Custom LoadLibrary WinAPI Function

The Custom LoadLibrary technique provides a stealthy way to load DLLs on Windows by bypassing the well-monitored LoadLibrary / LoadLibraryA/W APIs exported from kernel32.dll. Instead, it directly invokes the undocumented LdrLoadDll function from ntdll.dll (the core internal loader routine used by the Windows module loader) after preparing the DLL path with RtlInitUnicodeString. By dynamically resolving these low-level ntdll exports via GetProcAddress and calling them manually, the technique avoids user-mode hooks, API monitoring, and behavioral detections that most EDRs/AVs place on the standard Win32 loading path, making it particularly effective for loading malicious or red-team DLLs from unusual locations (e.g., %PUBLIC%, temp folders, or network shares) while requiring only user-level privileges and remaining relatively easy to implement in C++ or similar languages. Defenders can counter it by monitoring or hooking LdrLoadDll itself early in process lifetime or watching suspicious patterns of RtlInitUnicodeString followed by LdrLoadDll calls.
