As for the list of domains..........................would you click on them?
I'm an "analyst" now in the company.. So i play in the LAB more.. Anyway I've proposed "closed" approach where everything is closed by default and opened as needed. So these sites are way beyond accessible..

As for clicking on them;

I have 2 VM's running XP and Vista with Office 2003 and 2007 (sp 1 and 2 on second vista machine) running IE8 .. I'm recording network traffic and processor execution.. I suck at all of this but i'll be taking all of this data to someone who will explain and in a way make me understand how these site's exploit ..
