Tetanus

Windows Detouring Library in Rust

x86 · x64 · ARM · ARM64

Tetanus is a lightweight Windows user-mode function hooking library written in Rust, providing inline detours and related hooking techniques across all major Windows architectures.

Inspired by MinHook, Tetanus reimplements its core behavior in idiomatic Rust, with added ARM support and a modular, safety-focused design.

Features

Inline detours with trampolines (MinHook-like)
Enable / disable hooks at runtime
Original function access via trampoline
Architecture-aware instruction patching
Safe for use in injected or external DLLs

Supported Architectures

x86 (32-bit)
x64 (64-bit)
ARM32 (Windows on ARM)
ARM64 (Windows on ARM64)

Hooking Techniques

Inline detours
IAT (Import Address Table) hooking
EAT (Export Address Table) hooking
VEH (Vectored Exception Handler) hooks

Design Goals

Correctness over cleverness
Explicit and well-documented unsafe code
Clear hook lifecycle management
No MinHook source reuse
