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.

Understanding and exploiting BLE

BLE or Bluetooth Low Energy is one of the most common platforms found in a number of smart devices ranging from smart homes to medical device utilities to even fitness trackers and wearables. One of the reasons for the growing popularity of BLE is that pretty much all smartphones that we use today support BLE, thus making it easier to interact with BLE-based IoT devices.

BLE is designed for devices with resource and power constraints which BLE effectively solves by providing short bursts of long range radio connections, thus significantly saving battery consumption.

BLE was initially introduced in Bluetooth 4.0 specifications focusing on the devices which needed a mode of communication with extreme low power consumption, where BLE claimed to last from a couple months to several years on a single coin cell battery.

A BLE device can operate in four different modes based on its current connection and operational phase:

  • Central device and peripheral device: In this...
