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.

Decrypting iOS applications

Since iOS apps are encrypted by Apple's FairPlay DRM, unencrypted versions are not available for download via third-party app stores. To view the contents of an iOS app, it must be first decrypted and extracted. Although encrypted IPA files can be downloaded directly from iTunes, it is a manual process to decrypt the app manually using tools like otool, lldb, and dd. Thankfully, this process has been automated using a tool known as Clutch2.


Dumpdecrypted is another tool that can be used to dump decrypted iOS applications to a file, but will not be used in this chapter. Dumpdecrypted can be found via the repository at

Getting ready

For this recipe, otool will be used, which is included with XCode's command-line tools. Installing XCode command-line tools can be accomplished by executing the following command in an OS X terminal:

$ xcode-select -install

Clutch2 will be used to decrypt applications. Clutch2 can be downloaded...
