Aplicación que no responde: iexplore.exe, versión 8.0.6001.17184,
módulo que no responde hungapp, versión 0.0.0.0, dirección
que no responde 0x00000000.

In ie 8 i have surprised, because if we open the exploit localy from the desktop for example ...
and we allow the activex warnnig and allow popups , iexplorer opens a window with the content
of c:\ .

i have surprised because the url(location.href) relative in the exploit wen we open from desktop
is C:\documents and settings\YOUR_USER\desktop\browser_die.html
so why explorer opens a window with c:\ .. this is a incorrect location.href location....

and open the exploit in a new safari window with the exploit an click in the button,
safari opens a few popups , and aftter close all popups and close
too the first window what open with google :O
