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.

Preface

A fast CPU and a faster video card


The urge to have a fast CPU is self-explanatory, but why do we need a fast graphics card? And why do we state that having a fast video card is way more important than having a fast CPU?

The reason for that is GPU acceleration. Today's video cards are extremely fast. Just consider how much computational power is needed to support modern 3D games in high resolutions and 60 frames-per-second, and you'll realize it takes a lot of processing power.

Using that power to break passwords can give a significant boost to the speed of recovery. By offloading computation-intensive parts of the process to the massively parallel array of graphical processing units (GPUs) of a typical gaming board costing no more than $200-300, one can increase the speed of recovering iTunes passwords 10 to 20 fold. By using an even faster video card, or by utilizing two or more cards, one can boost speeds 30 to 50 fold compared to using a high-end quad-core CPU. Interestingly, ElcomSoft...
