## What it is
The original C implementation of the Hell's Gate technique, which resolves Windows system call numbers at runtime to invoke NT APIs directly. It is a reference implementation accompanying a VXUG research paper on evading security monitoring.

## Use cases
- resolve syscall numbers dynamically in windows
- bypass edr api hooking for research
- direct syscalls in c for red team tooling
- learn how hells gate technique works
- study windows ntdll syscall resolution

## When to choose
- you are researching offensive security techniques or EDR evasion on Windows
- you need a minimal reference implementation of runtime syscall resolution in C

## When to avoid
- you need a supported, licensed library for production software
- you are building defensive tooling or benign Windows applications
- you need a maintained project with active development or releases

## Facets
- artifact type: library
- maturity: maintenance
- function: security, reverse-engineering
- domain: security, penetration-testing, windows
- platform: windows, cpp
- tags: syscalls, malware-research, edr-evasion, vx-technique, offensive-security, ntapi
