The Poynting vector! I detect an EE or physics background.
And the technique is interesting in the abstract I guess, as in exploring it would make a cool master's thesis or, at a deeper level, a PhD dissertation. But it's not a realistic concern for anyone not a target of a very clever and determined government. After all, before the bad guy can exfiltrate data from the air-gapped system, he has to first get his malware onto the air-gapped system! And how many of us get anywhere near air-gapped systems anyway? Esp outside of a secure environment where only highly cleared people are allowed! _________________ 2x Netgear XR500 and 3x Linksys WRT1900ACSv2 on 53544: VLANs, VAPs, NAS, station mode, OpenVPN client (AirVPN), wireguard server (AirVPN port forward) and clients (AzireVPN, AirVPN, private), 3 DNSCrypt providers via VPN.
All rather interesting research, the practicality of real world scenarios dont factor into these conversations, I just enjoy reading these tidbits daily just to see what the cool kids come up with next.

Completely agree, it IS cool stuff!
And yes, perfect security requires a BIG rock. Or maybe a big one to live under and a medium-sized one to throw. So we practical types (some would deny my claim to that label) just try to make targeting us a big enough pain that automated systems for mass attack (or mass surveillance, for VPN fans) will simply miss us. Very few of us will ever be specific targets, and anyone in that category has bigger issues than IT security.
And it got me thinking, what if we just used all shielded cables?
I specifically use a WRT32x not because of its neat specs, But its also got shielded ethernet ports.
So the cable is completely shielded all the way from my computer to the router. And if your concerned about which motherboard I am using, Crosshair VIII.
Did not read about lantenna, but I am sure that shielded ethernet cables would be the way to go to mitigate it.
Anyway back on track, I do not think that this would be effective, but mostly on rare occasions when the attacker is very close to the computer.
I did a quick, and the keyword here is "quick", google search for shielded sata cables, but found mostly esata to sata cables. _________________ For people who are new to the dd-wrt forums >> http://www.catb.org/~esr/faqs/smart-questions.html#rtfm
