Codigo para cargar Drivers en el kernel

[dapz]

Mi pequeño Loader, que hace :
1-) registrar un servicio y ejecutarlo
2-) detener un servicio y eliminarlo

Loader:

Codigo del Driver

Código (c) [Seleccionar] Expandir

#include <ntddk.h>


VOID Unload(PDRIVER_OBJECT DriverObject)
{
DbgPrint("Driver Unloaded From Memory\n");
}

NTSTATUS DriverEntry(PDRIVER_OBJECT DriverObject, PUNICODE_STRING RegisterPath)
{
DbgPrint("Hellow World From Kernel Space\n");
DriverObject->DriverUnload = Unload;  // No siempre hay que limpiar el codigo , pero si es recomendable si vamos a hacer pruebas, ya que , de lo contrario hay que reiniciar el ordenador continuamente
return STATUS_SUCCESS;
