Good additions, thanks.
Modern phones rotate random MAC addresses
My phone does, but im not sure if normal google/apple phones do by default.
Comment on Going to a Protest? Don't Bring Your Phone Without Doing This First
sobchak@programming.dev 2 weeks agoModern phones rotate random MAC addresses. For WiFi, capturing SSID probes can be enough to track somebody though (some phones also have some mitigation for that too, like not probing for an SSID after it hasn’t been seen for some amount of time). Even when turned off, many phones, including iPhones, turn into BLE beacons similar to AirTags, which can be used to track you.

iPhones do by default, you need to specifically turn on fixed IP at home to identify the damn phone reliably

almost worthless. I just learned that the android 13 xiaomi phone of a family member broadcasts some of the wifi AP names it knows when scanning for available networks! constantly! why the fuck it does I don’t know because neither are hidden networks that would need this, and there’s no setting for it

Yeah, I’m guessing it’s so if you “hide” the network, it will still connect to it. Anyone can scan these advertisements, then go to wigle.net and likely get a good idea of where you live/work.

Are those networks marked as hidden SSID networks? Hidden networks require the client STA to broadcast them to find them.

they aren’t. one of them is an AP from another phone, so I believe that one couldn’t even be configured as hidden by accident, because the phone does not offer it. another is one I sometimes use, and it’s not hidden either.
