Cross browser javascript vulnerability

It sounds like this vulnerability would take a great deal of user interaction, but cio-today is reporting on a browser vulnerability that affects pretty much every javascript enabled browser. According to Symantec …. “This issue is triggered by utilizing JavaScript ‘OnKeyDown’ events to capture and duplicate keystrokes from users,” and is a way that the attacker could scrape/log things that are typed in (bank information, passwords, etc.) Also, they say “In one scenario, a crafty programmer might be able to trick users into entering personal data into a seemingly secure field on an online payment form, giving the hacker access to anything typed within the field.”

They say it would take a fairly determined attacker and require LOT’s of typing from the user. So, sites that would require LOT’s of user input might be targetted.
