Microsoft has confirmed that every version of Internet Explorer, from version 6 dating back to 2001 up to 10, released this year, is vulnerable. Microsoft has also stated that there are no immediate plans to patch this vulnerability in existing versions of the browser. All a hacker needs to do is, buy a ad space on any webpage and wait until a user visits it. If the tab remains open, the hacker has continuous access to user’s mouse movements. Cyber Criminals could use the technique for monitoring mouse movements used to log into sensitive websites with virtual keyboards similar to those on smartphones.
