Comment on Going to a Protest? Don't Bring Your Phone Without Doing This First

Shitty article. Doesnt even contain the words SIM card or IMEI so it has no business advising people on whats safe to bring to a protest. There is no such thing as cop-proofing a mobile phone unless all wireless modules have been removed. The cops can and do track peoples cell tower signal derived locations and they can log Wifi/Bluetooth MAC addresses in their vicinity.

This is slightly false in an alarmist fashion. At least in the US, the police are not actively tracking anything without a subpoena to the cellular provider of the phone in question. They can look at the location data after the fact, using a court ordered subpoena. They can also use live location data in an emergency situation,also using a court ordered subpoena.
Cellular data from cell towers on cell networks are private property of the cellular provider companies. That’s not to say you are private while on them. Just that the police are not actively tracking your location through them without great effort for each individual they wish to track.

You’ve never heard of a stingray or cell site simulator?

Commercial location data, in this case acquired from hundreds of millions of phones via a company called Penlink, can be queried without a warrant, according to an internal ICE legal analysis shared with 404 Media.

I thought this was using SDKs embedded in apps and advertising platforms. This is a different threat model. You need to block ads and prefer using websites instead of apps which have more access to device info like the advertising ID.
If you’ve got an Android, go to Settings, search for ads, and find the advertising ID and delete the ID. It’s a stable identifier that can be used to identify your phone.

What qualifies as an “emergency situation”? I imagine that definition could be stretched pretty thinly

Cell tower data is private just like your google search history is private. Which means absolutely not private. Also cops can (and do) use fake cell towers to make your phone connect to something that they have live access to.

Modern 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.

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
chaospatterns@lemmy.world 8 hours ago
Are those networks marked as hidden SSID networks? Hidden networks require the client STA to broadcast them to find them.

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.

Good additions, thanks.
My phone does, but im not sure if normal google/apple phones do by default.
lepinkainen@lemmy.world 9 hours ago
iPhones do by default, you need to specifically turn on fixed IP at home to identify the damn phone reliably
