About the Book

This is a complete, technically accurate guide to the latest version of IDA Pro (9.0 through 9.4 beta). It covers every major feature, workflow, and capability that a reverse engineer needs: installation and licensing, interface navigation, disassembly, decompilation, debugging, IDAPython scripting, IDC, plugin development, automation, proprietary APIs, reverse engineering methodologies, malware analysis, binary patching, collaborative workflows, performance optimization, and real-world case studies. It is written for junior reverse engineers who know the basics but want mastery, security researchers, malware analysts, exploit developers, and software engineers doing binary analysis.
