There were open wifi access points all over the pits. From Direct TV to access points used by reporters, it was ripe for credential theft not to mention people still using unencrypted pop3. Below are some screen shots from my iPhone running stumbler. These were collected just walking up and down the track. Sometimes people need to remember that although people who do security for a living know about these types of problems, the general public doesn't.
We should have a hamster and ferret package for the iPhone available soon.
