We assume that the USB splitter supplies power to some speakers. The power indicator LED of the USB splitter is connected directly to the power line, as a result, the intensity of the USB splitter's power indicator LED is correlative to its power consumption. The sound played by the connected speakers affects the USB splitter's power consumption and as a result is also correlative to the light intensity of the LED. By analyzing measurements obtained from an electro-optical sensor directed at the power indicator LED of the USB splitter, we can recover the sound played by the connected speakers."},{"lang":"es","value":"Los dispositivos splitter USB TP-Link UE330 hasta 09-08-2021, en determinados casos de uso en los que el dispositivo suministra energía a equipos de salida de audio, permiten a atacantes remotos recuperar las señales de voz de un LED del dispositivo, por medio de un telescopio y un sensor electro-óptico, también se conoce como un ataque \"Glowworm\". Suponemos que el divisor USB suministra energía a unos altavoces. El LED indicador de potencia del divisor USB está conectado directamente a la línea de alimentación, por lo que la intensidad del LED indicador de potencia del divisor USB es correlativa a su consumo de energía. El sonido reproducido por los altavoces conectados afecta al consumo de energía del divisor USB y, en consecuencia, también es correlativo a la intensidad luminosa del LED.
