"Any sound in the room can be recovered from the room with no requirement to hack anything and no device in the room.”
cybersecurity researchers has discovered an absurd way of eavesdropping on conversations—through lightbulbs. A group of researchers in Israel introduced a new technique that allows eavesdroppers to spy on conversations by watching a light bulb hanging in the room from a nearby location.
This technique, dubbed as “Lamphone Attack”, shows that a conversation can be eavesdropped from about 25 metres (82 feet) away if there is a hanging light bulb near the location of the conversation. It works by detecting vibrations produced from bulbs due to the fluctuation of air pressure caused by the sound waves. When the sound waves hit the surface of the room, it triggers small vibrations that can be picked up through an electro-optical sensor focused at the bulb, say the scientists. This can then be used to pick up a conversation.
To achieve this, the setup consists of a telescope to provide a close-up view of the room containing the bulb. The electro-optical sensor is mounted on the telescope to convert light into an electrical current. An analog-to-digital converter transforms the sensor output to a digital signal, and then, a laptop processes incoming optical signals and outputs the recovered sound data.

So far you gotta be 82 feet away only, but just goes to show you never know what is listening.

just imagine what else they could do....
