Firefox Extension Stymies 'Clickjacking'

Posted by Susan Hall Oct 10, 2008 11:08:06 AM

As worry spreads about the "clickjacking" vulnerabilities that affect all major Web browsers, Mozilla points out that a Firefox add-on has been updated to protect users, reports Computerworld.

 

The latest version of the free extension NoScript contains a feature called "ClearClick." As Italian security researcher Giorgio Maone explains:

Whenever you click or otherwise interact, through your mouse or your keyboard, with an embedded element which is partially obstructed, transparent or otherwise disguised, NoScript prevents the interaction from completing and reveals [to] you the real thing in 'clear.' Then user can decide whether to continue clicking, or free up the mouse from the underlying -- and potentially exploitive -- content.

Adobe previously released a workaround to deal with the issue that can also be used to spy on people through a webcam or microphone.
