This is a terrifying exploit ("yes, absolutely"), but it is a one-time exploit that is not intended for sustained data xfer. It steals your initial cryptoseed (via SPI display linkage; no cryptographic exploit of ledger device is publicly-known, yet), and only has to broadcast one time from its literally-hand-wound antenna.

I believe one million+ devices are "suspected."

I'm just beginning to play around with Docker, and I have a spare eWaste Intel 4xxx (with dual PCI slots and two 56k modems!~); hoping that my own MacBook can "dock" in to my landline's RJ-11 "virtually" – that I can figure this out with LLMS as a dumbass electrician is incredible! – exciting stuff to learn'bout.

There was a prototype macbook pro on ebay from 20 years ago with a 3G modem in it, the retail MBP from the time even has the space for a SIM card near the battery door. Presumably they decided against it for a good reason.

They're not fully confident yet on the mmWave to go in the Macbook.

There's a reason they carefully have been bringing their own modem in via "weird" devices. The C1 came in on the 16e, C1X was the Air (phone+iPad), and they're finally confident enough to bring C2 to the mainline iPhones, but it seems like maybe not ready until C3 comes around next fall.
