Good morning.
A particularly nasty Ransom-ware Trojan called CryptoLocker which first surfaced in September 2013 has become a serious threat once again.
The ransom-ware is entering peoples email inbox's appearing to be a scanned fax. The attachment is a zipped folder and if opened it will cause serious and potentially unrecoverable damage to your IT system and data.
The email is entering inbox's with subject headers such as:
• New Fax – 3
• Scanned Fax
• Fax@your domain
The safest option is that if you receive any emails contain the word FAX in the subject header with a zip file attached please do NOT open it.
The ransom-ware is activated by the user when they click to open the attachment and in some flavour a countdown timer or Red X will appear on the screen with a message saying your data is being encrypted. You will then be presented with the option to pay a ransom to get your data back; even if you pay the ransom your data will not be decrypted!
This ransom-ware is a real threat and if your system becomes infected there is no way to decrypt your files and you will lose everything unless a backup has been made!
As the ransom-ware is arriving by email we strongly urge you to be aware of your emails and be careful when opening attachments if they are not from a source you regularly receiving emails with attachments from.
We urge all users to be incredibly vigilant when opening all attachments and if your Anti-Virus protection says that an email or the attachment may include malicious items giving you the option to open it or not please do not open it!
