The team found approximately 370 networks, and about a third of those were unsecured. In addition to that, the project managed to show how trusting the local law enforcement agencies really were: 'Near the end of the operation, a Las Vegas Metropolitan Police cruiser drove by the parking lot to see what was going on. Hill and his team waved. The police officers waved back and drove off.'"

Yes, ours is "unsecured". It gets you to a DNS which answers only one query and an "internet" where the only thing that you can send to is an IPSEC VPN server. Much good may it do you. DefCon should concentrate on real security (is IPSEC as good as OpenVPN or does it's over-compexity make it more vulnerable) and not messing around with pretending to secure your wireless with WEP/WPA and all the other hop by hop garbage.

My thing is i don't understand why people don't just make unsecured wifi routers that firewall one user from another. That way, you can get on the internet from it, but it's much harder to hack others on the same segment.
Re: (Score:3, Informative)
Easy. Don't allow traffic between any IPs behind the router, other than TO the router itself.
This is trivial with Iptables.
That would force users behind the router to connect via its external NIC to talk to each other, and that can be filtered easily as well.
You can't really spoof a machine on your own subnet.

More to the point about finding unsuspecting piggybackers, I don't see how it should be expected that the law should get involved to quickly unless a serious crime has been committed. I find this particularly alarming:
So they'd prefer if the police stopped and strip search everyone doing something they considered suspicious? What kind of hackers are they if they think authority needs to always get up close and personal with anyone doing anything remotely out of the ordinary.
It's a good thing that the police had a look, could see that a crime wasn't being committed, and decided to continue looking for something worthy of their time, not a bad thing as the absurd summary seems to suggest.

The summary only mentioned the police drive by, not the hotel's assertion that police concern was a primary factor in disallowing the balloon launch, which is what makes the complete lack of concern at the end ironic, and therefore worth mentioning.

You make a good point, however I guess I would ask why any rational society would expect just those two modes of operation. Neither seems that useful. Wouldn't it be more logical to expect either the police to come over and say hi, or to take a note of the registration and car details (not necessarily visibly)? A standard social engineering technique used time immemorial has been to look as though you should be somewhere. Only an idiot looks suspicious, and it's not the idiots who should concern the police the most.
In the first case, it's basic community policing 101. You don't prevent crime by looking intimidating, you prevent crime by being aware of what's happening and understanding why. The second option also works on the premise of being aware, but looks for standard social engineering practices and patterns, rather than cause-and-effect.
In neither case is flipping out a productive or useful method. It doesn't help you recognize where or when problems are likely to occur, and only helps you catch the more dysfunctional criminals who are likely causing the least of the social headaches. However, it is by far the most common method used, because it's easy. Catching competent criminals is much harder, much more expensive, and gives a police department a worse score on offenses dealt with.

Agreed. The statement in the summary "...the project managed to show how trusting the local law enforcement agencies really were..." infuriates me. Police are not supposed to be harassing people left and right, trying to uncover illegal or just unsanctioned activities. The police were friendly, waved, and didn't bother to investigate something that by all rights did not look overtly illegal. They acted appropriately.
I would much prefer that law enforcement err on the side of trust and friendliness. This probably means that some fraction of illegal actions will go undetected and unpunished (note that only a small fraction of those illegal actions are truly dangerous and unethical)... but that is the 'price' of freedom.
Again, I applaud the police for not flipping out when they see people engaging in activities that they don't exactly understand (but for which there is no evidence of illegal action).

Are there really people stupid enough to think that awareness of security holes is something new? Every major piece of infrastructure over the last century has had major security holes. But rather than gleefully exploiting and exposing them for personal fame and fortune, the people who figured it out just shut up about them. Why? Because they understood that fixing those holes would be costly and intrusive, and it would ultimately still not make the system really safe.
So, if you enjoy body cavity searches, universal surveillance cameras, automated defense systems, and dealing with proprietary and intrusive access controls everywhere you go electronically or physically, then go ahead and keep wardriving and warballooning and defconnning.
Just be aware that it is your actions that are bringing us the police state, because once a bunch of geeks stands up and says "hey, your infrastructure isn't secure and we are at risk", then politicians and lawmakers have to act.

You say that like it's a bad thing. Most WiFi networks are of such low power to render them effectively useless beyond a few feet of the origin of the signal. In my neighborhood with houses on half-acre to acre lots I can detect half a dozen networks. A couple are 'insecure,' but the signal is one bar in strength. Besides, I'm detecting them with my own network, so why do I want to 'steal' their bandwidth? Mine is faster. There aren't many people who want to cruise the neighborhood looking for unsecured signals so they can use their laptop in the privacy of their own automobile to surf the net. How uncomfortable is that? I surf with my feet propped up, a beer on the table, and the dog curled up at my feet.
Then there are those networks that are intentionally unsecured. The local library has a router intentionally pointed at the parking lot (Gasp!) In the downtown area every hotel is within range of an unsecured network. They even have a placard that tells you how to connect--free!
Sure, there are probably guys into taking advantage of you if your network is unsecured. Perhaps the issue is more prevalent in an apartment house or a dorm than single family residences, but I think this is more of a theoretical issue than a practical one. You can hypothesize your way to wild conclusions, but in the end, is this REALLY a serious problem?

In the UK, all BT Openworld public access hotspots are unsecured as well. You can't actually use them though, unless you log in as they have an HTTP intercept until you log in.
Unless they can differentiate between intentionally open public hotspots in Starbucks (etc) and unsecured home access points in naive people's houses, then any figures are totally meaningless.
