That of course, depends on your perspective.  I can't remember who but I
remember someone commenting on writing a worm that exploits IIS, installs
Apache, then removes IIS.  ;-)  

What I meant by "good" was more from the interesting and wow effect.  To me,
at least the worms are forcing people to patch boxes.  Yes, I understand
that admins are busy but come on -- we have battled with patching boxes as
long as I can remember -- when are people (not just admins) going to catch
on that this is important.  No one is going to change the fact that we have
insecure code.

I really should do some bandwidth analysis on a few networks but I never
really thought the Code Reds and Nimdas of the world were that intensive.
Sapphire for that matter, did cause bandwidth issues, especially for those
who were not patched.  So you point is well taken.

In relation to the Code Red traffic I see a ton of -- I do believe that the
effect is at least next to zero.

I understand that admins are busy people -- I used to be one.  But in
reality are there that many boxes still out there with the ports required
for exploitation open?  Again, I should probably put my beer down (but its
almost Vegas week) and do some actual research.  I am fully aware that you
can exploit this over IIS if it is enabled.

Paul, if I haven't gotten on your list of true assholes yet I am not trying
hard enough.  I would have thought that I got there years ago.  ;-)
