I think you're right in that most vendors recognized the mathematical
problem and fixed it in a (usually) proprietary way shortly thereafter.
As far as cracking in the wild is concerned, I'm sure there are more
than a few APs out there that had WEP thrown on for the heck of it (or
because there was no choice) and never upgraded to anything more secure.
802.11i has only been ratified for a few months so the vendors are in
the process of issuing firmware revs to support it that are bound to be
buggy at first which is going to delay the market doing these upgrades
but when the security conscientious organizations out there have a way
to move to something more secure, they will.
That being said one only has to look at the number of Code Red infected
web servers, unsecured spam relays and 'owned' end stations on the
Internet to see that there are a number of people and organizations out
there that are LESS than security conscientious.
So you're right. To do WEP cracking in the wild, in a lot of cases,
will involve fairly old firmware. However, that should not imply that
there are a shortage of APs to crack that fit that description.

Just a comment on using a WEP cracking programs. I heard from Keith
Parsons
who is an expert wireless teacher saying that WEP cracking in the wild
today
doesn't exist in most cases.
In early 2002 all vendors saw the weak IV as an attack. So they changed
the
firmware to no longer support those weak IV's. If you want to crack WEP
it
will most likely be on an AP that has a firmware version prior to 2002.
Any comments on this?

You can send me a zinger if I messed up :-)
Look for a new Auditor version (looks like it will be labeled
Auditor 3) to come out in the next few of weeks. There will
be a couple of new tools.
From the author of Auditor:
"Aircrack is a better WEP cracker like Airsnort."
"The second one is named chopchop and is an active WEP
decrypting attack."
"P.S. A WPA preshared password cracker is also on the way."

For those of you using Auditor, did you donate? We did.
