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.

Introducing Bluetooth forensics

Using Bluetooth technology, users can transfer data between different devices and attach headphones, speakers, or any kind of wireless device to their smartphone. Typically, iOS devices operate as Class 2 Bluetooth devices, which means they can operate at a range of approximately 10 meters (33 feet).

From a forensic viewpoint, iOS devices maintain the following:

  • A list of low-energy Bluetooth devices that can connect to the user's device, also called paired devices. These are stored in the /private/var/containers/Shared/SystemGroup/<GUID>/Library/Database/com.apple.MobileBluetooth.ledevices.paired.db database, under the PairedDevices table. This table maintains a list of devices, their names, their Media Access Control (MAC) addresses, and their last-seen timestamps.
  • Other Bluetooth paired devices (not just low-energy), which are stored in the /private/var/containers/Shared/SystemGroup/<GUID>/Library/Preferences/com.apple...
