Chapter 1: Introduction#

Welcome to the world of malware reverse engineering! If you’re here, you likely already have a strong interest in understanding how malicious programs work and how to analyze them. In this course, we will explore the fundamentals of malware reverse engineering, including techniques to identify, analyze, and respond to threats. We’ll learn common tools and strategies used by security professionals to detect and defeat the latest malicious code. Get ready to expand your knowledge and take your security skills to the next level!

Chapter 2: File Analysis#

File analysis is an important step in malware reverse engineering. It involves the examination of a malicious executable file to determine the purpose of the file and how it works. This analysis typically involves looking at the file’s structure, the code and data contained in the file, and any strings that may be present. The analysis may also include looking at the functionality of the file and any other files or processes that it may interact with.

Chapter 3: Classification Analysis#

Classification analysis is an essential technique used in Malware Reverse Engineering for categorizing malware samples based on their structural and content-related characteristics. This process involves examining the properties and features of the file without executing it or disassembling its code.

Chapter 4: Dynamic Analysis#

Dynamic analysis is a crucial technique used in Malware Reverse Engineering for examining the behavior of malware samples in a controlled environment. Unlike static analysis, which involves examining the properties of a file without executing it, dynamic analysis involves executing the sample in a sandboxed environment to observe its behavior and interactions with the system.

Chapter 5: Static Analysis#

In this section of the video course, you will learn about the various tools and techniques used for static analysis, such as disassemblers, decompilers, and hex editors. We will also discuss how to analyze different aspects of a file, including its file header, strings, and code segments. By the end of this section, you will have a strong understanding of how to perform static analysis on malware samples and identify potential threats to the system.

Chapter 6: Windows Internals#

In this section, we delve into Windows Internals from the perspective of reverse engineering. Gain a deep understanding of the internal mechanisms and structures of the Windows operating system, focusing specifically on how they can be leveraged for reverse engineering purposes. Explore key concepts such as process and thread management, memory allocation, DLL injection, hooking, and more. By uncovering the inner workings of Windows, you’ll develop the knowledge and skills necessary to analyze and manipulate software at a low-level, opening up a whole new world of possibilities for reverse engineering and vulnerability research.

Chapter 7: Windows Programming#

In this section of the course, we’ll delve into Low-Level Windows Programming, focusing on Win32 APIs. This will help you understand the basics of how Windows works and how to interact with it using these programming tools. It’s a foundational step if you’re interested in exploring the intricacies of Windows programming.


Reverse engineering techniques can be applied to any system, but are commonly used on software and hardware. There are a variety of reverse engineering techniques, each with its own strengths and weaknesses.

Analyzing Portable Executable (PE) Files#

The Portable Executable Format is a file format used for executables, object code, and DLLs. This format is used for 32-bit and 64-bit versions of Windows. The format is also known as PE32 (for 32-bit) and PE32+ (for 64-bit). The format is designed for use in Windows, and can be used by other operating systems.

Dynamic Analysis Techniques#

Dynamic analysis is the process of reverse engineering a software program by observing its behavior at runtime. This can be done by running the program in a debugger and observing its execution, or by instrumenting the program to log its behavior. Dynamic analysis can be used to understand how a program works, to find bugs, or to perform security analysis.

Static Analysis Techniques#

Static analysis techniques are used in reverse engineering in order to understand the structure and function of a given system. By analyzing the code and data of a given system, reverse engineers can better understand how the system works and identify potential security vulnerabilities. Static analysis techniques can be used to reverse engineer any type of system, including software, hardware, and firmware.

Malware Injection Techniques#

Malware Injection Techniques are used by attackers to insert malicious code into a legitimate process or file. This allows them to gain control of the system and perform various tasks, such as stealing data, launching denial of service attacks, or creating a backdoor. There are several ways to inject malware, including buffer overflows, process injection, and DLL injection. Attackers often use these techniques to exploit vulnerabilities in software and gain access to systems.


There are a number of different tools that can be used for reverse engineering. These tools can be used to decompile code, to extract information from binaries, and to analyze data. Reverse engineering tools can be used to understand how a system works, to find vulnerabilities, and to create new programs that work with the system.


YARA is a powerful tool for reverse engineering malware. It can be used to identify and classify malware, and to find and extract specific features from malware samples. YARA can also be used to create signatures that can be used to detect and block malware.
