I'm aware of "Find My Device" that's a documented feature. Find My beacons go OUT (your device tells others where it is). This is 84MB coming IN. Different thing.

Well, such traffic goes OUT somewhere and that somewhere is other iDevices so that's traffic coming IN for them, no? I don't have evidence supporting either possibility other than the fact that there's indeed an obscure mesh network involved for "Find My" to operate. I hope this is the starting point to figuring out what their infrastructure does.

The repo shows traffic is bound to utun2 (IDSNexusAgent). That’s not a location beacon protocol… that’s an encrypted IP tunnel
