Writing Custom Malware: Import Address Table Hooking
Source: YouTube · John Hammond · published Dec 7, 2023 · 48:54
This tutorial demonstrates how to create custom malware that can hook into other programs to monitor and manipulate file operations 0:00. The instructor walks through building a DLL that hijacks Windows API functions by modifying the Import Address Table (IAT) of executable files 10:00.
Key Takeaways:
• The video explains how PE (Portable Executable) files are structured with headers, sections, and data directories that can be navigated programmatically 1:49
• The tutorial shows how to implement IAT hooking by creating custom functions to replace Windows API calls like CreateFileW 14:00
• The process involves creating a DLL that can be injected into target processes using process injection techniques 10:15
• The instructor demonstrates how to create replacement functions for GetProcAddress and GetModuleHandle to avoid having the malware itself hooked 26:37
The tutorial provides a hands-on approach to understanding Windows executable file manipulation and malware development techniques.

let's create our own custom malware let's write malware that can hook into other programs applications and software and see what files other users create or write to and maybe even manipulate them modify them and tamper with the file contents so the user is completely unaware let's dive in so I'm going to open up visual studio because I want to create a compiled binary on Windows right the program and application itself should be an executable file or an EXE so we'll write this in C C++ we're going to end up renaming it all working with C but if we create just an empty project we'll go ahead and click next we can call this my malware and then we'll build it go ahead and click create now that Visual Studio is fired up let's make sure to set this to release mode x64bit architecture and I'll …
