Hacker Posts Code for Attack on Older Versions of IE

PCs running older versions of Microsoft's Internet Explorer browser could be at risk of a new attack, thanks to an unidentified hacker who posted attack code to the Bugtraq mailing list, reports Computerworld.


The attack affects Internet Explorer versions 6 and 7. The article explains:
