New “Glowworm attack” recovers audio from devices’ power LEDs (4 minute read)

Glowworm is a passive attack that converts the fluctuations in LED signal strength into audio signals. The fluctuations aren't perceptible to the naked eye, but they can be read with a photodiode coupled to a simple optical telescope up to 35 meters away. Glowworm can only decode audio signals from electronic systems, so it can't be used to spy on real-world conversations. The attack requires a clean line of sight to the target system's LEDs. It won't work with a recording of the LEDs as even a high-definition close-up video would barely be able to capture the fluctuations. A link to the full research paper is available in the article.
