IoT Penetration Testing Cookbook

By: Aaron Guzman, Aditya Gupta

Overview of this book

IoT is an upcoming trend in the IT industry today; there are a lot of IoT devices on the market, but there is a minimal understanding of how to safeguard them. If you are a security enthusiast or pentester, this book will help you understand how to exploit and secure IoT devices. This book follows a recipe-based approach, giving you practical experience in securing upcoming smart devices. It starts with practical recipes on how to analyze IoT device architectures and identify vulnerabilities. Then, it focuses on enhancing your pentesting skill set, teaching you how to exploit a vulnerable IoT device, along with identifying vulnerabilities in IoT device firmware. Next, this book teaches you how to secure embedded devices and exploit smart devices with hardware techniques. Moving forward, this book reveals advanced hardware pentesting techniques, along with software-defined, radio-based IoT pentesting with Zigbee and Z-Wave. Finally, this book also covers how to use new and unique pentesting techniques for different IoT devices, along with smart devices connected to the cloud. By the end of this book, you will have a fair understanding of how to use different pentesting techniques to exploit and secure various IoT devices.

Hands-on with SDR tools

In this section, we will look at the most common tools used for SDR and analysis of radio signals. We will begin by getting started with the very basic tools and then use that to extract more information from radio packets.

Getting ready

To perform SDR-based security research, the following tools will be required:

  • Hardware:
    • RTL-SDR
  • Software:
    • GQRX
    • GNU Radio companion

To install the tools, the following repositories have the best build instructions.


Instead of installing from apt-get, ensure that you build GNU Radio companion to get a better experience of working with SDR.


SDR security research is also dependent on the performance of your system. Make sure that you have enough RAM allocated to the virtual machine you are performing these tasks in. If possible, use an Ubuntu instance as host to get the best experience.

How to do it...

An RTL-SDR is one of the best devices to get started with in the world of SDR. It's originally a TV tuner dongle with the Realtek chipset...
