CryptoLocker Malware

What is CryptoLocker?
CryptoLocker is a malicious program that when installed will encrypt important files and documents on your computer making them unusable, and then demand payment to restore access to them. Once your files have been encrypted by CryptoLocker they are not recoverable by any means other than paying the money demanded. Even if you do choose to pay there are reports that the decryption process does not always successfully work.

How does CryptoLocker get installed?
CryptoLocker is usually installed through email attachments disguised as PDF files, the emails may come from any source including people known to you, but usually look as if they are from legitimate companies regarding a customer service issue, opening the ‘PDF’ file will install CryptoLocker.
CryptoLocker can also be installed through previously installed Malware via the Java 6 vulnerability.

How do I know if my computer is infected with CryptoLocker?
Your computer will display a message saying that your files are encrypted and give instructions for obtaining a key to decrypt them, payment is usually $300 (£185).
