Umium

Umium is a security-focused anti-debugging and anti-reverse engineering library designed for high-resilience Windows 10/11 x64 applications. It uses a combination of undocumented Windows NT system functions and advanced runtime modifications to detect and neutralize debugging, memory tampering, or sandboxing attempts.

Usage

Umium is a single-header library. Drop umium.hpp into your project.

In exactly one .cpp file, define UMIUM_IMPLEMENTATION before including the header:

// main.cpp (or any single TU)
#define UMIUM_IMPLEMENTATION
#include "umium.hpp"

int main()
{
    umium::get().start();
    // ...
}

Every other translation unit that only needs the type:

#include "umium.hpp"

No separate compilation step, no static/shared library — just the header.

Requirements

• Windows 10 / 11, x86-64 only
• Compiler: Clang (trunk) or MSVC with C++20+; C++26 recommended
