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.

Exploiting MIPS

Now that we have basic information about how to reverse engineer binaries, it's time we get into a bit of depth on exploitation and understanding the architecture of the platforms on which IoT devices are mostly based. For getting a basic understanding, we will only focus on MIPS now, but it is highly recommended that you use the same concepts and perform exploitation on ARM-based architectures as well.

Getting ready

To perform MIPS exploitation, we would primarily do it using the QEMU and chroot technique which we glossed over earlier in this chapter. We will look into things such as how to perform buffer overflow exploitation on MIPS binaries and subvert the program execution flow to what we want it to be instead of what the binary is supposed to perform. We won't go into concepts such as Return Oriented Programming (ROP) for now and keep things simple.

How to do it...

For this exercise, we will require and use the following tools and utilities:

  • Damn Vulnerable Router Firmware...
