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!
Ok, now move your monitoring equipment outside your home, into a van parked across the street.
How trivial is it now?
Have someone swap out your monitor for a different random model so that you don’t know what it is.
How trivial is it now?
There are four screens in the room that I am typing this and another in a room a few meters away. You now need to isolate the rf bleed of one from all the rest.

I am now using my laptop at the local library where there are about 100 screens of various pcs and laptops.

That is my point. When you have actual physical access to the equipment in a controlled environment, stuff like this is relatively easy.
When you don’t and need to do it in an actual real world scenario where you want to keep the target unaware of what you are doing it becomes so hard that unless a nation state is watching you it will never happen.
It is not paranoia to investigate this.
Believing you need to secure yourself? Yeah that is moving towards paranoia.
Paranoia, on some level is an aspect of narcissism.
I am so special that others want to know what I am trying to hide.
Trust me, no one gives a shit.
