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.

Understanding UART

UART (otherwise known as RS232 or serial) is a time-based protocol. The data travels on two wires.

From the MCU point of view, they are named as follows:

  • RX (Receive): The wire on which data comes from the peripheral
  • TX (Transmit): The wire on which data goes to the peripheral

The flow control can come in two main flavors:

  • With hardware flow control: Two additional control wires control the flow of the data. This hardware flow control itself can come in two flavors: either with control from the master, CTS (Clear To Send), or from the slave, DTR (Data Terminal Ready).
  • Without hardware flow control: UART without hardware flow control only takes care of "transporting the bits." There is no logic layer to it.

Error detection is also possible in the form of a parity bit added at the end of the transmission.

It can connect multiple devices but is not taking care of the addressing (the payload will have to take care...
