Jon and I didn't discover a serious general 802.11 flaw, thats is
where alot of confusion around this issue comes from. We discovered
that in general 802.11 drivers didn't malformed frames very well. The
flaws that were discovered (there were far more than one) were
specific to certain types of chipsets (atheros, broadcom, etc...). As
far as the articles go I didn't write you. If you look at mine and
Jon's quotes in each article you will see something along the lines of
"this is a systemic problem that affects the entire industry".

As far as when we used a third party card for the video demo. Alot of
Mac fans were very upset and felt that it wasn't fair because nobody
uses a third party card. That was the entire point of the demo. If we
had to do it live and someone got a copy of the working exploit we
didn't want it to be in something that actually affected anyone. As
far as confirmation you will see we never confirmed publicly which
vendors were affected. And once again I never said I wanted to stab
the mac community in the eye, I said that about the actors in a
commerical.

As a side note I have to mention the statement that Secureworks issued
clarifying the video. She forgot to mention to reporters that
statement was created in cooperation between Apple PR and Secureworks
PR. Although Apple PR really wanted the statement to be extended to
cover any demos given in person (Krebs, anonymous Blackhat employee)
Secureworks couldn't do that. Minutes after this was posted Lynn Fox
started pitching reporters a story that Secureworks had changed its
story based on the update. If you actually read the Secureworks
statement it just covers the video and says nothing I didn't say in
the video twice. I suppose her omission of this information was
designed to make it appear Jon and I were frauds and thus make a big
story. I suppose the headlines "Apple asked Secureworks to clarify
their video, Secureworks obliges" would not have been as sensational
or given the Mac zealots ammunition to drag Jon and I through the mud
for months. I also find it funny the only real news outlet that ran
the Secureworks changes position story was Macword. Here is a funny
note, the guy who wrote the story, Jim Dalrymple never contacted Jon,
myself, or Secureworks for any reason during the entire fiasco.
It doesn't matter much to me anymore as I have yet to met a client of
Errata Security (the company i formed after leaving Secureworks) that
thinks I faked it all. Also I am in the process of writing a book
about horror stories of when responsible disclosure goes wrong with
Apple being the flagship issues. Everything that happened will be
detailed. As far as security research into Apple I haven't done much
else in the last few months and I flat out refuse to report any issues
to Apple security anymore because of two things. One is that i don't
trust their PR department not to try and smear me again, i feel that
their handling of the Secureworks statement pretty much proved this.
The second reason is simple: Apple apparently has more leaks than a
sinking ship. How do I know this? Several of the bloggers who were
calling for my head on a platter had information I had given to just
one person at Apple and that no-one else knew. Its almost like pro-mac
bloggers have a hotline to the 2 or 4 person security group at Apple.
If a company wants me to keep details of a vulnerability private, they
can at least do the same.

So what is the take away from this? It was a very poorly handled
situation by everyone involved, except Jon. Jon had no real control of
any of this and in the end I realized I didn't either. I lost all
control when I allowed marketing people to make decisions about
vulnerability disclosure. However I did make some mistakes. I should
have never talked to a reporter about something we were not ready to
make public. I should have realized Apple would have responded the way
they did and just dropped full details of the exploit or not said
anything at all. With that being said I have never been a fan of full
disclosure, and I am still not, unless its a vendor that has acted in
bad faith.
How could it have been handled differently by Apple? I have reported
alot of vulnerabilities to alot of vendors and never once have I had
the PR department respond to something. Take the Dell and Toshiba
Bluetooth stack issuse. We reported it to security, we worked with the
engineers to fix it (and strangely information we gave to the
engineers didn't end up on blogs), and only after everything was fixed
(the process took about a month and a half) did we talk to their PR
group to coordinate a joint release.

With all this being said I am shopping for a new TV to make best use
of my new Apple TV. I write this on a new Macbook Core Duo 2 while
listening to my ipod play an audiobook (World War Z) that I bought
from iTunes. If you didn't know better you could also say I am a
walking commercial for Apple.
