An anonymous reader writes "A new Internet Explorer vulnerability has been discovered that allows an attacker to track your mouse cursor anywhere on the screen, even if the browser isn't being actively used. 'Whilst the Microsoft Security Research Center has acknowledged the vulnerability in Internet Explorer, they have also stated that there are no immediate plans to patch this vulnerability in existing versions of the browser. It is important for users of Internet Explorer to be made aware of this vulnerability and its implications. The vulnerability is already being exploited by at least two display ad analytics companies across billions of page impressions per month.' All supported versions of Microsoft's browser are reportedly affected: IE6, IE7, IE8, IE9, and IE10."
