OpenHaystack: Tracking Personal 'AirTags' via Apple's Find My Network
- mensetmanusman 6y agoStart enabling ipv6 on your routers, these iot devices are going to break ipv4.
- Solocomplex 6y agoIt breaks a lot of cheap IOT devices without 6to4 translation
- jon-wood 6y agoThese devices don’t have a network connection, tracking is done via BLE which just broadcasts a beacon regularly and is then picked up by nearby Apple devices which do have a connection.
- tinus_hn 6y agoHow does Apple prevent me from using this to track random people based for instance on their Bluetooth headphones?
- bberenberg 6y agoYou would have to flash their headphones with custom firmware to do this. Take a look at https://github.com/seemoo-lab/openhaystack#how-does-apples-find-my-network-work https://github.com/seemoo-lab/openhaystack#how-does-apples-f...
- tinus_hn 6y agoAll right, so it isn’t normal Bluetooth devices but requires a special feature in the device.
- ArchOversight 6y agoIf you are within BLE range you can "track" someone, but that is already the case with wifi/bluetooth in general. Even known the public key, you can download the encrypted reports from Apple, but since you don't have the private key you can't decrypt the location messages.
- AlotOfReading 6y agoThat's why devices that aren't intended to be beacons are supposed to enable address randomization. It still has some security issues and undirected advertising of unique public keys obviously defeats the point, but it's more difficult to track than classic devices were.

- filleokus 6y agoAwesome work! I can recommend people interested in the iOS/Apple ecosystem to check out the Secure Mobile Networking Lab of TU Darmstadt in general. They do a lot of cool stuff in the space, a good starting point might be https://owlink.org https://owlink.org. As a side note: I wonder what the story is on the whole AirTag hardware project. It's becoming so "delayed" that reverse engineered implementations are here before.
- nathanielostrer 6y agoCould you make this work with a tile?
- coolspot 6y agoThis requires BLE device to broadcast your public key in special packets. I don’t think you can upload custom logic on Tile to make it broadcast arbitrary BLE packets.
- londons_explore 6y agoYou could with a new firmware.
- KMnO4 6y agoNot really, but perhaps someone could make one based on a cheap Nordic NRF51823 or NRF5832. Actually, a quick search shows that you can already buy exactly that (even with Apple compatibility built in).
