Do you have a stat on the number of boxes with DCOM open?  Do you really
think that the number of organizations still not filtering 135 etc outnumber
those running IIS.  Yes, you can exploit this via IIS -- IF IT IS ENABLED
(read: not default).

Sure, but have there actually been any "good" worms yet?

Don't forget Nimda as well.  But seriously, does Code Red or Nimda actually
cause you connectivity issues?  I see a ton of Code Red/Nimda like traffic
on various logs and yet the effect is pretty much zero.

If your boxes are patched, Firewalls configured properly, IDS tuned and
running -- why would this new worm be so scary?  The only reason that yet
another worm is going to be scary is that people don't patch their boxes or
configure them to be "secure".  Perhaps I am missing something but I think
Code Red and the likes did everyone a huge favor -- forced people to patch
systesm, put script kiddies and consultants alike out of business.

Hell, maybe I will write one myself.   ;-)
