An urgent national alert was issued by the UK’s National Crime Agency about a mass spamming event which has targeted 10 million UK based email users. The users receive spam emails that appear to be from banks and other financial institutions but are loaded with the malware called CryptoLocker which encrypts the files on a users computer and then demands ransom money to restore access to the files.

CryptoLocker Ransomware demands $300 to decrypt your files

The emails come with attachments looking like voice-mail, fax, or invoice files or details of suspicious transactions prompting users to click them for more information.  Doing so launches the CryptoLocker ransomware hiding within the file which then encrypts all the files on your computer and demands 2 Bitcoins in ransom to acquire the key to decrypt the files.  2 Bitcoins are worth around £536.

"We are working in cooperation with industry and international partners to identify and bring to justice those responsible and reduce the risk to the public."  Commented Lee Miles, Deputy Head of the NCCU.


Bitdefender Labs,an antivirus company, found during the week beginning Oct. w7, more than 12,000 computers were infected.  The UK crime agency advises not to pay the ransom warning there was no guarantee the encryption key world be handed over.  Anyone whose computer is infected should report it to www.actionfraud.police.uk.

Always remember to back up all your files and never open an attachment in an email unless you know the source.  Even if it looks legitimate and shows a valid url in the from address of the message you can always check the email header which will reveal the actual domain the message came from.  From Address’s in email messages are easily spoofed by hackers.
