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.

Emulating firmware for dynamic analysis

Often, while working with IoT devices, one of the limitations is we are not able to perform a lot of tests and exploitation without having access to the actual device. However, in this section, we will discuss a way in which you can emulate your firmware and interact with the emulated device as if it were an actual device sitting on your network.

Getting ready

In order to emulate firmware, we will be using a script called Firmware Analysis Toolkit (FAT) written by the authors of this book. FAT uses Firmadyne in order to perform the emulation of firmware images.

The underlying utility used in Firmadyne is QEMU, which allows users to emulate the entire system architecture and run content on top of it. It also takes advantage of additional scripts written by the tool authors, such as the NVRAM emulator located at It also uses tools such as Binwalk, which we discussed earlier, to extract a filesystem from firmware which...
