MALFORGE is a meticulously structured repository of Windows API implementations, organized according to industry-standard malware analysis taxonomy. This project serves as a comprehensive reference implementation for security researchers, malware analysts, red team operators, and defensive security engineers.
MALFORGE provides:
- Production-Quality Code: Well-documented, compilable C implementations of security-relevant Windows APIs.
- Taxonomic Organization: Structured by MITRE ATT&CK and MALAPI.io categorizations.
- Dual-Purpose Design: Supports both offensive security research and defensive mechanism development.
- Educational Foundation: Deep-dive technical documentation for learning Windows internals and security concepts.
This repository is built on three core principles:
- Transparency: Open-source implementations that demystify complex security techniques.
- Education: Comprehensive documentation to facilitate learning and understanding.
- Responsibility: Clear ethical guidelines and responsible disclosure practices.
