Unlocking Wireless PC Locks

July 27, 2011 by Kevin Dady 17 Comments

[Mr.Pantz] pointed us to a web page we thought you would find interesting. It deals with hacking PC lock using a Universal Software Radio Peripheral (USRP) . Following the good practice of logging off or locking your workstation while your not at it, it is darn hard to get users to actually do it. These little gadgets are a 2 piece setup one being a usb dongle, and the other being a badge like device. If the badge is turned off or is a distance greater than ~30 feet, the signal is lost and the pc is locked.

From there all you really need to do is figure out what frequency the 2 are running at and what codes are flying around the air. Some careful eyeballing suggests that this operates in the 434MHz region much like remote lock dongles for your car, and once the device is apart some research of 2 of the IC’s on board confirms it. Using the GNU Radio spectrum analyzer a signal is quickly captured, dumped, and a script is created to send the signal back out, provided you have the correct hardware to do so.

The Isostick

The Isostick, a Kickstarter project now in development, is meant to emulate an optical drive in the form of a USB stick. Although there is nothing new with putting an iso file (optical disk image) on a USB stick, what is unique about this drive is that it fully emulates a drive without actually having to worry about drivers or extra programs.

When plugged in, a computer sees a flash drive and a virtual optical drive. An excellent feature is that this disk can store multiple “iso” files and select them with a built in utility program. This could be invaluable for a technician or hacker since more than one CD or DVD is often needed to complete a task.

If fully developed, one could expect to attach this “drive” to your keychain and not have to worry about lugging an optical disk around anymore. Also, the activity light is programmable, which is a nice bonus.

Driving Game Steering Wheel Controller Without The Wheel

July 6, 2011 by Mike Szczys 18 Comments

For some reason this project makes us think of the Light Cycles in Tron. You know, the bike forms around the rider after they grab onto the wand that makes up its controls? Certainly you’re not going to see a car form out of thin air, but this driving controller let you grab onto nothing to control a racing game.

You can see that it uses a Kinect to map the body of the player and convert your movements into motion control. The demo video embedded below the fold shows the calibration step, followed by the available control options. Pushing the steering wheel forward turns on the nitrous, leaning forward or back accelerates and brakes, and a few arm signals let you navigate the game menus.

This works by mapping gestures to keystrokes. [Rajarshi Roy] tells us that there’s a very raw code package available in their repository but the plan is to clean it up this weekend. They will also work on a Wiki, documentation, and a tutorial on teaching the software new gestures.

We just don’t know what we like better, seeing the kinect extended as a gaming controller like this one, or using it in robotics like that quadcopter.

Teensy AVRs Used In Penetration Testing

While some people know that you should be wary of USB drives with unknown origins, the same care is rarely, if ever exercised with USB peripherals. The security firm Netragard recently used this to their advantage when performing a penetration test at a client’s facility. When the client ruled out the use of many common attack vectors including social networks, telephones, social engineering, and unauthorized physical access from the test, the team at Netragard knew they would have to get creative.

They purchased a Logitech USB mouse and disassembled it in order to add their clever payload. A Teensy uC was programmed to emulate keyboard input, entering commands via the mouse’s USB connection once it had been connected to a computer. Using an undocumented exploit in McAfee’s antivirus suite, they were able to evade detection while their system entered commands to install malware from the flash drive they hid along side the Teensy.

Once the mouse was reassembled, they repackaged it along with some marketing materials to make it look like part of a promotional event. They purchased a detailed list of employees and singled out an easy target, sending their malicious mouse on its way. Within three days, their malware was loaded onto the victim’s computer and their test was deemed a success.

Receipt Racer Wastes A Lot Of Paper

June 20, 2011 by Brian Benchoff 40 Comments

[Joshua Nobel] and the team at undef came up with a receipt printer game for the OFFF 2011 festival in Barcelona.

The game is a small openFrameworks app that prints a maze on a thermal printer. A ‘car’ is guided through the maze with input taken from a DualShock 3 controller. The game is limited to a maximum distance of 50 meters, the length of the roll of paper. We wondered about the waste of paper this would be until undef pointed out, “ecologically it’s pretty much a disaster, just like any real car.”

The undef team tried to use the printer for the entire visual representation of the game but that didn’t quite work out until [Joshua Noble] came up with a ‘beamer’ to project the car and score onto the paper. We’re not quite sure what the ‘beamer’ is, but everything syncs up and the resulting game is quite nice.

The game itself reminds us of a certain flash game, but that can’t be where the original idea came from. Check out the Receipt Racer gameplay video after the break.

Mouse And HDD Combo Show Off Your Data Gluttony

June 16, 2011 by Mike Nathan 24 Comments

So we know you’ve got a lot of porn on your computer, but just how much is a lot? This concept mouse and hard drive combo aims to show you just how much digital junk you have acquired through physical feedback.

The DataBot mouse looks like a typical run of the mill scroll mouse that you might get with a new computer. Inside however, the designers have added a small servo which alters the ease with which the ball moves. The more files you have stuffed into the folder you are moving around, the more the mouse resists, giving you a sense of the physical “weight” of your computer’s contents.

The DataBot hard drive gives you a sense of how full your computer is by growing and shrinking based on space usage. During file transmissions the hard drive blinks its LEDs to indicate how fast or slowly your files are moving. When the inevitable file access error occurs, the LEDs switch to a bright red hue and the drive shakes to indicate there is a problem afoot.

With the price of data storage decreasing by the day, it’s easy to get lost in a glut of information without realizing just how much data you have. This is definitely an interesting way to get a different look at your data consumption.

Check out the videos below to see the pair in action.

We’ve Got A Real Bone To Pick With This Mouse

June 16, 2011 by Mike Szczys 19 Comments

Finally, there’s a way you can feel like a real bad-ass while you’re formatting those TPS reports. It’s all thanks to this computer mouse built inside the skull of a dog. [Shannon Larratt] dug through his collection of skulls and came up with this one because it fits nicely in the palm of your hand.

Before you get too grossed out, this is not actually part of an animal’s body like another notable mouse hack that comes to mind. [Shannon] started with the skull of a small dog, making a mold for the pieces used in the finished version above. He was quite creative when fitting the electronic parts inside of his reproduction. He pulled the PCB from a $10 Logitech mouse and had no trouble getting it to fit into the base of the skull. But when it came to the buttons he ended up engineering a couple of rockers and used a belt to reposition the scroll-wheel. Not wanting to lose the middle-click feature there’s an additional lever for that functionality. We’d also like to compliment him on the quality of his write-up. Fantastic!
