   InjectEave Attack Lets Attackers Eavesdrop on Headphone Audio From 30 Meters Away

   cyberpress.org · 35d ago · September 8th, 2026

   A newly disclosed electromagnetic attack, dubbed InjectEave, can recover audio played through consumer headphones from as far as 30 meters away. Unlike conventional EM side-channel attacks that passively collect weak stray emissions, InjectEave actively transmits a tuned radio-frequency signal toward a target device to induce stronger, recoverable leakage. The technique was developed by researchers from the Hong Kong University of Science and Technology (Guangzhou) and the Hong Kong Polytechnic University. New InjectEave Attack Lets Attackers Eavesdrop Their paper, “Injected and Leaked: Actively Inducing Side-Channel Leakage Using Electromagnetic Injection and Hardware Nonlinearity,” was accepted at USENIX Security ’26. Traditional EM eavesdropping faces a major physics limitation. Speech and other audio signals generally occupy frequencies between 20 Hz and 20 kHz, whereas device wiring more efficiently radiates at much higher megahertz-to-gigahertz frequencies. Attacker Next Door (Source: Arxiv) As a result, previous passive attacks, including MagEar and Periscope, were generally limited to distances below 1.5 meters. InjectEave bypasses that limitation by transmitting an RF carrier that couples into a target’s internal circuitry. Nonlinear components, including audio amplifiers, analog-to-digital converters, power converters, and switching MOSFETs, unintentionally mix the target audio with the attacker’s carrier. The mixed signal is then re-radiated through wires, cables,

   Security researchers have unveiled InjectEave, an electromagnetic side-channel attack that can turn ordinary headphones into unintended transmitters. By directing radio-frequency energy at vulnerable hardware and collecting the resulting emissions, an attacker can reconstruct audio playing through a target device. In a long-range experiment using amplified equipment, researchers successfully recovered audible speech from wireless headphones at […] The post New InjectEave Attack Lets Hackers Eavesdrop on Headphone Audio From 30 Meters Away appeared first on GBHackers Security | #1 Globally Trusted Cyber Security News Platform .
