Analyzing Packed Malware: Practical Reverse Engineering

Malware authors constantly find new ways to hide their malicious code, often using runtime packers to bypass security controls and static analysis. Understanding how to detect and unpack these obfuscated executables is a critical skill for any security analyst or reverse engineer. This text-only course guides you through the core concepts of malware unpacking and reverse engineering. You will transition from recognizing basic file structures to systematically analyzing and unpacking protected executables to inspect their true behavior. What you'll learn: Understand the fundamentals of runtime packing, obfuscation, and how malware evades detection; Identify packed executables using entropy analysis and Portable Executable (PE) header inspection; Perform static analysis on obfuscated files using tools like Ghidra and PEview; Execute dynamic analysis and debugging workflows using x64dbg to find the original entry point (OEP); Reconstruct unpacked executables and dump memory payloads for further threat intelligence; Apply modern security workflows to analyze real-world packing techniques. You will start by mastering foundational terminology and file structures before progressing to hands-on, step-by-step written walkthroughs of static and dynamic unpacking techniques. This course is designed for beginner cybersecurity enthusiasts, threat analysts, and aspiring reverse engineers. No prior malware analysis experience is required, though a basic familiarity with operating system concepts is helpful. Start reading today and build your malware analysis toolkit.
