They are a caramel for hackers

Use headphones With cable as a retransmission antenna. Sounds crazy, but it’s the New practice whereby the attackers can listen at a distance everything you are saying. Periscope is the new espionage system by electromagnetic radiation developed in the laboratory, in order to prove that the devices that are connected to this type of headset are vulnerable.

New research has deepened this method by which the sound can be intercepted that is being broadcast through laptops and mobile computers (both Android and iPhone).

The authors discovered that both phones and computers generate electromagnetic radiation When they process the sound signals. The funny thing is that, intercepting this signal, the original sound can be recovered.

Cable headphones They act as antennas, so they amplify this signalinterceptable up to 15 meters. These signals are imperfect, but can be cleaned with noise and distortion by computer. A complete reconstruction of the audio was achieved with 7.44% error, making audio intelligible both by humans and artificial intelligence.

What scenarios can this vulnerability be exploited? In anyone in which your device is broadcasting audio. For example, if you were in a meeting and say any confidential data, a laptop located in a range of 15 meters could intercept the signal and rebuild it later.

The researchers reported the problem to Apple, Lenovo, Huawei, Vivo, Oppo and Dell, ensuring that Huawei has been one of the first to get to work to develop a solution.

This vulnerability has been discovered in the laboratory, so, for the moment, it does not seem to have been tested in real scenarios at the hands of hackers.
