Wi-Fi in the Sky

mindless4210 writes "In an attempt to have the greatest warflying run to date, members from Daily Wireless, Tom's Hardware, SoCalWUG, and Highlands Highspeed teamed up for an amazing two-plane mission around Southern California. They picked up over 3000 access points and 900 clients, established a point to point link between the two planes, and successfully video conferenced in real time over the connection. This is also the first time that the wireless network detection tool Kismet has been taken up in the air, reporting over twice as many APs as NetStumbler. There is some footage of the flight in divx format available here."

    How much information can they REALLY gather from flying overhead? I assume that those planes travel as speeds > 85mph. Given the range of most APs, and the altitude of the plane, wouldn't they only be in range for a couple of seconds?

      Actually, if it's a windy enough day, you can get your ground speed down to zero MPH. Just fly 60mph into a 60mph headwind. For that matter, if it's a really windy day, you can fly backwards.

  2. Roadtrip soon, which GPS? by Jon+Howard · · Score: 3, Interesting

    I'm going to go on a roadtrip from the East Bay heading north. My friends will be taking a second car, and we've already decided to set up a link between us for the trip (can you say deathmatch?) - but I need to pick up a pair of GPS units on the cheap. Does anyone have a recommendation for a cheap, gpsd compatible unit?

    1. Re:Roadtrip soon, which GPS? by PatJensen · · Score: 4, Interesting

      Jon, Units just need to support the open GPS NMEA protocol. USB is preferred because it can be powered by your laptop without a bulky adapter or take a lighter port. I'd recommend some of the GPS "mouse" devices that are imported from Japanese manufacturers and are on eBay for $60-$80. No display but they are great for navigating with Streets and Trips or Netstumbler, etc. They will probe as a standard serial device at 9600 baud which you can feed to your navigation software. I'm in the East Bay about every 2 weeks and I frequently run kismet there quite successfully. Using an external antenna helps a lot too! Pat

      The short answer is 'no', Radio/WiFi signals move at near-light speeds and planes do not. Any sort of 'trail' that you're thinking would be at MOST a few millimeters (if that!) and it would be only one-way, preventing any real communication.

  6. WEP (in)security assumptions by David+Jao · · Score: 5, Interesting
    The article incorrectly assumes that WEP enabled networks are more secure than non-WEP enabled networks. You can tell by the red/green color choices and the choice imprecations that the authors think poorly of un-WEPd networks. Unfortunately, in reality the best way to secure a wireless network is one that does not involve WEP. It is well known that WEP is insecure and thus one must resort to other means in order to secure a wireless network against known attacks.

    As a starting point, the WaveSEC homepage describes a way to secure a wireless network entirely using IPsec, without relying on WEP. In addition, for a small home network you can get away with static IP addressing instead of using DHCP, and in this way you can gain all the benefits of WaveSEC security without needing any software patches (since if you look closely all the software patches are DHCP related).

    IPsec is supported in Windows 2000 and up, Linux 2.6 (natively) or 2.0 and up (with Free S/WAN patches), and FreeBSD; unfortunately I have no firsthand knowledge of MacOS support. The main drawback of IPsec is that it is a very complicated protocol and takes a lot of effort to set up. Making different systems interoperate with each other is especially challenging -- for this task, I recommend the Free S/WAN interop page which links to an eclectic pile of guides covering most of the possible combinations.

    My own home wireless network is a mix of Linux and Windows XP clients all connected via IPsec, and I have much more confidence in its security than I would otherwise have with WEP.

      I was waiting for someone to mention this...

      The ONLY security WEP provides is merely delaying any would-be 'hacker'.

      Simply sit within the range of a wireless network with your laptop, collect enough packets with Ethereal or a similar tool, and you'll have the AP's WEP key.

      Proof of concept: WEPCrack, open source program for cracking WEP keys from tcpdump, prismdump or ethereal captures.

      At my school, in order to get internet access we have to authenticate against the school's proxy server. All the wifi access points have the same SSID (the ingenious 12345). So a few bright individuals create ad hoc wifi networks with their laptops with an SSID of 12345, then build a simple page with a prompt like the one the proxy gives and they harvest school id/password combos.

      Luckily, my own laptop(iBook) differentiates between normal and ad hoc wifi networks and prompts me before connecting to an ad hoc system but the ones distributed by the school don't as far as I can tell. So how does one verify that they're connected to a real AP and not some kid's laptop?

    Wait, nevermind! All of the unsecured AP's must just be Mom & Pop coffee shops offering free nodes. Right, must be it.

    While sitting at my coffee table, Kismet shows 4 wireless networks available (without an external antenna) and each of these networks has WEP enabled, the message must be getting through to some people!

    I know absolutely nothing about Microsoft's WI/FI API, but imagine a virus that spreads throughout the mess (er, mesh) created by the unsecured wireless networks. Hmm... and if the virus is smart enough to determine the WAP's manufacturer, it could even use the default admin password to blow massive holes in the router's firewall as well. While it's not very likely in my geographic location, it could definately be feasible in more densely populated areas.

    Oh, and kudos to Kismet for blowing NetStumbler out of the water!

    We had an ibook scanning as well, it picked up about 1/10th of the networks. All in all without very good equipment (knoppix, old kismet, nothing special) we got about 190 networks.

    It's possible with a good antenna to circle and get online, it's also possible to make cell phone calls if you should feel like it (not that we did that). We were flying at about 2000 feet for most of the time.

    It wasn't the last time we did it either. War flying can be fun with a GPS that records the altitude as well as the lat+long.

    Hmmm.... Wasn't this said to the Wright Brothers?? Of course, we all know what failures they turned into /sarcasm off.

    Doors pop open all the time. During flight training, flight instructors tell students what to do in the case that a door pops open. It's actually not a big deal, if you have the proper training. The air pressure keeps the door almost closed.

    Inexperienced pilots flying formation?? Do you know what kind of formation we were flying? Did you know that both pilots have hundreds of hours? The pilot of the Cherokee has a private airstrip with 5 planes and a helicopter.

    The closest we ever got to each other was about 100 feet. Most of the time we were at least 300 feet away.

    As far as the wifi messing with the avionics. Yeah there is a chance... but I did a previous warfly in December, 2003. We didn't experience any problems. Also, it doesn't really matter if the wifi messes with avionics, as we flew VFR. We followed visual landmarks, and used a moving map GPS.

    I did some research while ago, wether warwalking/wardriving is legal here in Finland. Surprisingly I found section from the radio law that states receiving transmissions that weren't intended to you directly are illegal to receive. Meaning if you don't own the accesspoint or have legal access to it, you can be sentenced with this law, and the sentence goes up to 2 years in prison. That makes warwalking pretty extreme sports if there's someone who wants to try if this law holds in court.

    Flying in formation dosen't mean you have to fly 3-4 feet like the fucking blue angles. You can fly 100's of feet from each other as long as you are maintaining the same heading, speed, and distance away from the other airplane.

    People also forget that Wireless equipment is line of sight, so by being in a airplane you can see more AP's then by driving alone, not to mention that is saves more time.

    I think it all boils down to jelousy and ignorance. These people can't own or see owning a plane, so they think that any one that does is a moron, and that flying in a plane to find Wireless AP's is a waste of time..

    If those out there have the money and the resources to fly a fucking plane for wireless access points let them do it.
