That is not an air gapped wallet then and therefore beyond the scope of the discussion at hand.
In fact, I don't even know if there are air gapped wallets on the market.
There are some that claim to be air gapped but then use QR codes to transfer data. Which makes them not air gapped at all. A QR code displayed on one device and scanned on another is no less a communication channel than a cable. If it has a malicious helper software on the computer, the wallet could transfer your seed phrase over the image just fine. But that is a different attack vector than the one discussed here.
The discussion here is about whether an actually air gapped wallet could phone home or not. Independent of the question if one exists.
- paulryanrogers 4y agoI thought air gapped meant no automated communication channel. After all a human interacting with an AG machine could memorize some of its data then reenter that data elsewhere. Isn't a QR code passing through an analog medium, and only when read manually? It's also one way: from the wallet to the external reader. Unless I'm misunderstanding something.
