Researchers Develop Method to Eavesdrop on Headphones from Afar

Researchers in China have developed a technique to eavesdrop on signals from analog components in devices like headphones and smart devices by injecting electromagnetic (EM) signals. This method, known as InjectEave, overcomes challenges posed by weak RF signals, allowing attackers to potentially capture audio from headphones up to 30 meters away. The implications for privacy and security are significant, especially in everyday consumer devices.
