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.

Locating location artifacts

In the first part of this chapter, we introduced the Location Services API and learned how iOS uses different technologies to assess its position. Now, we'll take an in-depth look at the SQLite databases where geolocation data is stored.

The following is a list of files of interest that can only be found in a full filesystem extraction:

  • /private/var/mobile/Library/Caches/com.apple.routined/Cache.sqlite

This is the primary storage means for iOS location data. The ZRTCLLOCATIONMO table contains several useful records, such as GPS coordinates, timestamps, and a horizontal accuracy value, which is an indicator of how accurate the device believes the GPS coordinates to be. The ZRTWIFIACCESSPOINTMO table stores a list of Wi-Fi networks that the device has scanned. Generally speaking, data contained in this database should be considered up to date and accurate.
