A couple of weeks ago, we told you that Britain's National Crime Agency (NCA) was warning against an incoming malware assault - the two-pronged GOZeuS/CryptoLocker attack.
The good news, hopefully, is that you've since tightened your digital defences. The bad news? In 24 hours, that warning expires and your sensitive financial information could be vulnerable.
If you haven't already, make sure to check out our earlier tips on how to protect yourself against the GOZeuS/CryptoLocker attack - time is now obviously of the essence.
Originally, the NCA had said that more than 15,000 UK computers were at risk. Preventative measures have now apparently reduced that figure to mere "thousands".
The NCA explains and advises:
Current indications are that UK GOZeuS and CryptoLocker infections have reduced since 2 June, but thousands of systems remain affected or at risk. By updating security software, running system scans to detect and clear infections, and checking that computer operating systems are up to date, individuals and businesses can take advantage of the criminal network's relative weakness.
In case we missed anything, here's some additional advice from Kaspersky Lab's senior security researcher David Emm:
- Don’t follow the links you received from unknown senders (by emails or in social media networks)
- Don’t download, open and keep unknown files on your device
- Don’t use open unsecured (public) Wi-Fi networks for any transactions. Use openVPN traffic encryption
- Always double-check the webpage before entering any of your credentials or confidential information – phishing sites are deliberately designed to look authentic.
- Work only with websites with the ‘https’ prefix, they are more secure than those with ‘http’
- Make sure you have up-to-date anti-malware protection installed
- Don’t forget to use the same protection when using your mobile/tablet device for transactions
Did you take action after the NCA's warning, or is it all a load of hot cyber-air? Let us know your thoughts by leaving a comment below, or consult the government's Get Safe Online portal for additional information.
