The SySS Radio Hack Box is a proof-of-concept software tool to demonstrate the replay and keystroke injection vulnerabilities of the wireless keyboard Cherry B.Unlimited AES.

• Raspberry Pi
• Raspberry Pi Radio Hack Box shield (a LCD, some LEDs, and some buttons)
• nRF24LU1+ USB radio dongle with flashed nrf-research-firmware by the Bastille Threat Research Team, e. g.
  • Bitcraze CrazyRadio PA USB dongle
  • Logitech Unifying dongle (model C-U0007, Nordic Semiconductor based)
• Python2
• PyUSB

For automatically starting the Radio Hack Box process on the Raspberry Pi after a reboot, either use the provided init.d script or the following crontab entry:

@reboot python2 /home/pi/radiohackbox/radiohackbox.py &

The Radio Hack Box currently has four simple push buttons for

• start/stop recording
• start playback (replay attack)
• start attack (keystroke injection attack)
• start scanning

A graceful shutdown of the Radio Hack Box without corrupting the file system can be performed by pressing the SCAN button directly followed by the RECORD button.

A demo video illustrating replay and keystroke injection attacks against an AES encrypted wireless keyboard using the SySS Radio Hack Box a.k.a. Cherry Picker is available on YouTube: SySS Cherry Picker

The hand-crafted Pi shield simply consists of an LCD, some LEDs, some buttons, resistors, and wires soldered to a perfboard.
