When the UE Turns Adversary: Real-Time Uplink Jamming from Within 5G Networks (opens in new tab)

This paper presents an investigation of a novel class of stealthy and selective reactive jamming attacks targeting the Physical Uplink Shared Channel (PUSCH) in 5G New Radio (NR) networks. We design and implement STORM-RJ (Stealthy Timing Obstruction and Radio Manipulation -- Reactive Jamming), a Software-Defined Radio (SDR)-based adversarial framework that enables highly precise, time-frequency aligned interference by dynamically adapting the b...
