Date: Fri, 6 Nov 2020 18:49:34 +0100 (CET) From: Jacek Lipkowski <fdlist@...kowski.org> To: fulldisclosure@...lists.org Subject: [FD] Etherify - bringing the ether back to ethernet Hello I've published a short description how to transmit radio signals using the ethernet interface, for example by changing the interface speed, or by loading the interface with packets. The implementation is deliberately very primitive (shell scripts, uses native system tools). The data is transmitted via morse code, so that one can judge the signal/noise ratio be ear, and decode by ear (which is much better. an average human operator easily outperforms all software i've tried). description: https://lipkowski.com/etherify demo: https://youtu.be/ueC4SLPrtNg scripts: https://github.com/sq5bpf/etherify This isn't 100% related to security but some of you might find this hack amusing. It could be used to leak some data from a system which is not connected to a public network via electromagnetic emanations or as a tempest demo. Have fun :) Jacek / SQ5BPF _______________________________________________ Sent through the Full Disclosure mailing list https://nmap.org/mailman/listinfo/fulldisclosure Web Archives & RSS: http://seclists.org/fulldisclosure/
