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.

  1. Encryption: The goal of encryption is to make it impossible to read for someone who does not have the keys necessary to read the signal. The goal of encoding is to make it easy or possible to transmit and receive but it does secure the information.
  2. The fast Fourier transform is used to transform a signal in a time domain (what did I receive and when?) to the frequency domain (what kind of frequencies is my signal made out of?).
  3. The modulation scheme indicates what change(s) in physical dimension(s) (change in frequency, amplitude, phase, or a combination) of the signal is used to encode the information.
  4. Sampling frequency and available frequency range.
  5. Imagine a signal as a sinusoidal of wavelength x. If our dipole antenna is measuring x, the difference between one end and the other is 0! Our receiver would have nothing to measure!
