Someone tapping into your wifi connection using Google's Glasses?

An interesting product designed by the guy who wrote that script:

Since we are discussing Google Glasses, here is a video from TrackingPoint showing the use of Google Glasses as part of their super accurate aiming system that allows the shooter to aim around corners, from behind walls, etc... all without the shooter having to expose themselves in order to aim the weapon.

First thought -- use a wifi jammer to disable such technology on the battlefield. Advantage lost. Restore it with a backup cable connection.

oh, frank? He's harmless. In the same way that all zombie skeleton jokers are harmless.

I stand in front for a reason. Not just because i'm playing some kind of super-sized trumpet, lol.

How can you concentrate with that bloke with the scary jester hat standing behind you?? Lol

[SteveRiley]

AAAAAAAAAAHHHHHHHHHHHH!!!!!!!!

[GreyGeek]

Yeah, really. The concept of 65,536 GreyGeeks makes me shudder, too! BWAHAHAHA

Greygeek mumbles under his breath: "kubuntuforums heute, morgen die Welt!" BWAHAHAHA indeed!

[SteveRiley]

No, that happened a long time ago!

Speaking of which...time to pour a gin tonic and head to bed. My funk band is playing for the opening of the Lung Force Walk in the morning. Call time is at 8:00 AM!

And on that note, here's a recent recording of us playing music from Katamari:

[Feathers McGraw]

Hehe. Have all those long flights made you go a little bit crazy?

[SteveRiley]

*shudder*

[Feathers McGraw]

(this would be 65,536 GGs.)

The program loops repeatedly through the list of APs the wireless router sees

A wireless router is a kind of access point (AP). Actually, the script is looping through the list of supplicants, the technical term for wireless devices that are associated to an AP. Overall, though, this is very cool idea. I love the sneakiness.

It uses the word "console" with the usual square brackets and forward slash. Neat! Thanks, Steve!

Glad you like it.

Not quite, MAC addresses have 6 bytes, the script only checks four of them, I presume the first four because the first three specify the organization.

True. However, to identify a Google Glass on your network you need only bytes three through six.
Google could, no doubt, change the ":24" to something else but then all one would have to do is add a case statement to the script.

In a MAC address, the first three bytes constitute the organizationally-unique identifier (OUI), which indicates the manufacturer of the network interface -- as jlittle writes. The second three bytes constitute the Network Interface Controller (NIC) and can be assigned by the manufacturing organization in any pattern it wishes. According to the IEEE's official list, Google is the owner of F8-8F-CA:

F8-8F-CA (hex) Google Fiber, Inc
F88FCA (base 16) Google Fiber, Inc
1600 Amphitheatre Parkway
Mountain View California 94043
UNITED STATES

If you base your search only on bytes three through six, you're actually missing two thirds of the Google-specific OUI, which is required to identify a Google Glass. So the search must include these three, plus the fourth byte. And you are correct, Jerry, that Google will need to change this once the range 24-00-00 through 24-FF-FF is exhausted (this would be 65,536 GGs.)

So you want to know if a Google Glass has entered your network? Watch for Mac addresses that start with F8:8F:CA:24.

...looking for the GoogleGlass MAC address,
which is apparently the same for all of them!...

Ah, thanks for that, I missed it. So if they connect again, they'll be disconnected the next time the script loops. Neat!
