All of vehicles and many of other divides have CAN BUS that we don’t want to connect to them directly. So we can make a sensor to secretly listening without connecting to the CAN bus. we use the electromagnetic waves emanating from the CAN bus to listen to the information passing through the bus and reach it without connecting to the CAN bus.
