DEFCON 16 and Black Hat are security centric conferences recently held in Las Vegas where Aruba Networks provided the wireless infrastructure. In a self descriptive FAQ of the environment to be expected (quoting from the FAQ site)
Q: Is there a free network at DEFCON?
A: Yes. It would be fair to describe the network as ‘hostile’. It has been described as ‘the worlds most hostile network’, but such descriptions are just attempts at flattery. It is recommended that if you want to connect to the DEFCON network pretend that you are sharing out your entire hard drive to 5,000 hackers. You may want to bring a ‘clean’ computer that you don’t mind being infected/hacked/etc…
