What risks could a WiFi hotspot on an air purifier expose if it's not connected to the network or a computer?
To be able to... know if your target's house has a lot of pollutants? Is particularly warm? There is practically no useful information that can't be gleamed by just looking through their windows, blinds and all.
> and the device could also be used as a hopping point for exploiting other devices in your home.
It's not connected to your home network, that's the whole reason for the hotspot existing. How, exactly, could it be used as a hopping off point, except to other devices with hotspots that... can just be exploited in the first place.
Please, explain exactly what sensor fusion would get you actionable data out of the PM2.5 sensor and "gas sensor" in a Philips smart air purifier.
I mean, sure, but who is going to do that when they can... look to see when people are home.
If the burglar only takes a 30 second look before breaking in, residents could be home but away from a window, with this the burglar can more confidently know when is a good time to break in, without exposing themselves to the same risk that looking around the house brings.
It's not even far fetched, smart watches reporting physical actively at unexpected hours have revealed infidelity in the past.
Stuxnet also sounded like a completely made up scenario.
As someone said, you lack imagination. And that’s OK, but you’re also being quite arrogant, too.
I have plenty of imagination. I also am practical and realize how illogical the argument of “sensor fusion” is to do something you can just use your eyes for.
Nobody is going to go out of their way to do this when KISS methods already exist and y’all don’t seem to understand practicality if you don’t see that.
If the hardware is fail safe I guess it can waste electricity.
