      "value": "CREATIVE Pebble devices through 2021-08-09 allow remote attackers to recover speech signals from an LED on the device, via a telescope and an electro-optical sensor, aka a \"Glowworm\" attack. The power indicator LED of the speakers is connected directly to the power line, as a result, the intensity of a device's power indicator LED is correlative to the power consumption. The sound played by the speakers affects their power consumption and as a result is also correlative to the light intensity of the LEDs. By analyzing measurements obtained from an electro-optical sensor directed at the power indicator LEDs of the speakers, we can recover the sound played by them."

El LED indicador de potencia de los altavoces est\u00e1 conectado directamente a la l\u00ednea de alimentaci\u00f3n, por lo que la intensidad del LED indicador de potencia de un dispositivo es correlativa al consumo de energ\u00eda. El sonido reproducido por los altavoces afecta a su consumo de energ\u00eda y, en consecuencia, tambi\u00e9n es correlativo a la intensidad luminosa de los LED.
