Reads this if you use online banking

Ever heard of phishing? It’s the process whereby someone tries to lure you into divulging personal details, (username, password, account details etc), usually by sending you a mail that appears to come from your bank explaining that their servers are to be upgraded, and asking you to follow the link and re-enter all your details.

Well, last week a major pharming attack hit users of 65 banks in the US, Europe and Australia. Pharming is kind of a step up from phishing, because you don’t need to click on a link in an email. Basically what it does is recognise when you wype in the url for your banks site, and redirect those requests a duplicate site. In last weeks case, all the information keyed in by users was subsequently forwarded to the banks in question, which of course makes the problem harder to detect. But by the time the banks received the information entered it had already been captured by the guys behind the scam.

According to Yahoo news, target institutions included Bank of Scotland, Barclays Bank, eBay, Paypal, Discover Card & American Express.

The whole thing seems to have been launched through a trojan known as Burglar.A, which in turn downloaded a number of other Trojans. Keylog.LN, which captures keystrokes and looks for user login details, Banker.CLJ which carries out the pharming scam, FileStealer, which installs a web-server on the PC giving the authors remote control of the server, and Sters.P, designed to prevent users and programs from contacting their websites for security updates.

So overall this was a really nasty little piece of code. The Internet is a fabulous place, but to quote Hill Street Blues….Let’s be careful out there!
