MadWifi drivers have been updated to 0.9.3.1. This is really one of the only downsides of something like the BackTrack livecd. Anyone using the BT2 version will have “vulnerable” madwifi drivers unless you roll your own distro (I don’t know how) or always patch after boot (annoying). Nonethless, if you’re heading into any hostile territory (read: less formal security conference), it really is not good form to not be patched. Reading those fixes tells me it should be fairly trivial for someone to bump all vulnerable madwifi driver-using laptops off the network indefinitely.
Some random project for another year is make a more “bristly” wireless network defense drone. In other words, it would just permanently output things like beacon intervals of 0 just to dog anyone with vulnerable drivers that shouldn’t be snooping around.
