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.

Getting familiar with SDR

SDR is an extremely useful technique with which we can vary the purpose of a given radio device. As the name suggests, the radio in this case is software defined, which means that the functionality, or the action that the radio performs, can be changed and modified based on our requirements. This is unlike traditional radios, where a particular device served a single purpose based on the hardware design present in it.

This opens up a plethora of opportunities for us, as we can get started with SDR and keep repurposing it to suit our various needs. Repurposing here simply means that let's say we are analyzing the FM spectrum, we can have the device do it, and, if later on we want to analyze the data coming out from an IoT device at 433 MHz, we can use the same device to capture the data, process it, and extract the text being sent in it.

By now you should have a decent understanding of what SDRs are and what purpose they can serve. Before going into the actual hands...
