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.

Building a timeline with Magnet AXIOM

The Timeline Explorer within Magnet AXIOM gives the examiner a clear view of what's happening on a device at a certain point in time.

At the top of the view, an interactive graph visually displays time, allowing the examiner to identify spikes in device activity, focus on a specific time frame, and establish behavioral patterns. At the bottom of the screen, a table will list all the timestamped artifacts in chronological order.

The following screenshot shows what a timeline looks like:

Before a timeline can be viewed, the tool will need to complete an indexing process that, in turn, generates the timeline. If default options are enabled, Magnet AXIOM will not automatically build the timeline, so the examiner will need to manually start the process by following these steps:

  1. From the AXIOM Examine main menu, choose Tools | Build timeline.
