Sometime in the past, someone thought it would be a really good idea to encrypt wireless network traffic so that others couldn't snoop on it and steal their things. There were some initial forays into the field until Wired Equivalent Protocol (WEP) came along. WEP was great, it was fast, it had a cool name, and was relatively easy to implement. The problem was that other naughty people realized that if you listened to WEP traffic long enough, you could decrypt the traffic, and furthermore, gain access to the network. Not good. Needless to say, you shouldn't use WEP anymore (though legacy systems are legacy systems, so people still do).
We are going to create a WEP network through one of a number of ways and generate some fake traffic for our attackers to watch. We're going to use Airbase, Python, and a little bit of iptables, though not so much that you'll cry yourself to sleep tonight.
