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.

Identifying buses and interfaces

Now that we have a good understanding of the different components present in an embedded device, let's have a look at how we can identify the different buses and interfaces present in a device.

For this, the first step would be to open up the device and look at the PCB. Note that in this section, we will only be concerned with identifying what a particular pin, or header, or chip is for, rather than actually connecting to it, which is what we will cover in the next section.

How to do it...We will start by looking for UART which is one of the hacker's favorite interface to get access to the device. We will start by looking at the internals of UART, moving to how to identify the pinouts and finally how to connect with the target device.

UART identification

The first thing that we will look for in an embedded device is the universal asynchronous receiver transmitter (UART) interface. UART is one of the most common communication protocols found in embedded devices...
