How do I learn more about using RF to improve my privacy? (lemmy.world)

Hi, I have been having a look at utilising RF and trying to understand how every device around me emits RF.

I recently came across RTL-SDR and HackRF, alongside software like SDR++, TempestSDR, gqrx etc. I know that I can spy on my monitor and record keyboard keys being pressed using RF, but what are some other ways I should be looking at to exploit my digital vulnerabilities, and trying to solve such problems?

Thanks!

Edit: I'm well aware that nothing I'm doing is that interesting to security agencies across the globe. With that said, I'm interested in maintaining my privacy, and this happens to be an avenue I find interesting. Any suggestions on how I can look to do so would be greatly appreciated!

I understand your point, although I do not believe that I'm much of a narcissistic person.

I also do realise that it is not trivial for a random person to spy on me - thank you for the example.

With that said, I do still want to know. Regardless of whether I think I'm special, that I have something to hide, or if I'm paranoid. Could you point me in the right direction?

Honestly, if you are serious about limiting RF leakage. The simplest and easiest avenue I can suggest is to build a faraday cage around you equipment.

No expensive testing equipment required.

It won't be pretty or convenient but a couple of hundreds dollars in 2 by 4s and chicken wire will block out your theoretical neighbour from scanning from the apartment above, below or from any direction.

Of course that will mean you can't use WIFI but I assume you know that already.

don't use 2x4s. Furring strips are way cheaper and would take up less of the interior space while doing the job just as well.

But yeah, it's also ~~dumb~~ pointless, so don't do that.

Thanks, I was thinking the same thing. But how would I build a Faraday-cage for a bunch of cables? Say, the HDMI cable to my monitor and the USB cable to my keyboard.

Why would this hamper my usage of WiFi though? I'm going to be using WPA3 very soon, at which point trying to hack into it becomes quite arduous and I suppose nobody but nation states have undisclosed backdoors for such marvellous technology.
