Does anyone have experience with sound device hacking?. I have read many articles where frequencies can be used to transfer files and work to transfer files or malware. Very cutting edge technology. There seems to be little to no defense in these types of attacks.

The one incident that I saw was the introduction of malware on the remote computer that would generate sounds. The sounds were then located elsewhere in the room. This was listed as an out-of-band attack because it didn’t need a network connection between the target system and the attacker, and the writer indicated that air-gapping was not enough. However, when I think of air-gapping, I normally assume the use of filtered electrical power, acoustic and vibration damping, and blocking of visual and other electromagnetic radiation by using a Faraday cage.

I suppose another example would be that if “voice over” was turned on, a microphone could listen to the text.

I would be very interested if you could post references to the articles if they didn’t require insertion of malware on the target system and/or would work in an air-gapped situation.

I’m not being accusatory. The article that I read tried very hard to conceal the fact that it was using malware by using confusing wording.
