Etherify – bringing the ether back to ethernet – SQ5BPF notes (Link)

Two methods for generating RF signals using ethernet, allowing exfiltration of data from air-gapped devices. This is implemented for the demo by sending a message in Morse code.

The first method involves swithing ethernet speed between 10 and 100, which generate signals at 10 and 100 MHz. The second involves sending data a 1Gbps, which generates a controllable change in frequency at 125MHz, perhaps due to hardware idiosyncrasies.
