I dont want to start a lengthy debate, but I feel that I should respond
here and state for the record what my stance is.
I believe strongly in cooperating and coordinating with vendors on
security holes and doing everything possible to help them resolve a fix
without resorting to full disclosure and public exploit code (at least
until after the patch). However, it is not the responsibility of a third
party to chide and hold the hand of a negligent vendor. My time is
expensive. I have already gone to great lengths to provide you with
technical details and proof-of-concept. The code was written because I
had the time and inclination to prove a theory. Your own problems with
internal politics or agendas that prevent you from delivering a timely fix
are your own. That said, keeping the vulnerability researcher in the
loop on progress is a good way to put them at ease.
What you do not mention in your rant about me is that I requested that you
keep me in the loop and inform me when/how you would fix this problem and
I tried to give you the sense that I'd even be willing to help further if
necessary. I did not receive any email from microsoft after that time
either.
It sounds like you were willing to do this with @Stake but not me... well
thank you... should I use a non-alphanumeric character in my name next
time? Had I been treated with the same respect and participation you have
extended them, I wouldnt have been left wondering whether to release this
or not. This isnt the first time i've dealt with Micrsoft and my existing
impression of your communication skills is not a good one. If you are
indeed trying to fix this, I am glad to hear it.
As for my reasons in posting the message...
I have had more and more clients of my own moving to Windows 2000 and what
I did was definitely in their interest. This hole, as you yourself are
indicating, is known to many parties performing their own independent
research. Not all of them would have made this disclosure publicly or
to you. They may have exploited it quietly until it was found in the
wild. This is the risk that is present while users wait for a fix.
Please do not demonize me for my actions. It is MS's design that has led
to this problem. One, I might add, that MS has made before and failed to
learn from. And it would have been very easy for you to post a public
workaround
I have no reputation, (well at least not a good one) and was not motivated
in that regard. As I said before, this is a known problem to several
people, keeping it quiet (me, MS, @stake, and anyone else) was further
endangering our common clients.
All, this said, the bug really isnt all that terribly interesting anyway.
I was more interested in sharing my NTLM research with others. So, I may
have had a personal motivation, but it wasnt to glorify myself as a
'criminal hacker' as you seem to imply.
