Introduction
Reverse engineering is a process where an engineered artifact (such as a car, a jet engine, or a software program) is deconstructed in a way that reveals its innermost details, such as its design and architecture. This is similar to scientific research that studies natural phenomena, with the difference that no one commonly refers to scientific research as reverse engineering, simply because no one knows for sure whether or not nature was ever engineered.
In the software world reverse engineering boils down to taking an existing program for which source-code or proper documentation is not available and attempting to recover details regarding its’ design and implementation. Binary reverse engineering techniques aim at extracting valuable information from programs for which source code in unavailable. In some cases it is possible to recover the actual source-code (or a similar high-level representation) from the program binaries, which greatly simplifies the task because reading code presented in a high-level language is far easier than reading low-level assembly language code. In other cases we end up with a fairly cryptic assembly language listing that describes the program. This book explains this process and why things work this way, while describing in detail how to decipher the program’s code in a variety of different environments.
