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.

Uncommon screw types

The first step for a hardware attacker is to open up the device to look at the chips on the PCB and various exposed interfaces. This can be protected to an extent using uncommon screws, which are tough to open or by using things such as ultrasonic welding or high-temperature glue to seal the multiple hardware enclosures together.

Some of the common screw types are shown in the following figure:


If you decide to have unique/less common device screws, it would make it tougher for attackers to open up your device, and the only option in most cases would be to break it open. Force opening, and even normal opening, can be resisted by adding components, which sense and detect the opening of a device, which is discussed in the next section.
