Internet Explorer can track your mouse anywhere on the scree,even when you aren’t browsing
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 is minimized. All supported versions of Microsoft’s browser are
reportedly affected: IE6, IE7, IE8, IE9, and IE10.
Explorer can track your mouse movements anywhere on the screen,even if the Internet Explorer window is minimized. The vulnerability is
particularly troubling because it compromises the security of virtual
keyboards and virtual keypads.. And Microsoft, which was informed of the massive
potential security hole over two months ago, has no plans to fix it.
Which means that as you explore the web, the web can explore you right
back.
Internet Explorer’s event model
populates the global Event object with some attributes relating to mouse
events, even in situations where it should not. Combined with the
ability to trigger events manually using the fireEvent() method, this
allows JavaScript in any webpage (or in any iframe within any webpage)
to poll for the position of the mouse cursor anywhere on the screen and
at any time—even when the tab containing the page is not active, or when
the Internet Explorer window is unfocused or minimized. The fireEvent()
method also exposes the status of the control, shift and alt keys.
Affected properties of the Event object
are altKey, altLeft, clientX, clientY, ctrlKey, ctrlLeft, offsetX,
offsetY, screenX, screenY, shiftKey, shiftLeft, x and y.

For the data to be useful, the attacker would have to know what website
you are currently using. Given that it’s already being used by
advertisers, however, this can’t be particularly hard to achieve. They
can take note of where they place their malicious ads, and an attacker
would of course know the layout of the malicious page they design, or
the legitimate one they hijack for such a scheme.
