🔥 heap-playground
The Definitive Windows Heap Internals & Exploitation Suite
A PwnFuzz Flagship Research Project
heap-playground is a research-grade knowledge suite and practical playground that dissects the internals of Windows user-mode heap memory and its exploitation pathways on modern Windows systems (Windows 10+).
This repository is part of the debut initiative from PwnFuzz — dedicated to pushing the standards of exploit research, documentation, and tooling with battle-tested depth.
Objectives
- Provide a reproducible and documented reference implementation of user-mode heap internals
- Explain and demonstrate heap exploitation techniques still effective on modern systems
- Analyze the structure and flow of Windows user-mode heap mechanisms: NT Heap, Segment Heap, LFH on Windows10/11
- Cover all relevant mitigations implemented across OS versions (Windows 10 → latest)

Audience & Use Cases
This repository is designed for:
- Exploit Developers – crafting Windows heap exploits and understanding allocator behavior
- Security Researchers – analyzing OS-level mitigations and memory protections
- Reverse Engineers – diving deep into undocumented or barely-documented heap logic
- Learners – gaining hands-on experience with real-world allocators and PoCs
