Glenn,

You had asked what I thought about the malware exploit for IE (XPsp2) and I
said I thought it was lame because it required the user to drag and drop
stuff. Well I was wrong, read this new version description.

----------------------

Most people i talked to consider the drag and drop vulnerability found by
http-equiv not as a serious problem, because it requires some user
interaction and the press pushes this topic way to much as the "first
security problem in SP2". In an article on BetaNews even Microsoft
claims it's not a high risk for customers
(http://www.betanews.com/article/1093035994).

To proof it's not a "hype" created by the media or companies like
secunia, i created another proof-of-concept based on http-equiv's code that
hides both the image to drag and the local folder you drop it to. As a
result using the window scrollbar will install malware in your startup
folder.

A little 5x5 pixel "drop zone" will automaticly follow your
mouse. Just drag the window scrollbar as usual (and a hidden image at the
same moment) and whereever you release the mouse button you will drop an
exe file to your shell:startup (as long as you remain inside the browser
window of course).

Dragging the window scrollbar is a common behavior - even if i can't
believe there was a world before mouse wheels. A common user will probably
don't recognize the installation at all.

Speaking of behaviors: If service pack 2 is installed you can work around
this vulnerability by disabling "binary behaviors" in the new IE
activex settings. You don't need to disable scripting completely.

It took me only 20 minutes to create this, so script kids around the world
with enough free time will create even better protected mechanisms to
exploit this bug in the near future.

Take it serious!
