Rare Malware Only Targets Firefox


One of the advantages with Firefox that has helped it move up in market share is the perception of a more secure browser over Microsoft's Internet Explorer. Whether or not IE has managed to level the security playing field is a topic for another post, but there's at least one new piece of malware specifically designed to go after just Firefox users.

Researchers at BitDefender discovered the nasty piece of code, which they're calling Trojan.PWS.Chromelnject.A. According to Viorel Canja, the head of BitDefender's lab, the new malware resides in Firefox's add-ons folder and uses JavaScript to harvest financial information.

"Trojan.PWS.ChromeInject.A filters data sent by the user to over 100 online banking websites," BitDefender warned in a press release. "The banking websites include: bankofamerica.com, chase.com, halifax-online.co.uk, wachovia.com, paypal.com, and e-gold.com."

One the malware identifies one of the websites, it records the user's login information and forwards it along to a server in Russia, and not for safe keeping.
