Mitigating factor 1: The attacker would have to be close to the victim. The RF spec says 20 feet, but we all know that can be extended with a directional antenna and a high power radio. That’s still way less bad than if it’s vulnerable across the Internet. Physical isolation.
Mitigating factor 2: The device is only vulnerable temporarily, when it tries to connect with the monitoring station. It’s unclear how frequent this is, but it’s not all the time. Time isolation.
