Mobile Forensics ??? Advanced Investigative Strategies

By: Oleg Afonin, Vladimir Katalov

Overview of this book

Investigating digital media is impossible without forensic tools. Dealing with complex forensic problems requires the use of dedicated tools, and even more importantly, the right strategies. In this book, you’ll learn strategies and methods to deal with information stored on smartphones and tablets and see how to put the right tools to work. We begin by helping you understand the concept of mobile devices as a source of valuable evidence. Throughout this book, you will explore strategies and "plays" and decide when to use each technique. We cover important techniques such as seizing techniques to shield the device, and acquisition techniques including physical acquisition (via a USB connection), logical acquisition via data backups, over-the-air acquisition. We also explore cloud analysis, evidence discovery and data analysis, tools for mobile forensics, and tools to help you discover and analyze evidence. By the end of the book, you will have a better understanding of the tools and methods used to deal with the challenges of acquiring, preserving, and extracting evidence stored on smartphones, tablets, and the cloud.

Windows Phone physical acquisition


Apparently, Microsoft did a great job protecting Windows Phone devices. Indeed, Microsoft has full control over the platform (Qualcomm) that is used by the different manufacturers of Windows Phone devices, so unlike Android there can be no sub-standard implementations here. As a result, all Windows Phone devices are roughly equivalent in terms of security. Until very recently, JTAG and chipoff acquisitions were the only methods to acquire most Windows Phones. However, in January 2015, Cellebrite implemented an acquisition module enabling investigators to perform physical acquisition of a lot of Lumia devices. The technology is still at an early stage. There's still a lot to do in parsing the contents. However, the filesystem is NTFS, and the OS is very similar to Windows, so eventually, this will be done.

Since then, yet another development emerged. Windows Phone Internals (http://www.wpinternals.net/) developed a bootloader unlock method for Lumia 520,...
