NSA Technology Goes Open Hardware

May 2, 2014 by Will Sweatman 27 Comments

When [Edward Snowden] smeared the internet with classified NSA documents, it brought to light the many spying capabilities our government has at its disposal. One the most interesting of these documents is known as the ANT catalog. This 50 page catalog, now available to the public, reads like a mail order form where agents can simply select the technology they want and order it. One of these technologies is called the Sparrow II, and a group of hackers at Hyperion Bristol has attempted to create their own version.

The Sparrow II is an aerial surveillance platform designed to map and catalog WiFi access points. Think wardriving from a UAV. Now, if you were an NSA agent, you could just order yourself one of these nifty devices from the ANT catalog for a measly 6 grand. However, if you’re like most of us, you can use the guidance from Hyperion Bristol to make your own.

They start off with a Raspi, a run-of-the-mill USB WiFi adapter, a Ublox GY-NEO6MV2 GPS Module, and a 1200 mAh battery to power it all. Be sure to check out the link for full details.

Modified E-ZPass Detects Reads Far From Toll Booths

September 16, 2013 by Adam Fabio 54 Comments

Def Con speaker [pukingmonkey] has spent quite a bit of time studying methods government and law enforcement use to track private citizens’ vehicles on the roads. One of the major tracking methods is E-ZPass, an electronic toll collection system used in several states around the country. [pukingmonkey] cracked open his E-ZPass tag to find a relatively basic circuit. In his DEF CON presentation (PDF), he notes you shouldn’t do this to your own tag, as tags are legally not the property of the user.

The tag uses a 3.6 volt long life battery to operate. When idle, the tag only draws 8 microamps. During reads, current draw jumps to 0.3 mA. Armed with this information, it was relatively simple to add a current detecting circuit that outputs a pulse on tag reads. Pulses are then fed into a toy cow, which lights up and “Moos” on each read.

A Suitcase For All Your Wardriving Needs

June 12, 2011 by Brian Benchoff 39 Comments

[Corrosion] sent in a tip about the Weaponised Auditing Response System he built inside a suitcase that, “has all the tools (and then some) for a wireless assault”.

The WARS is equipped with two WiFi adapters and two bluetooth adapters for all the wardriving and bluejacking anyone could ever want. [Corrosion] also included a 4 channel, 2.4GHz video scanner for warviewing. Everything runs off of a 12 inch netbook that will eventually run linux, and we’re really liking the 1970s suitcase aesthetic the WARS has – it looks like [Corrosion] is about to step into the set of a Beastie Boys video.

We were wondering about including a long range RFID sniffing antenna (PDF warning) behind the monitor of the suitcase’s monitor and asked [Corrosion] about it. He said it sounded doable, but is out of funds at the moment, so if you know how to build a cheap RFID antenna with a 50 foot range, drop [Corrosion] a line.

There’s a video demo with some stills of the build included after the break.

Long-range Bluetooth Wardriving Rig

April 15, 2011 by Mike Nathan 56 Comments

[Kyle] was digging through a box of junk he had lying around when he came across an old USB Bluetooth dongle. He stopped using it ages ago because he was unsatisfied with the limited range of Bluetooth communications.

He was going to toss it back into the box when an idea struck him – he had always been a fan of WiFi wardriving, why not try doing the same thing with Bluetooth? Obviously the range issue comes into play yet again, so he started searching around for ways to boost his Bluetooth receiver’s range.

He dismantled the dongle and found that the internal antenna was a simple metal strip. He didn’t think there would be any harm in trying to extend the antenna, so he soldered an alligator clip to the wire and connected the CB antenna in his truck. His laptop sprung to life instantly, picking up his phone located about 100 feet away in his house. He took the show on the road and was able to pick up 27 different phones set in discoverable mode while sitting in the parking lot of a fast food chain.

While it does work, we’re pretty sure that the CB antenna isn’t the most ideal extension of the Bluetooth radio. We would love to see what kind of range he would get with a properly tuned antenna.

Keep reading to see a quick demonstration of his improvised long-range Bluetooth antenna.

Hackaday Links: December 7 2009

Ah the beauty of watching molten solder pull SMD components into place. Yeah, we’ve seen it before, but for some reason it never gets old.

The glory days of wardriving are certainly behind us but if you’re still hunting in certain areas for access points you can leave the laptop at home. A homebrew program called Road Dog can turn your PSP into a WiFi search device. You must be able to run custom code to use this app.

Ferrofluid is our friend. But having grown up watching the Terminator and Hellraiser movies we can’t help being a little creeped out by the effects seen in this movie.

Follow along with the NASA astronauts in this 20 minute HD tour of the international space station. It’s a cramped place to live but we can’t help thinking that it looks incredibly clean. After all, where would the dirt come from?

How are your woodworking skills? Can you take a wooden block and turn it on a lathe until you have a lampshade 1/32″ thick? We’d love to see how these are made, but imagine the artist’s reaction when hours of labor are ruined by a minuscule amount of misplaced pressure on a carving tool. Patience, we’ll learn it some day!

This video from the past that is about the future of travel does leave us wondering why our cars don’t have built-in radar for poor visibility? We’ve already realized the rear-view-mirror-tv-picture, but we’re going to need your help before the flying police/fire/ambulance-mobile is a common sight. Oh, the fun of seeing a high-tech push-button selector 3:30 into the video. Perhaps the touch-screen was a bit beyond the vision of the time.

Sometimes you have so many servants you need to find creative things for them to do. Only the most discriminating of the super-rich employ a person whose sole responsibility is to erase and redraw the hands of a clock each minute. This video is obviously a result of the global recession as the live time-keeper has been let go; a looping recording took his job!

Last time we checked in with [Marco Tempest] he was syncing video over multiple iPhones. Now he’s at it again with an augmented reality setup. A camera picks up some IR LEDs in a canvas and translates that into information for a video projector. We’d call this a trick, but it’s certainly not magic.

Ekahau HeatMapper Maps Out WiFi Signals

The term ‘warwalking’ isn’t used very often, but the Ekahau HeatMapper adds a new tool to the pod bound hacker’s arsenal. The tool maps out wireless access points as well as their signal strength within a facility. A test of the HeatMapper on a map made with AutoDesk Dragonfly accurately determined the location of a router within 3 feet and helped tune the angle it needed to be at for maximum range. Ekahau made a fantastically cheesy promotional video for their product, which is viewable after the jump. The program is free of charge, but unfortunately only runs on windows, so mac and *nix users are out of luck, though it might run under wine.

Criminals Steal Credit Card Data Just By Wardriving

August 15, 2008 by Strom Carlson 24 Comments

A federal grand jury in Boston has charged eleven people with the theft of more than 41 million credit and debit card numbers from retail stores. What makes this case interesting is that, although the defendants stole the data from retail establishments, they did so without ever having to leave their cars; they stole the numbers while wardriving. While the report doesn’t make it clear whether the targeted networks used weak encryption or were simply unsecured, it’s obvious that the security of your data is still not a top priority for many companies.
