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.

Questions

  1. What is the GPIOC_ODR register that I XOR in the blinking example? Can you achieve the same effect by using other registers?
  2. Is it possible to have the MCU run at 72 MHz for the HSI? Why or how? What is to be expected then?
  3. What are the premade frequency assignment functions available in libopencm3?
  4. XOR each character of the string Z9kvzrj8 with 0x19 in a C program. What does this mean?
  5. What is the address of the GPIOC_ODR register? How can we find that easily?
