Overview of this book

Professionals working in the mobile forensics industry will be able to put their knowledge to work with this practical guide to learning how to extract and analyze all available data from an iOS device. This book is a comprehensive, how-to guide that leads investigators through the process of collecting mobile devices and preserving, extracting, and analyzing data, as well as building a report. Complete with step-by-step explanations of essential concepts, practical examples, and self-assessment questions, this book starts by covering the fundamentals of mobile forensics and how to overcome challenges in extracting data from iOS devices. Once you've walked through the basics of iOS, you’ll learn how to use commercial tools to extract and process data and manually search for artifacts stored in database files. Next, you'll find out the correct workflows for handling iOS devices and understand how to extract valuable information to track device usage. You’ll also get to grips with analyzing key artifacts, such as browser history, the pattern of life data, location data, and social network forensics. By the end of this book, you'll be able to establish a proper workflow for handling iOS devices, extracting all available data, and analyzing it to gather precious insights that can be reported as prosecutable evidence.

Summary

In this chapter, we learned what the goal of a forensic examination is and how the discovery of the checkm8 vulnerability provides new opportunities for data acquisition from iOS devices.

First, we introduced the iOS operating system and discussed some key elements of its security architecture, such as Secure Enclave and Data Protection. Then, we went through the steps of an iOS forensic examination.

The first step is seizing the device and adopting techniques to preserve evidence, such as placing the device in a Faraday bag or enabling Airplane mode. There are different ways to acquire data from an iOS device, depending on the model, iOS version, and what tools are available. This chapter covered logical and filesystem acquisition techniques, as well as jailbreaking and agent-based extractions.

Analyzing artifacts should be done by following a thorough validation process that ensures that commercial tools produce consistent results and that evidence has been processed in a forensically sound way.

Finally, we learned what key elements should be included in a forensic report.

The next chapter will discuss iOS data acquisition in detail and provide a hands-on approach to the tools that are used to conduct a forensic examination.
