from a legitimate source, such as a bank, and upon download encrypts files stored on your local hard drive. This secure encryption means that files cannot be accessed or recovered without the encryption key held by the cybercriminals. The key is only provided on payment of a ransom fee, which offers no guarantees that files will be decrypted and restored.

In order to safeguard against the threat of CryptoLocker, businesses must ensure they have up-to-date Cloud Web Security installed. This software is able to detect and remove CryptoLocker, but only if it is used before any encryption occurs.

Safe backup of files via Cloud Online Backup is also recommended and computer users are urged not to click on any links from unknown sources or sources they do not completely trust.
