i think the other direction it would work too - generating HDD head movements in a way to encode info in the resulting noise - taken together with the OP it means that one can cross the air gap in both directions (the Cuban sounds look more and more like an electronic attack with humans being just an unfortunate collateral). Similar things can probably be done with the CPU/case fans - thus for example a "bad" motherboard can talk and listen to the world.
- userbinator 7y agogenerating HDD head movements in a way to encode info in the resulting noise That's not so interesting, as anyone who has used a machine with an audible hard drive knows --- you can tell whether the system is idle, working, or doing something strange ("I'm not doing anything that would write to the disk, why is it still grinding?") just by the sound.
- trhway 7y agoyou can encode it into a normally working mode - say by slightly varying timings of head movements during legit disk ops, kind of frequency coding.
- anticensor 7y agoThat would be an interesting advancement.
