Malware Development
Malware Development I: Foundations
Learn to build offensive security tools the way professionals do.
This course teaches the fundamentals of Windows-based payload development. You will learn Windows internals and how to use them to build your own malware. You'll understand how process injection works, write position-independent shellcode, implement basic persistence mechanisms, and set up command-and-control infrastructure.
Everything is hands-on. By the end, you'll have built a working implant from scratch.
**What you'll build:**
- Custom shellcode loaders
- Process injection techniques
- Registry and scheduled task persistence
- Basic C2 beacon communication
**What you'll learn:**
- Core Windows internals relevant for offensive operations, including process memory layout, threads, modules, and execution flow
- How Windows APIs, syscalls, and user-mode vs kernel-mode boundaries affect payload execution
- How shellcode works at a low level, including position-independent code, stack manipulation, and API resolution
- Multiple process injection strategies and when to use each
- How malware achieves persistence on Windows systems
**Prerequisites:**
C or C++ programming experience. Familiarity with Windows API is helpful but not required.
**Note:** Content is intended for authorized penetration testing and security research only.
