One idiotic idea I came up with a while back is to spin up a GPU load as a form of on-off keying, and use an SDR to grab the unencrypted signals from a wireless energy monitor to exfiltrate maybe 8 bits per minute.
He already did a similar one, though it relies on the attacker tapping directly into the power line because he couldn't come up with the wireless energy monitor idea. https://ieeexplore.ieee.org/document/8894040 …
It sounds like he's really, really bored.
It'll be amazing when he finds the printer!
The word soup in the abstract is amazing, as is the blatant "*Hammer" codename to get clicks via reference to RowHammer (which is orders of magnitude more of an accomplishment than anything this guy ever put out).pic.twitter.com/itL1tnOF7g
And skimming the paper, I don't think the guy even knows how his attack works. I think he thinks he's getting 20kHz of power consumption modulation to back-propagate through the SMPS. That's extremely unlikely. Much more likely it's just boring old EMI leaking backwards.
