Participants will learn how to reverse engineer the wireless communication between Internet Of Things devices with Software Defined Radios (SDR) using the Universal Radio Hacker (URH). The workshop covers required HF basics such as digital modulations and encodings and shows how to reveal the protocol logic step by step and, finally, develop attacks against devices. For demonstration we will investigate and attack a wireless socket and a smart home door lock.
During the course of the workshop the communication of the two devices will be analyzed and reverse engineered. In conclusion, attacks on both devices will be developed.
By the end of the workshop we'll be able to switch the socket and open the door lock with SDRs.
This of course requires knowledge in the field of modulation, coding and Log formats, which will be pracitcally conveyed during the workshop. "Learning by doing" is the motto.
For this to work, the participants need their own computer to operate the software (Universal Radio Hacker) which we use to analyze the signals and bring them back in.
If attendees already own a software defined radio (f.ex.HackRF), they can record the signals and attack the devices themselves. If that's not the case, I can make the signals available online so participants can download and import them into the Universal Radio Hacker.
In short:
What do I need?
Must have: laptop / calculator
Nice to have: Software Defined Radio (f.ex. HackRF)
What awaits me?
- Picking up of raw signals with Software Defined Radios
- Demodulation of raw signals to get Bits
- Decoding of the Bits
- Reverse engineering of the protocol format (where are addresses,sequence numbers etc.)
- Developing of attacks with fuzzing and simulation
We will elaborate this on the basis of two practical examples.
