In this lecture we will peek into EPROCESS and ETHREAD structures in Windows kernel OS. We will understand PEB,TEB structures in user mode in Windows OS. We will see how PEB and TEB is related to each other in Windows OS.
This module explains the architectural linkage between the TEB and PEB structures in Windows.
You will examine how each thread maintains its own TEB, which includes a direct pointer to the process-wide PEB. This design enables efficient access to shared process metadata such as the loader data, module lists, and runtime parameters.
We will also discuss how this relationship is leveraged in advanced techniques like manual API resolution, PEB traversal, and evasion strategies in malware.
Understanding Windows Internals is one of the most important skills for anyone entering malware development, malware analysis, reverse engineering, or ethical hacking. This course is designed to give you a deep, practical understanding of how Windows really works behind the scenes, so you can build, analyze, and detect modern malware with confidence.
You will learn core Windows components such as processes, threads, memory management, system calls, handles, kernel objects, tokens, integrity levels, PE file loading, and the Windows security model. Each topic is explained in a simple, beginner-friendly manner with practical demonstrations, code examples, and real-world scenarios relevant to malware development and analysis.
Whether you want to write advanced malware, analyze malicious executables, bypass security controls, detect malicious behavior, or understand how red-team and threat actors operate, this course gives you the strong internal foundations required.
By the end, you will understand how malware interacts with Windows, how the OS reacts internally, and how to use this knowledge to develop more effective malware or to analyze and defend against sophisticated threats. This course prepares you for real-world malware development, BLUE team analysis, incident response, reverse engineering, and ethical hacking. It also strengthens your overall security mindset through deeper operating system awareness and practical understanding.
