Cracking WEP with Ubuntu (or use WPA2 now!)

Anyone that still allows WEP-based authentication/encryption might
want to read this and then get with the program and disable WEP and
enable WPA2 or something a bit more modern.

This is a blog entry from some guy that was new to ubuntu and knew
little about it, yet managed to set up and use a cracking tool with
only two days futzing around. This should be a wake up call for
anyone still using WEP.

I'm surprised it took him that long. I recently saw a teenager with no
special skills do it in less than 2 hours from a cold start.

The first time I tried to install DD-WRT, I turned the router into a
brick. The problem was that one couldn't go directly from Satori to
DD-WRT. It took about an hour to de-brick the router and restore the
original Linksys firmware. I then tried to install DD-WRT again and
managed to partially corrupt the firmware by not waiting long enough
after the web page said it was done. I eventually discovered that one
has to wait about 3-5 minutes AFTER the "continue" message appears to
be sure that everything is correctly flashed. I was able to de-brick
it with tftp this time. I've also discovered that it is sometimes
necessary to power cycle the WRT54G after a flash update.

Since then, I repeated the exercise by installing the wrong firmware
flavor which was easily fixed by tftp again. I've also experienced
general weirdness when I forgot to reset everything to defaults after
going from Linksys firmware to DD-WRT. I think this is now automatic.
Anyway, it's quite as simple as the article suggests.

At this time, I could do the entire process in about 10 minutes which
is one of the benefits of Learn By Destroying(tm).

Oops. This is what happens when I try to write more than one message
at a time and accidentally end up commenting about the wrong URL in
the wrong message. Just ignore what I wrote.

I think this must be the sort of thing that another thread commentator
was referring to when he didn't much want to do the DD-WRT bit to his
gear.

I can't say I blame him...

At this time, I can't say I've destroyed the gear I'm trying to make
perform, but it's tempting!

Of course, I wouldn't have learned anything other than that they didn't
work...
