Mastering Mobile Forensics

By: Soufiane Tahiri

Overview of this book

Mobile forensics presents a real challenge to the forensic community due to the fast and unstoppable changes in technology. This book aims to provide the forensic community an in-depth insight into mobile forensic techniques when it comes to deal with recent smartphones operating systems Starting with a brief overview of forensic strategies and investigation procedures, you will understand the concepts of file carving, GPS analysis, and string analyzing. You will also see the difference between encryption, encoding, and hashing methods and get to grips with the fundamentals of reverse code engineering. Next, the book will walk you through the iOS, Android and Windows Phone architectures and filesystem, followed by showing you various forensic approaches and data gathering techniques. You will also explore advanced forensic techniques and find out how to deal with third-applications using case studies. The book will help you master data acquisition on Windows Phone 8. By the end of this book, you will be acquainted with best practices and the different models used in mobile forensics.

Decompiling and disassembling

Decompiling and disassembling are both kinds of a reverse engineering process that do the opposite of what a compiler and an assembler do.

A decompiler translates a compiled binary's low-level code designed to be computer readable into human-readable high-level code. The accuracy of decompilers depends on many factors like the amount of metadata present in the code being decompiled and the complexity of the code (not in terms of algorithms, but in terms of sophistication of the high-level code used). The bytecode format used by Java Virtual Machine (JVM) and the intermediate language used by .NET framework Common Language Runtime (CLR) include, in most cases, a very extensive amount of information and high level features. This makes the process of creating a high-level code from a compiled input quite feasible, and in most cases, very reliable. Most of the decompilation processes pass through seven steps before producing a readable high level code: loading...
