Trojan can grab extra personal banking dataSeptember 27, 2008 – 7:59 AM
A Trojan horse program now available to a growing number of fraudsters can add data entry fields to legitimate online banking sites and entice consumers to give up sensitive information such as bank card numbers and PINs (personal identification numbers).
The Limbo malware integrates itself into a Web browser using a technique called HTML (Hypertext Markup Language) injection, said Uri Rivner, head of new technologies at RSA Consumer Solutions, a division of EMC. Because it’s so closely integrated in the browser, it can operate even while the user is at the real bank site and can actually change the layout of that site, he said.
“Nothing tells you that something is wrong here, with one exception: You’re being asked to provide some information that you were never asked to do before,” Rivner said during a briefing for reporters and analysts earlier this week. “If you are convinced that you are now communicating with the bank, the fraudsters can get away with anything they like.”
Limbo can get onto a user’s computer through many paths, including both pop-up messages that ask you to download an add-on program and methods that are invisible to the user, he said. They sometimes get on to PCs in conjunction with other phishing attacks.
