It irks me that the onus of not being tracked is on the "target" themselves. Further, there's no protection if you have no smartphone but are in a dense population area surrounded by devices that are part of this surveillance network. There is no aspect of this that is privacy friendly except for the hand waving.

There’s protection even if you’re standing there naked (except for the AirTag, of course, that has been secretly duct-taped to your buttocks): if the paired phone isn’t around, the AirTag makes noise. I can confirm this because my spouse is currently out of town, and I’ve grabbed her RV keys a couple of times to put stuff in the RV. And every time I pick the keys up, the AirTag goes off. It eventually shuts up just s…

Unless someone piggybacks on Apple’s find my network using their own hardware.

I read the specification and turned my laptop into an airtag clone one day I was particularly bored, really isn’t complicated.

Why annoy people like this? My e-bike has Find My tracking built in to the firmware. As long as you don’t steal my bike you have no privacy concerns from me securing my bike. Even better I can track my bike down without involving the police, so the potential thief doesn’t even have to worry about being shot by some trigger happy cop.

Is “cop shoots bike thief” something you actually think is common enough to note? This implies a concerning reality departure.

Depends on the colour of the skin of the bike thief, but cop shoots innocent driver seems fairly common

This is something Apple should be providing themselves (edit: for Android). They already have "Apple TV", "Apple Music", and a "Move to iOS" app. Is it really so much to ask for a stalking prevention app?

This already is the case. iOS alerts you of any airtag it detects for a long enough time.

Please explain to me how a thief is going to use the existence of this tech to enable theft.

I think their point is that knowing there’s an air tag on something nearby indicates it’s probably something of value worth stealing.

How often is that something otherwise invisible, however? Like if I put one on my bike are there really many thieves who would otherwise not have considered it? I’m sure there are some small things which are relatively covert but it seems like a relatively uncommon situation.

A blanket ban on hoarding, storing and selling personal data for any purposes other than natsec. Basically, treat personal data like nuclear materials in the laws.

I wasn't onboard at first, but I actually think that's a pretty reasonable take to have on it. Apple should be allowed to implement Find My, but only as an open standard that other manufacturers can implement so they can also have safety features. Simply notifying every iPhone isn't going to stop someone from putting it in a kid's backpack, tracking your vehicle, or any other obvious edge case. There are lots of solu…

As of spring 2021 they actually opened up the Find My spec for third party manufacturers [1] - that’s how those electronic bikes and headphones can have built-in Find My tracking now.

Since this app is for Android and the Apple apps mentioned by the parent comment are for Android, I think he's saying Apple should be the ones providing their own AirTag app for Android, not university students.

Pretty cool but why does it have to be limited to AirTag or any specific devices? It would be easy to expand it to keep track of any nearby Bluetooth device and a corresponding whitelist. (Or do AirTag devices rotate Bluetooth MACs?) Airtags are just one implementation of a Bluetooth transmitter and a long life battery but anyone could probably build a similar device dedicated to tracking with off the shelf parts.

Airtags are the only devices (that I know of) that can leverage a worldwide network of iPhones to transmit their location rather than a power intensive LTE or GSM link. They also don't require any external antennae for location determination like those GPS trackers stalkers use. Those features make make AirTags more practical for any use, good or bad. They do rotate Bluetooth MAC addresses so only you and Apple can f…

A prominent group of Virtual YouTubers (whose talents use avatars and keep their real identities anonymous) recently needed to stop allowing fans to send gifts to talents, despite them always having been screened, because the gifts might contain AirTags that could ping the sender when they arrive ina talent’s home. It’s not that this wasn’t possible before, but it suddenly became easy for a would-be stalker to execute the attack.

A tool like this that reliably detects AirTags rather than relying on whatever heuristics Apple uses to say “an AirTag is following you” would be invaluable for people’s opsec, be they performers or journalists or anyone else desiring anonymity.

Seems so, there’s a constant named AIR_TAG_SOUND_CHARACTERISTIC with this value: 7DFC9001-7D1C-4951-86AA-8D9728F8D66C

The small evil part of me wants to extract this part of the source and just bring my phone onto public transit for a while to see what happens.

Now I'm curious too - if you decide to do it, let me know :D

> With the app you can play a sound on AirTags and find it easily. I wonder how it does that. Unauthenticated BLE characteristic? This would imply anyone could force an arbitrary AirTag to make a sound. Obvious application: force all AirTags nearby to keep making sounds.

What if someone else is tracking your bike? Or backpack, or car, etc? GPS trackers exist so this doesn't eliminate that concern, but at least if someone tries tracking you with an AirTag you have an option to locate it.

Feel free to steal my daughter's water bottle. I don't track it because it's valuable, I track it because she's irresponsible.
