Wait for people to learn about that you can listen in virtually anywhere through fiber-optic cables, as sound waves are enough to redirect the light in the cable to a measurable degree by "bending" the cable itself. Special devices to filter these variances out and transform them back to audio signals are a thing. It's only per line though, as any repeating device will just output a new cleaned up signal again.
Oh well, there have always been ways to snoop on someone like that. Back in the day it was CRTs emitting measurable waves through the neighborhood, with some papers even going as far as restoring the displayed image through a wall. Nowadays it's fiber and WiFi, and those seem to be much easier to work with even. Plus everyone carries a device that is tracked by their mobile provider's cell network. shrug
Just toss a doppler laser interferometer on a window, mirror, etc. At least with fiber-optics you need physical access. Single mode (I think that's most of FTTH) is pretty insensitive to vibration and hard to localize so you'd really have to install something.
As anyone observed who had a TV with just basic analog terrestrial antennas, before cable and satellite dishes - it does make a difference to the signal, when and where you stand and countless pieces of physical comedy in TV shows incorporated that.
Even having three security cameras around the perimeter of your house can allow quite precise location and activity detection inside the house via their audio steams.
I don't have security cameras in my house but that's actually interesting to see how things most people have in their house can (and does?) used to spy on them.
Yes. But depending who is doing the work they can just see what Bluetooth devices are around each hour of the day too...
It sucks that everything we have seems to be usable against us
If I ever try to hide (which is probably impossible at this time and age), I will probably just break my phone not like I can use it anyways every single act in it sends data to too many places to count.
I assume the problem is still tracing and association. So long as there is no direct link between you and the device, there is no saying if that is you or not. So grabbing a used phone via cash transaction from someone and only turning it on and using outside of your usual locations could be enough to have it being "anonymous". Then, using a vpn or other proxy that hides your network can make you very hard to find, so long as you don't associate with your real identity in any substantial form.
The danger with these technologies is not when they allow to precise track you once your general vicinity is known, that was always possible by putting some goons after you. General mass surveillance that is constantly tagged is the problem, flock, PRISM and the other stuffs.
Can't they already do that by snooping on ARP traffic on your home LAN? Failing that, if they can get whatever shitty wifi chipset they're using to enter promiscuous mode, they can also sniff all STAs that are in the vicinity, and with some ML they can probably figure out which MAC belongs to your phone.
π RuView turns commodity WiFi signals into real-time spatial intelligence, vital sign monitoring, and presence detection — all without a single pixel of video.
Just so anyone who reads this knows: This is a well known SCAM repo. The install instructions are incomplete and when you manage to get it running you will realize the data it produces is just random except for pre-recorded simulated data. If you check youtube for it you will find hundreds of completely AI generated Videos with not one of them showing the actual thing working. And all while trying to sell you some hardware.

So, a bad actor can now know when I'm at my house or not, I'm sure that's fine and won't be problematic

Those mics can be quite sensitive.

Really? They can’t seem to pick up a conversation happening directly in front of them.
Yes. But depending who is doing the work they can just see what Bluetooth devices are around each hour of the day too... It sucks that everything we have seems to be usable against us
They already knew this from your cell phone not being in airplane mode.
there is always the risk of the isolated Faraday caged house

Thank you for more paranoia

yeah, now I gotta unplug TV too

Now, about the wifi part, why isn't there an Home Assistant extension that detects already room presence magically exploiting all of this??
There is: https://community.home-assistant.io/t/espectre-wi-fi-motion-...
