From Signal to Bits with SDR – Hands-on wireless reverse engineering

„Radio… The final IoT frontier…
These are the problems of hackers.
Our continuing mission:
To explore strange new signals…
To seek out new devices; new protocols…
To boldly detect what no one is aware of!“

In this session, an overview of typical problems during security assessments in the wireless world, state-of-the-art wireless signal identification and best practices for finding unknown signals will be provided. During the hands-on demonstration, the wireless reverse engineering process will be discussed and illustrated using a simple and easy to understand example. A practical example of how to reverse engineer a wireless power outlet control will demonstrate the process of getting bits and bytes out of unknown radio signals. The same methodology was used to perform security assessments of high risk wireless communication, such as pacemakers and implantable cardiac devices.
