This alone wouldn't be enough sure. But you can get more data to say that it isn't doing any RF by looking at the circuit board and looking for antennas, they've got some fairly distinct shapes to be able to radiate efficiently. Of course they could still be inefficient radiators on purpose to prevent them from being found, but that also then means that they'd have to be even closer to pick up the signal. You can take xrays of the board to confirm the construction matches the schematics you can find from various websites (i don't know them myself, but I know repair shops get them). You can then decap the chip to examine it for any intentional radiators, which you'd need at that scale to be able to get any signal out. All that combined with a metal case, and you're unlikely to sneak in a transmitter that way. It'd be far easier to compromise the wifi firmware which is a binary blob anyway, and just use it to dma data off main ram directly. It's already built to do it, and it's got antennas that are expected already. |
