[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.
[Jeffery] hacked the Bluetooth standard in order to use this bracelet as a custom display. He took up our challenge to hack the device when we first saw it back in February.
In order to display his own messaged he looked into how the HFP is implemented in the Bluetooth stack. The details are shared in his readme file but it goes something like this: The Bluez package needs to be compiled with a dummy backend that is not phone-specific and that will then allow external manipulation of the data being sent. This provides something of an API that a Python script can manipulate. His proof-of-concept allows for the script to be called with the message you want displayed as the command line argument. This should be simple enough to incorporate for just about any purpose that suits your fancy. Unfortunately, messing with the Bluetooth package in this way makes it impossible to use other devices with your phone, but that’s a hack for another day.
Today we received two very interesting hacks utilizing old cellphones within a matter of minutes of each other – Of course, this means war!
In the left corner we have the Mobile Mobile, a 50 cell phone collection dangling high above our heads by [James]. Loyal readers will remember his last match, a physical realization of the Spinning Wheel of Death. But today, Mobile Mobile tries to keep his title with the use of Twitter and live video.
In the right corner we have competition and newcomer [Timo] and his Cellphone Symphony. With a combined amount of 150 cell phones including sim cards, he is going to be one tough cookie. It’s all down to this folks.
Both utilize MIDI to try and lift spirits this holiday season by playing music and sounds. Servers and custom software are of course both necessities… but who will be the winner? Check out after the break!

Why take an iPhone, a slim device that already takes decent photographs and add several macro magnifying lenses? For [Mathijs], simply because he could, But now he can take some awesome macro pictures.
[Bhautik] (maker of the tilt-shift Plungercam) took the concept further. With some more trademark plumbing supplies and a lot of duct tape, secured an interchangeable SLR lense assembly to the back of his iPhone.
Check out some photos from both setups after the break. Continue reading “Double Dose Of IPhone Camera Hacks”

[Jesus Alvarez] sent us this funny little project. If you happen to have an iPhone and an old Apple Newton, you can use the iPhone as a keyboard for the Newton. You can download the schematic from his site to build the wire to connect the two. After that, you have to run an app on your iPhone that you can find once you’ve jailbroken your phone. At that point you are ready to go. Aside from the ability to say you could, we’re not sure why you would do this. It made us chuckle though. Maybe we’re not firing on all synapses though due to turkey overload.
The security door at the front of [Oliver’s] building uses an intercom system to let in guests remotely. Each unit has an intercom handset with a button that unlocks the door. [Oliver] wanted a way to enter without carrying any extra items so he built a system to unlock the door with his cell phone.
He patched into the intercom and attached a GSM module. The module runs python so he wrote a script that will monitor the entryway buzzer, then wait for an approved cell phone connection to unlock it. He went through a couple of different iterations for the final project. The first attempt used XBee modules to communicate between the intercom handset and the GSM module. For the final version, he snaked cable through his wall using rare-earth magnets (creative!) in order to forgo the use of a battery in the handset.
Who doesn’t carry a cell phone with them? Because of this, the use of GSM modules in automation is a trend we think will continue to gain popularity.
Nokia team PUSH is proud to announce they have winners from the contest they held over the past two months. You may remember when we first told you about the competition, but here’s a recap. All you had to do was think of a good hack for the Nokia N900! Winners will receive funding and other resources to make their hack come alive. What possible hacks made the cut?
Haptastic – A compass and map? Not any more with this wearable guide that can lead the way.
