Practical Hardware Pentesting

By: Jean-Georges Valle

Overview of this book

If you’re looking for hands-on introduction to pentesting that delivers, then Practical Hardware Pentesting is for you. This book will help you plan attacks, hack your embedded devices, and secure the hardware infrastructure. Throughout the book, you will see how a specific device works, explore the functional and security aspects, and learn how a system senses and communicates with the outside world. You’ll set up a lab from scratch and then gradually work towards an advanced hardware lab—but you’ll still be able to follow along with a basic setup. As you progress, you’ll get to grips with the global architecture of an embedded system and sniff on-board traffic, learn how to identify and formalize threats to the embedded system, and understand its relationship with its ecosystem. You’ll discover how to analyze your hardware and locate its possible system vulnerabilities before going on to explore firmware dumping, analysis, and exploitation. The reverse engineering chapter will get you thinking from an attacker point of view; you’ll understand how devices are attacked, how they are compromised, and how you can harden a device against the most common hardware attack vectors. By the end of this book, you will be well-versed with security best practices and understand how they can be implemented to secure your hardware.

Finding back the data

GNU Radio is a set of software tools that allows you to create a signal processing chain for the data that comes from your SDR hardware (or a file) to either your hardware again (to emit) or a file. The blocks in its GUI (gnuradio-companion) are individual processing steps in the signal processing chain. Data comes from a source toward a sink (both are files or your SDR hardware driver, your sound card, or... well, it can be a lot of things: another program, a network endpoint, and so on).

Note

gnuradio-companion (grc) has two main GUI frameworks it can talk to: QT and WX. Depending on your installation, you may have to change the framework in the generate options block. The GUI-related processing blocks will also have to be changed in the processing flow itself.

So, let's fire up gnuradio-companion and make a receiver.

First, let's replicate Gqrx and let's have an FFT visualization. FFT is a visualization of the signal in the frequency...
