Below The Binary: A Practical Guide to Reverse Engineering

The technical guide to binary analysis for security professionals who want to understand what a program does when no one explains it.Behind every executable there is a story - a set of design decisions, implementation mistakes, obfuscation layers, and protection mechanisms that only become visible when you know where to look. Under the Binary teaches you to read that story.Written for practitioners with a solid technical foundation, this book builds a complete and progressive path through binary analysis - from processor architecture to modern malware evasion - with no shortcuts and no hand-waving.What you will find inside: - x86 and x86-64 assembly from fundamentals to applied intermediate level- Static and dynamic analysis of PE and ELF executables- Windows and Linux internals: what malware manipulates and what reversers need to know- Anti-reversing techniques and how to neutralize them- Reversing .NET, Java, Android, and iOS applications- Applied cryptography: identifying algorithms in binaries without source code- Complete practical case studies, ordered from lower to higher difficultyThis is not a scripting book or a tool guide. It is the book you need to understand what a binary does - and why.
