Ever seen WebX? - it's like PCAnywhere, or VNC or TimbukTu, only it works over the web. A user just goes to a web page, and a user at the other end can take over their machine because IE allows such software to run!
Ok, at least WebX is a commercial product designed to provide tech support, and asks if it's ok to allow it, but if it's technically possible to do it for legitimate reasons, it's technically feasable to do it for rogue reasons too.
IE first checks that the software is digitally signed, and then asks the user do you want to run this software signed by so and so. Then IE allows it to run. You do not just go to the web page. You go to the web page and IE asks if this is OK. Of course there are lots and lots of web pages that say "Hey, click here to view me naked -- just click yes to all the stupid dialogs that come up" --digsig James A.
