UAV Reigns Down Vengeance Upon Thee

December 30, 2009 by Mike Szczys 55 Comments

An unemployed electrical engineer can be a very dangerous thing. [Cybrown] has turned his skills toward darker, more awesome applications by building an armed unmanned aerial vehicle. This is a remote control airplane that has a movable camera mounted in the cockpit. Video and GPS data are sent back to the pilot who views the picture via a wearable display. We’re betting this doesn’t have the range that the 100km UAV did, but that’s good because this one brings doom from the skies. Check the wings in the picture above, this RC is fireworks-enable. We’ve embedded flight footage and attack video after the break.

Update: Here is a forum post covering this nugget of awesome. There are just a few details but the entire thread is interesting. Someone pointed this out in the comments but they don’t get credit because they didn’t leave a link.

GSM Cracked

December 30, 2009 by Devlin Thyne 14 Comments

[Karsten Nohl], with a group of security researchers has broken the A5/1 Stream Cipher behind GSM. Their project web site discusses their work and provides slides(pdf) presented at 26C3. A5/1 has had known vulnerabilities for some time now and is scheduled to be phased out for the newer KASUMI or A5/3 block cipher. This should be an interesting time in the cell phone business.

Thanks to [Tyco] and [MashupMark] for pointing us to this story.

Terminate RFID Tags

December 22, 2009 by Mike Szczys 49 Comments

This gun hunts only RFID tags.[mnt], who brought us laser gesture control, built this RFID Zapper but included so much more. Any good weapon has to sound mean, a feat he’s accomplished by incorporating an MP3 player into the rifle. The coil that zaps the RFID tag is powered by a photo-flash unit, but for visual feedback he’s got a second unit that flashes light to signal the demise of your German passport (see the video after the break).

It’s hard to believe we haven’t covered RFID Zappers yet. The concept came out of the Chaos Communication Congress a few years back. This method works by sending a very strong electromagnetic field through the RFID tag that causes it to burn out. There’s a wiki post on RFID Zappers but Firefox threw a certificate warning when we loaded it up; read at your own risk.

BobLight Night Light Networking

December 22, 2009 by Jake W 10 Comments

It turns out that more than just pictures of women and flashing animations can be found on the X10 website. [Jonathan] based his BobLight project around the MS14A X10 module.

The idea for the devices started off as a Christmas gift for his parents in-law. A boblight turns on when motion is detected. It then communicates (through radio) with the other boblights to turn them all on. If motion is not detected by any of the boblights for a length of time, they all turn off. Rather than having the user shut all of them off every morning, a light sensor is used to automate the task.

Each boblight is a common LED utility light combined with the board of an MS14A and added a 310MHz RF receiver. He even hacked the board by replacing the onboard PIC with a higher spec model. We think [Jonathan] did a great job at implementing an innovative concept.

Cheap Toy Yields Good Parts

December 19, 2009 by Mike Szczys 25 Comments

We’ve spent some serious time building robot chassis and motor controllers. [Whamodyne] does the smart thing and scavenges what he needs form cheap sources. He picked up an RC car from the local pharmacy for just $10, tore the body off and behold, a bounty of robot-friendly parts.

We’re not talking precision parts here, but we don’t scoff at two geared motors, four wheels, a driver board, and steering. There’s no great way to attach your own stuff but that’s half the fun of hacking. [Whamodyne] used the 9v battery that came with the toy to power his boarduino and quickly patched in to produce a miracle of automated locomotion.

Static Bleeder

December 17, 2009 by Caleb Kraft 31 Comments

When you are in the middle of the desert, pretty much every solution to a mechanical or electrical problem is a hack. [Sgt.M] who was deployed in Iraq sought out the help of radio guru [H.P. Friedrichs] about a static problem he was having. When dust storms would blow in strange things would happen in camp. Humming and crackling could be heard and [Sgt. M] actually had an electrical arc from a lamp to his hand at a distance of about 2 feet.

[Friedrichs] helped him find the problem. Their antennae were acting as static electricity collectors in the dust. All that dust friction in the dry air constantly built up a charge. The solution was simple, discharge the electricity at the antenna when it isn’t in use. Several solutions are outlined on the page, so check them out.

Pink Wireless-terminal Of Wonder

November 30, 2009 by Mike Szczys 53 Comments

[Hunter Davis] is at it again, this time hacking the pink IM-ME to use as a wireless terminal. It sells for between $12-16 and he ordered it to get free shipping with another purchase. The wireless antenna registered as an HID device when he plugged it into his Linux box. He then sat down for a long USB sniffing session only to be surprised by the lack of any type of security. Everything transferred to the device is just plain text in hexidecimal. Because of possible DMCA issues he hasn’t posted a driver but does explain most of the process to write your own.

[Hunter] has given us a lot of handheld hacks. This device is meant as a remote terminal for instant messaging. We’re sure you can think up a lot better uses so let us know in the comments and don’t forget to send in any projects you come up with.

[Thanks Paul]
