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.

Threat modeling firmware

In the previous recipe, we conducted a threat model of a DVR system and rated a threat case that would help with prioritizing vulnerabilities to test. In this recipe, we will go through threat modeling firmware for the same DVR system.

Getting ready

In this exercise, we will use the free online diagram software to help with demonstrating relationships in diagrams within firmware. This tool is a Chrome app and ties to third-party services for storage such as Google Drive or GitHub. We can draw relationships and processes that overlap, which is not possible in the Microsoft tool. Any tool that can effectively draw the architecture with their respective relationships of the target device or software will suffice.

To get started with drawing diagrams, perform the following steps:

  1. Select Create New Diagram.
  2. Select Software Design.
  3. Select the deployment diagram template as shown in the following screenshot:
  1. Remove all unused diagrams in the template and leave...
