Haven’t done the research but I wonder if you can use this to piggyback with tiny arbitrary data data payloads.

- nik282000 2y agoYup, there was a project recently that used the airtag network to transmit data from a hardware keylogger. The computer could be totally gapped and the data still gets home via the typist's iPhone.
- xuki 2y agoIt's not airgapped if it has bluetooth access.
- roywiggins 2y agoPresumably you stick the bluetooth antenna in the physical keylogger.
- nissarup 2y agoSounds like a line from a conversation between a couple of pre-teen AIs.

- 3eb7988a1663 2y agoI am guessing this is the story: Keylogger leaks data via Apple AirTag network https://news.ycombinator.com/item?id=38126302 https://news.ycombinator.com/item?id=38126302
- LelouBil 2y agoI saw someone use this to track his mail state. They have a contact sensor inside their mailbox that rotates the broadcasted key based on the trigger count. If the key changed, aka a new different device is visible, you know mail has been dropped in, very clever !
- teruakohatu 2y agoThat is a fascinating project. Here is the link if anyone else is interested: https://hackaday.com/2022/05/30/check-your-mailbox-using-the-airtag-infrastructure/ https://hackaday.com/2022/05/30/check-your-mailbox-using-the... I wonder if the creator had neighbourhood style mailboxes down the road? If not this seems quite complicated solution for an object that is probably with range even BLE. I tried building a mail sensor a couple of years ago where the mailbox was a fair distance from where I was living. I was not able to create a solution that didn't either have false positives or false negatives. For an outdoor object jostled by wind and rain it is harder than it seems.
- miki123211 2y agoI wish we had more / more easily accessible networks that let you do this. Something that would let you send extremely tiny (<1kB) packets, using a wireless protocol that could be implemented extremely cheaply, piggybacking on the bandwidth of nearby internet-connected devices in a privacy-preserving way. Amazon has a network like this called Sidewalk, using Alexa devices as gateways, but I don't think it's very open to third-party experimentation, and it's definitely not an interoperable standard on the gateway side.
- amenghra 2y agoToo bad Fon didn’t work out, it could have been a global mesh network useful for this kind of thing.
- bhelkey 2y agoI don't particularly want my devices transmitting arbitrary packets from unknown parties.
- darknavi 2y agoStarlink's Swarm (or what ever they are calling it now) might be nice if they ever release the hardware and pricing.
- Tijdreiziger 2y agoHow about LoRaWAN?
