Hello Fionnbharr,

Please see my response to your comments in-line.

That Bluecoat advisory was released on 29 September 2008. What makes
you think that I did not discover the SonicWALL vulnerability/vector
and reported it to ZDI *way before* that date? Well, FYI I reported it
to ZDI in June 2008 and discovered it even before.

At least, you should consider the possibility of the attack vector
being discovered by two researchers concurrently. It can take quite a
few months before the vendor provides a patch, not to mention that
SonicWALL was VERY slow to confirm the vulnerability.

Don't you know that responsible disclosure means that the details of a
vulnerability can be held for quite a while before being released to
the public? Since when the publishing date of an advisory is equal to
discovery date?

Furthermore, it appears that Bluecoat only released their advisory
*after* the researcher jplopezy made his advisory public, which could
suggest that he did NOT inform the vendor before releasing the
details:

It's also interesting that the researcher released the advisory
(bugtraq post) one day *after* I published the general description of
the attack:

June 25th, 2008.
ZDI forwards my findings to SonicWALL (see "Disclosure Timeline"):

September 20th, 2008.
I publish the general description of the attack:
http://www.gnucitizen.org/blog/new-technique-to-perform-universal-website-hijacking/

September 21th, 2008.
Researcher jplopezy finds the same attack vector on BlueCoat's web filter:
http://www.securityfocus.com/archive/1/496577/30/0/threaded

Notice jplopezy published the bugtraq post *one day after* I published
the general attack description on GNUCITIZEN. Interesting?

Please do your homework before many any accusations.

Can't you accept the idea some some of us still consider hacking and
breaking into a system not necessarily the same thing?
