Researchers found a way to eavesdrop on headphones from 30 meters away, and encryption can’t stop it
The big picture: Researchers in Hong Kong have developed a technique that uses injected radio signals to extract audio and other information from headphones, phones and smart-home devices. Called InjectEave, the method targets analog components that can leak signals too weak to capture through conventional electromagnetic eavesdropping. In testing, the researchers recovered understandable headphone audio […]
