Start The Car With A Wave Of Your Hand

January 14, 2010 by Mike Szczys 74 Comments

[Jair2K4] likes his RFID almost as much as he likes his chaw. Ever since his car was stolen he’s had to start it using a screwdriver. Obviously this is not a good way to leave things so he decided to convert his starter to read an RFID tag. He installed an RFID transponder he picked up on eBay, wiring it to the ignition switch. He’s removed the clutch-check sensor and wired a rocker switch to enable the RFID reader. We presume the rocker switch will eventually be used to shut the car off as well.

While most would have purchased a key-chain RFID tag, [Jair2k4] went far beyond that and had the tag implanted in his hand. This is an honor usually reserved for pets and until he adds RFID functionality to the door locks maybe a key fob would have been a better answer. But, to each his own. See his short demonstration video after the break.

Kodak Digital Frame Vulnerability

January 11, 2010 by Mike Szczys 17 Comments

Kodak managed to release a product with a big fat security vulnerability. [Casey] figured out that the Kodak W820 WiFi capable digital frame can be hijacked for dubious purposes. The frame can add Internet content as widgets; things like Facebook status, tweets, and pictures. The problem is that the widgets are based on a feed from a website that was publicly accessible. The only difference in the different feed addresses is the last two characters of the frame’s MAC address. Feeds that are already setup can be viewed, but by brute-forcing the RSS link an attacker can take control of the feeds that haven’t been set up yet and preload them with photos you might not want to see when you boot up your factory-fresh frame.

It seems the hole has been closed now, but that doesn’t diminish the delight we get from reading about this foible. There’s a pretty interesting discussion going on in the thread running at Slashdot.

Spy On Your Office

January 7, 2010 by Jakob Griffith 30 Comments

[Garagedeveloper] sent us his custom surveillance system, part 1, part 2, and part 3 after needing a way to find out why some cables at work were becoming unplugged (spoiler, the cleaners were messing up the wiring). At the base of the system is a web cam glued to a stepper motor. However, it gets much more in depth with a web front-end that allows the user to stream the feed and control the position of the stepper. We’re not particularly fond of how many different parts the project takes, while it all could be accomplished under C# with ASP.NET and parallel port library instead of including Arduino and excess code, but to each their own and the project turned out a success anyway.

Arduino Security With Frickin’ Laser

January 3, 2010 by Mike Szczys 15 Comments

[over9k] used his Arduino to set up a laser trip wire. The laser is mounted along side the Arduino, reflects off of a mirror, and shines on a photoresistor that interfaces via a voltage divider. The signal from the voltage divider is monitored for a change when the laser beam is broken. [over9k] set things up so that a webcam snaps a picture of the intruder and Twitters the event for easy notification. Video after the break walks through each of these steps.

This build is a bit rough around the edges but unlike other laser trip wires this keeps all the electronics in one place. The laser interface could be a bit more eloquent, and we’re wondering just how much current it is pulling off of the Arduino pins. But if you’re bored and have this stuff on hand it will be fun to play around with it. Continue reading “Arduino Security With Frickin’ Laser” →

Lightning Rod: Keeps You Safe From Dirty Flashers

January 1, 2010 by Mike Szczys 9 Comments

A new open source package called Lightning Rod will help to close security exploits in Adobe’s dirty Flash code. A presentation made at the 26th Chaos Communication Congress showed that the package does its job by reviewing incoming code before the browser executes it. Heise Online is reporting that this method can block over 20 different known attacks and can even be used to filter out malicious JPG attacks. As more vulnerabilities are discovered they can be added to Lightning Rod to close the breach. This amounts to a virus scanner for Flash code. It’s great to have this type of protection but why can’t Adobe handle its security problems?

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.

Kindle DRM Cracked

December 24, 2009 by Mike Szczys 19 Comments

Ding-dong, the DRM is gone. But not in the way we really want. The copy protection scheme that is used for most Kindle books has been cracked. We’d much prefer it hadn’t been there in the first place but then there’d be no challenge for security hackers.

Giving credit for the advancement gets a little messy. Apparently two folks figured this out at approximately the same time. [Labba] posted about his discoveries while [I (heart) Cabbages] wrote about his exploits in a blog entry. Either way, you can now strip the protection and use your legally-purchased books on any device you choose by using this Python script.

This means that both Kindle and Nook have had their DRM broken. Are these companies really trying to prevent copying (fair use) or do they just want to be able to tell the publishers that there are copy protections while turning a blind eye to what happens in the privacy of your personal computer?
