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 started with ARM and MIPS

Now that we know how to emulate firmware and perform basic analysis, you will often find yourself coming across various binaries which will require additional analysis. It is impossible for us to cover all the various architectures possible for an embedded device in a single book, we will focus on two popular architectures - ARM and MIPS.

We will, however, only look at exploitation of MIPS and look a bit into ARM reverse engineering. From an exploitation perspective, ARM and MIPS are quite similar and learning one architecture would give you a head start and basic understanding for the other.

Getting Ready

We will start our binary analysis journey with a very basic analysis of a backdoor found in D-Link firmware. This backdoor was found by Pierre Kim. To identify this backdoor, one would require a basic reverse engineering idea of ARM-based binaries. Even though we won't be going in-depth into registers and the architecture over here (since we are going to...
