Yes in some ways. But the there were major points brought out at DefCon
about this which got really stirred up. It was by far the best
presentation I have ever seen.
For those of you who did not attend Defcon or Raven Alders last minute
"modified" speech due to Mike Lynns situation, she brought up some great
points. The speech was great and stirred many emotions in the room.
1. The current exploit was patched in April. However, Cicso did not
disclose the bug. They told everyone including the ISP's to upgrade
immediately. Why? Oh just trust us. Many people did not upgrade because
they didn't see the urgency. You can't just hand out patches and say
2. While this one particular exploit was fixed, the main basis of the
danger is still in IOS for future exploits. Basically it is how Cisco
IOS runs and handles router crashes etc... At least that is what I
gathered. This is what Cisco does not want us to know. It brings a new
level of attack on Cisco products world wide, including a major
percentage of the internet backbone itself.
One of the things also brought up by the community is, that first of
all, Mike Lynn obtained this security flaw from a Chinese web page when
he had it translated into English. It is rumored that this developed
from earlier code leaks from Cisco. It was already out there and
exposed! He just researched it from the information he already obtained.
How can you violate disclosure on something that is already out there?
I'll also post a few quotes from Raven. I pulled them from
"Alder then blasted Cisco for going after Lynn.
" "Cisco, you are really screwing up," she said, followed by a round of
applause. "Suing researchers is not going to make you secure. Alienating
the security community is not going to encourage people to come to you
and report problems and work with you." "

Michael Lynn's presentation "The Holy Grail" is all over the net. I'm
not a Cisco guy so excuse me for asking a stupid question. Does the
presentation actually have enough details in it for the script kiddies
and other nasty humans?
