Security researchers from The Hong Kong Polytechnic University, The Chinese University of Hong Kong, and the Technological and Higher Education Institute of Hong Kong have disclosed a critical side-channel attack that turns ordinary fiber optic internet cables into hidden. Researchers at NDSS 2026 demonstrate a covert acoustic eavesdropping attack that transforms standard FTTH telecom fiber cables into passive, undetectable listening devices invisible to RF scanners and immune to ultrasonic jammers. Security researchers from The Hong Kong Polytechnic University, The. ‼️🚨 NEW RESEARCH: Fiber-optic cables can be turned into a hidden microphone and used for eavesdropping. The paper was presented at NDSS 2026, one of the top cybersecurity conferences in the world. A fiber optic technique used to detect earthquakes can also pick up the faint vibrations of nearby speech, researchers reported this week here at the general assembly of the European Geosciences Union.
