What do they see? Do they see your device name eg. "Craig's iPhone", or do they just see random alphanumeric characters?

> What is controversial about this? I'll predict that almost no one opted out of this for the simple reason that they didn't know this feature even existed. This is the "Hitchhiker's guide to the galaxy" method of faking consent.
They show it clearly above the slider when shutting down. Since this is a feature virtually 100% of users want on. This seems appropriate.

#154With this feature enabled, can adversaries (with a bluetooth antenna) detect your phone's presence, even if it's off? What do they see? Do they see your device name eg. "Craig's iPhone", or do they just see random alphanumeric characters?

> I’ll be pretty shocked if I’m “spied on” with this style of device. Why? There's plenty of devices in the wild constantly looking for wifi connection attempts, BLE Scans. Even cellular provider track locations in real-time by logging what cell towers you're using and associated signal strength. Just search for a place in google maps, and note the "Popular Times". How do you think they got that data :D
Um they get that data from being a monopoly and knowing when most people are looking up directions to or information about a location. Sure, they might do some other stuff to expand the data but there's much more relevant data right in their first-party domain.

#156Yep, that's not going to spark conspiracy theories and damage the brand at all, just like the backdoor they've recently put in. /s Again, why would $3T company damage its brand like that? It's not "for children" and certainly not to "find your phone". There's something going on there.
Apple has made it easier for users to locate lost (by being misplaced, forgotten, or stolen) devices with a feature that the user can opt out of on a temporary or permanent basis. What is controversial about this?

Why would they waste their time on Bluetooth tracking when your location pings cell towers and WiFi hotspots?
Perhaps because the bluetooth tracking is a lot more accurate. But since not even Apple can access the data (or so they claim), this shouldn’t be useful for surveillance.
UWB and Cell tower tracking are much more accurate for the majority of real-world applications

#158Can a faraday cage backpack work well to block any of this stuffv
Some of it. There is still the ultrasonic channel: beacons are emitted by various tv's, stores, etc. which can be used to capture location and other data and exfiltrate from the phone with the right software running. And of course the regular microphone can capture conversations and media. If the bag is not opaque, there is still an optical channel. Plus there are still accelerometers and magnetometers which can do r…
Re: Always-on Processor magic: How Find My works while iPhone is powered off
#159Very interesting read. This seems to be implemented as a Bluetooth LE app running on the ultra-low power “always on processor” used for a variety of features, like “wake-up on motion.” Much like an Tile or AirTag is implemented. No comment on what this is capable in the future.. but for now this shows power usage / signal strength / proximity of other “actually on” devices are a limitations of this feature. What’s im…

#160Now that would be useful. I guess this use case is valid when someone naughty finds your phone and turns it off to try and hide it?
