XC3 attempts to hook User-Mode APIs to monitor calls made by potential cheats. A bypass involves using unhooked versions of these libraries.

Modern Xigncode3 enumerates all running threads every 500ms. If a thread exists that is not signed by Microsoft or the game publisher, and it attempts to call NtReadVirtualMemory on the game process, the thread is terminated. Cheat Engine’s VEH (Vectored Exception Handler) debugger method relies on creating new threads—immediately detectable.
