Trusteer researchers have uncovered a new configuration of the Ice IX malware designed specifically to steal Facebook users' credit card information.

"The new Ice IX variant displays a Web form inside a browser pop-up window when users log into Facebook," writes PCWorld's Lucian Constantin. "The pop-up is designed to appear as if it's part of the social networking website and asks users for their name, billing address, credit or debit card number, card expiry date and card identification number."

"'The attackers claim the information is needed to verify the victim's identity and provide additional security for their Facebook account,' Trusteer's chief technology officer, Amit Klein, said in a blog post on Tuesday," Constantin writes.
