Leaking data via out of unconnected devices (both connected and unconnected) is a very interesting topic, often called “soft tempest”. Often this is the realm of absurdly costly lab equipment, source code isn’t published etc. Here i would like to demonstrate this using the simplest equipment and means, and make it very easy to reproduce.

This works by switching between 10Mbps and 100Mbps, which results in a change of the electromagnetic radiation that leaks from the devices. Switching to 100Mbps produces a signal at 125MHz, which is used to transmit morse code.
