If I know someone on Signal I can now check if they’ve left the country.
Or send this to a bunch of signal users whom you suspect one of them being a particular person, and if you know that the person you are looking for is going to travel you can send it once before and once after. Then see which of these users were in the home city and subsequently in the destination city.
- sojournerc 2y agoA VPN obfuscates this. Assuming a target is even remotely aware, you might think they are in Australia, while they're actually in Nova Scotia
- iforgot22 2y agoSay I send a message to someone who has a phone with push notifications enabled, showing message previews. Will the phone still be connected to the VPN when it wakes up to display the message? Because my iPhone doesn't seem to stay connected to my VPN when it sleeps, at least not reliably. There really should be a "never use the internet without VPN" mode on devices.
- sojournerc 2y agoValid point. Afaict, vpns I've used route all network activity regardless of phone state, but that's likely dependant on the service.
- iforgot22 2y agoI don't see how that can work for the push packet itself, cause I thought that's specially handled by some low-power hardware on the phone while the main parts are shut off. Unless that hardware is also managing the VPN connection, which I doubt. So if there's no always-on hardware maintaining that VPN connection, probably the phone is going to wake up without it. And even if it auto-reconnects, it'll probably load stuff before it's connected to the VPN.
- sojournerc 2y agoYeah, probably only if mobile data is turned off so the packet doesn't hit the mobile network, and only wifi calling /messaging could the VPN hide location.
- akimbostrawman 2y agoThat exists on Android. VPN on ios is known to be rather leaky.
