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 which are the most common types of artifacts found on an iOS device and how to analyze these files.

First, we introduced databases and learned how SQLite organizes data into tables, columns, and rows. Then, we took a deep dive into SQLite's internal architecture to understand how records are organized at a lower level and where deleted records can be found. We discussed possible options to attempt the recovery of deleted data, such as manually analyzing the database through a hex viewer or using tools such as FQLite.

Further on in the chapter, we talked about property lists and protocol buffers, which can also be found on iOS devices in XML or binary format. To be readable, these files first need to be decoded.

Finally, in the last part of the chapter, we outlined some common locations where artifacts can be found and listed some essential files that should be considered in every investigation. In the next chapter, we will discuss...
