Wireless systems, and their radio signals, are everywhere: consumer, corporate, government, amateur - widely deployed and often vulnerable. With the exponential growth of connected devices in the IoT space there are more devices then ever using the airwaves.

This hands-on workshop will teach you how to find, analyse and begin to reverse engineer any signal. Focus will be on the 433 MHz band a which is non-regulated and commonly used in IoT.

Course outline:

  1. Introduction to software defined radio (SDR) and radio waves. This include some theory on radio waves, bands, modulation, etc
  2. Introduction to gnuradio
  3. Introduction to RTL-SDR
  4. Listening to radio waves with gnuradio - hands-on
  5. Capturing and reverse engineering radiowaves with gnuradio
  6. Introduction to universal radio hacker (urh)
  7. Capturing and reverse engineering radiowaves with urh
  8. Hands-on exercises with 433 Mhz using urh and arduino


If you have any SDR equipment, bring it along! I’ll bring some equipment with me. You will need a modern laptop with Linux or have the possibility to setup to run a VM with access to USB ports (8 GB RAM and ~50 GB on the HDD).

All the software tools needed are provided in a VM and I will bring 10 hardware kits for all the hands-on part. So it can have up to 20 people by making groups of 2. These kits will lent to the participants, and can be sold to those interested.
