DEMO: Illuminating the BlindSpot: Efficient Single-Node Selective Jamming for LoRaWAN

LoRaWAN has become a widely adopted, cost-effective solution for Low-Power Wide-Area Networks (LPWANs), bridging the gap between short-range wireless protocols and high-power cellular networks. Its affordable hardware and robust physical layer make it a key enabler for Internet of Things (IoT) applications across sectors like agriculture, smart cities, and industrial automation-domains where security is of central importance. Investigating LoRaWAN's resilience against physical-layer attacks, we developed BlindSpot, a novel jamming attack targeting state-of-the-art LoRaWAN gateways. Unlike traditional jammers, BlindSpot does not rely on overpowering transmissions but prevents their reception by exhausting resources at the gateway. This is possible since commercial gateway processors have only a limited number of demodulators for parallel frame reception. In this demo, we show the effectiveness of the attack against a commercial LoRaWAN gateway, compare it to traditional jamming, and show how our Software-Defined Radio (SDR)-based receiver can overcome the attack.
