Kernel-Mode Protection
Luys operates through a custom-built kernel driver at Ring 0 — the highest privilege level on Windows. Kernel-mode software runs below user-mode applications, including games and their anti-cheat scanners.
Anti-cheats like VAC that only scan in user mode cannot detect or inspect kernel-level drivers. This is what makes Luys safe on all official Valve matchmaking — Premier, competitive, and casual.
Luys has no in-game client. There are no injected menus, no overlays inside CS2, and nothing that modifies the game window directly.
