Computer security experts warned yesterday of another new Internet threat that can steal the passwords and account information of people who bank online -- the second such discovery in a week.
Users can pick up the latest bug, which doesn't yet have a name, from pop-up ads that secretly download software capable of capturing their keystrokes. The pop-ups originate at Web sites that receive their ads from certain online ad services, which apparently had themselves been hacked to spread the malicious code.
The bug targets users of Microsoft Corp.'s Internet Explorer browser. Experts said users can protect themselves from the bug by using a non-Microsoft Corp. browser or by using software to block pop-ups.
