Binary Analysis Cookbook

By: Michael Born

Overview of this book

Binary analysis is the process of examining a binary program to determine information security actions. It is a complex, constantly evolving, and challenging topic that crosses over into several domains of information technology and security. This binary analysis book is designed to help you get started with the basics, before gradually advancing to challenging topics. Using a recipe-based approach, this book guides you through building a lab of virtual machines and installing tools to analyze binaries effectively. You'll begin by learning about the IA32 and ELF32 as well as IA64 and ELF64 specifications. The book will then guide you in developing a methodology and exploring a variety of tools for Linux binary analysis. As you advance, you'll learn how to analyze malicious 32-bit and 64-bit binaries and identify vulnerabilities. You'll even examine obfuscation and anti-analysis techniques, analyze polymorphed malicious binaries, and get a high-level overview of dynamic taint analysis and binary instrumentation concepts. By the end of the book, you'll have gained comprehensive insights into binary analysis concepts and have developed the foundational skills to confidently delve into the realm of binary analysis.

Confusing static analysis tools

There comes a time during analysis where you just might not be able to trust objdump. Confusing objdump isn't terribly difficult and just a few extra bytes can cause objdump to go nuts. Still, it's important that we learn to recognize instructions in the tool's output that just don't make sense as we're manually following along. After all, sometimes, our analysis is complicated by our tools instead of aided by them. So, it's important to see what that looks like from an analysis perspective.

In this recipe, we'll look at yet another alteration to the binary's original source code and see how that negatively impacts the output of objdump during static analysis and disassembly. We will perform a comparison between the output of the disassembled original binary versus the output of the altered binary.
