48 分钟Hello, and welcome to another Working from Home episode of No Such Thing as a Fish,
a weekly podcast coming to you from four undisclosed locations in the UK.
My name is Dan Schreiber, I am sitting here with James Harkin, Andrew Hunter Murray, Anna Tijinski,
and once again we have gathered round the microphones with our four favourite facts from the last seven days,
and in no particular order, here we go.
Starting with you, Andy.
My fact is that spies can tell what people are saying by looking at the lights in the room they're in.
So, this is a new spying technique which has been discovered, or I don't know what you do as spying techniques,
but it's been found out by researchers from the Ben Gurion University of the Negev and the Weizmann Institute of Science.
And what they've found is that there are lots of different ways of eavesdropping on people,
and this one is called LAMPHONE.
And what it means is if we're all talking in our rooms, if there's a light bulb, and it has to be a hanging light bulb,
so you know, a classic bulb, your conversation will make tiny,
tiny vibrations on the surface, and that will slightly affect the light inside the bulb.
And you can get very cheap equipment, like it costs a couple of hundred dollars,
and you just observe the light bulb from outside the room, and you can pick up what people are talking about.
You can decode speeches.
Can you reach us?
Yeah, so you can, it's not like Morse, it's not translating into Morse, you can pick up the actual sound?
Well, I think it has to be translated from light bulb language into sound.
