Hi, in your article I noticed that the pairing procedure is:
When paring an AirTag with an Apple Device, an Elliptic Curve key pair is generated and the public key is pushed to the AirTag (and a shared secret to generate rolling public keys)

I’m confused about whether the private key will be stored in the airtag, because from the paper https://arxiv.org/pdf/2103.02282.pdf section 6.1, it seems that if you don’t know the d_i then you can’t calculate the next p_i?

Would be appreciated if you can clarify this 🤣 thanks!

Hello
On Ubuntu with ESP32 WRoom When run idf.py build. I get the following error :

I tried fresh installing multiple times. I tried multiple computers and multiple Operating systems ( Ubuntu, Kali, MACOS)

Is it possible to compile the app with greater compatibility for older versions? I'm running 10.11.6 on an old iMac and when I run the OFFetchReports app it says "The application requires OS X 10.15 or later."

Thanks.

The DataFetcher window doesn't allow me to scroll, so I'm not able to load more than the first 25 or so messages. Is this fixable?

Hello there, I compiled the esp32 project, and also ran the osx project, (just updated to xcode 14.x) both look to be running, however I have my doubts, i see that there are a lot of messages:

[0;32mI (1979) findmy_modem:   pub key to use (3. try): ba be 00 00 00 0d 00 00 00 00 81 81 81 81 00 00 00 02 00 00 00 00 00 00 00 00 00 … 01�[0m
�[0;32mI (2019) findmy_modem:   pub key to use (1. try): ba be 00 00 00 0e 00 00 00 00 81 81 81 81 00 00 00 00 00 00 00 00 00 00 00 00 00 … 00�[0m
�[0;33mW (2059) findmy_modem: Generated public key tested as invalid�[0m
�[0;33mW (2079) findmy_modem: Generated public key tested as invalid�[0m

I noticed that in fact I get the "message" to the other side, so I am wondering this:

1. the message is sent 1 byte at a time from what i can see in the code, right? so every adv key has let's say 1 letter and it continuously advertises several letters until it fully reads something on the other side?
2. how come it test keys as invalid, does it need valid keys? (this is the part I didnt quite understand)

and finally thank you for your example, great work!

I recently ported your ESP32 Send My firmware to Zephyr and I'm running it on an nRF52832-based RuuviTag, sending the temperature values of the built-in BME280 to the Find My network (see the send-my-sensor project I just published). I'm barely able to receive messages in the DataFetcher, most of the shown characters are ?, with an occasional character coming through completely. I verified that the BLE packet capture is identical to the one sent by the ESP32 firmware for a test message. But my household is very low on Apple devices, just one Mac Mini M1. Does this only work with multiple Apple devices in the neighbourhood?

It's very strange

Hi,

going beyond starring your repo, to tell you: that's just really amazing example of pwning / abusing Apple protocols :)

You are doing great job! That's also in general about Positive Security !

Best regards,
Peter
