Hidden and dangerous



Online banking customers should be wary of a new series of Trojan horses out to filch financial information, according to a TechWeb article.

The Tolger line of Trojan horses, said U.K.-based security firm Sophos, target online users of a slew of British-based banks, including users of Barclays, HSBC, Lloyds, and Nationwide.

Once the Tolger Trojan infects a system, it sits invisibly in the background, monitors which Web sites are put on the browser, and if it recognizes one as an online banking site it ambushes the user by capturing keystrokes and snapping screen shots.

Periodically, that information is packaged and sent to a remote server controlled by the attacker.

Although Tolger watches for British bank access, the technique could easily be used to nab account information from U.S. institutions, which have also been the frequent target of phishing scams.
