Stopping Stealthy Radio Jamming in Industrial 5G: When the Air Interface Becomes the Attack Surface

In this episode of Cybersecurity Under Pressure: Real Attacks, Real Lessons, we explore a risk that is often underestimated in industrial 5G environments: stealthy radio jamming.Industrial 5G is usually presented as a driver for uptime, low latency, automation and flexible production. But once wireless connectivity supports mobile robots, AGVs, sensors, remote operations or safety-relevant workflows, the radio layer becomes part of the industrial risk model.The episode looks at how attackers may not need to fully disconnect a factory to create impact. Subtle interference, selective jamming, signal degradation or disruption of specific cells can create intermittent failures, delayed commands, false troubleshooting paths and operational uncertainty.The key lesson is clear: industrial 5G resilience cannot rely only on encryption, authentication or core network security. Organisations need spectrum monitoring, anomaly detection, coverage planning, fallback procedures, supplier accountability and incident response playbooks that treat radio interference as a real OT security scenario.
