In this age of NFC, WiFi, BT, RFID, and everything in between, I am really not sure that the elite security concept of “air-gapping” is even meaningful or useful anymore.
Just because a measure is less useful doesn't mean it is useless.
There is always a compromise between convince and security and in this case one would have to do even more screening (less convince) for the same security level. Even if airgaps like before increases effort needed for exfiltration.
Very interesting. What's the max payload size we can transfer with this setup?
This looks like a custom Airtag which is great — but I cannot find where it exfiltrates data from an air-gapped system.
What did I overlook?
Looking at the code, looks like it advertises under a different private key for each bit in each message.
