## What it is
A collection of proof-of-concept C tools and reference data for understanding EDR/AV hooking on Windows, including syscall patching utilities and lists of hooked ntdll.dll APIs per vendor. It is aimed at red team operators researching endpoint detection evasion techniques.

## Use cases
- find which ntdll APIs an EDR hooks before an engagement
- dynamically resolve syscall IDs without knowing the Windows version
- unhook the Import Address Table to remove EDR hooks
- patch syscall numbers in ntdll to bypass userland hooks
- compare hooking techniques across CrowdStrike, SentinelOne, Cylance, and Sophos
- contribute hook_finder output to a community EDR dataset

## When to choose
- you are a red teamer researching EDR userland hooking on Windows
- you need reference lists of hooked APIs per EDR vendor
- you want working C proof-of-concepts for syscall patching and IAT unhooking

## When to avoid
- you need a production-ready evasion framework with maintenance and support
- you are defending endpoints and want a defensive detection tool
- you need something cross-platform or non-Windows

## Facets
- artifact type: learning-resource
- maturity: active
- function: security, reverse-engineering, developer-tools
- domain: security, penetration-testing, windows
- platform: windows, cpp
