On: PowerHammer: Exfiltrating Data from Air-Gapped Com...

It’s likely that whomever exploits this would do both easier way and this way.

This one is particularly great because an air gap is assumed by default to be very secure.

So you may think things are fine and dandy cause you gotta fancy lil air gap but lo and behold your data has been exfiltrated through the power lines for years.

NSA has very strict power filtering rules for their Red/Black systems. Their building is covered in a copper Faraday cage.

They also have a double outer shell, with space between the two walls, where speakers play white noise.

All this is public knowledge for many decades now.

Food for thought.

If anyone is surprised by power line exfiltration they just didn't do a basic google search.

Or still thinks that computers are magic or that electricity is binary (either on or off).
