Luis Miras presented “Other Wireless: New ways of being Pwned”. Instead of common con topics like Bluetooth or WiFi, this dealt with the cheap radios used in wireless keyboards, mice, and things like the wireless remote pictured above. These RX/TX pairs are found in 27MHz, 900MHz, and 2.4GHz versions. The devices all use the same main components: a microcontroller, an EEPROM for storing the serial number, and the transmitter. The dongle is nearly the same only with a receiver.

Wireless Card = ARM Development Platform
[Archantos] sent us this one. The mustumbler project is actually trying to use some external hardware to make a miniature wireless stumbler. [Archantos] points out that it’s could be a cheap way to get your hands on an ARM development platform. He’s right. Just a few connections gets access to the I2C bus, a GPIO expander for I2C runs the LCD and an EEPROM is there for program storage. The software is still being sorted out, but the hardware itself is functional. If they can manage to reverse engineer the Conexant chipset, they should have a very promising platform.
