Description

Building a Reflective DLL Loader in C++. This course provides an in-depth look at reflective DLL loading techniques in C++, with a focus on Windows internals, reverse engineering, and security analysis. This course provides an in-depth look at reflective loading techniques in C++ from the perspective of Windows internals, reverse engineering, and cybersecurity defense research. Participants will learn how to load and execute executable modules directly from memory without the need for a standard operating system loader, while gaining a deep understanding of the underlying mechanisms that enable these techniques. This course covers key concepts including the executable file format (PE Format), process memory structure, relocations, import resolution, memory protection, and related Windows APIs. Through guided demonstrations, code analysis, and hands-on lab exercises in an isolated environment, learners will explore how reflective loading implementations work and how these behaviors emerge during malware analysis and incident response processes. The training focuses equally on identifying signs of in-memory execution, understanding how modern security products detect these techniques, and applying defensive methods to inspect and hunt for threats. By the end of the course, participants will be able to describe reflective loading architecture, analyze implementations using debugging and reverse engineering tools, identify forensic traces associated with in-memory code, and enhance their ability to detect, analyze, and respond to complex threats while adhering to ethical, legal, and responsible security research practices. This course is highly applicable and useful for penetration testers, red team members, malware analysts, and cybersecurity researchers.
