We are always monitoring IT community message boards and mailing lists for prior warning of potentially dangerous malware attacks on our network.
We are currently aware that organisations have been targeted by malware known as CryptoLocker. Users will see a tracking notice from a shipping company such as FedEx, UPS etc. either through email or social media and as it looks from a legitimate contact, open it. They are then infected by malware which encrypts files, stops software from running and corrupts documents. If you are in doubt of the validity of an email – delete it.
