The chip seen just above the center of this image is an ARM Cortex-M3. It provides the ability to interface and program the main chip on the STM32F3 Discovery board. The protocol used is the ST-Link/V2 which has become the standard for ST Microelectronics development boards. The thing is, that big ARM chip near the bottom of the image has multiple UARTs and bridging a couple of solder points will … [Read more...]

Signal sniffing some laundry pay cards

It seems that [Limpkin] was up to no good this weekend. He decided to snoop around inside a smart-card laundry machine. He posted about his larceny  adventure and shared the details about how card security works with this machine. We're shocked that the control hardware is not under lock and key. Two screws are all that secures the panel to which this PCB is mounted. We know that machines … [Read more...]

He brainstormed, trying to figure out the best way to recover his data. He considered … [Read more...]

Enhance your key fob via CAN bus hacking

can_bus_hacking

[Igor] drives a 4th generation Volkswagen Golf, and decided he wanted to play around with the CAN bus for a bit. Knowing that the comfort bus is the most accessible and the safest to toy with, he started poking around to see what he could see (Google translation). He pulled the trim off one of the rear doors and hooked into the comfort bus with an Arudino and a CAN interface module. He sniffed … [Read more...]

Wireless Sniffing and Jamming of Chronos and iclicker

Picture 1

The ubiquitous presence of wireless devices combined with easy access to powerful RF development platforms makes the everyday world around us a wireless hacker's playground. Yesterday [Travis Goodspeed] posted an article showing how goodfet.cc can be used to sniff wireless traffic and also to jam a given frequency. We've previously covered the work of [Travis] in pulling raw data from the IM-ME … [Read more...]
