amazing how much shittier it is to be in the rat community now that the racists won. before at least they were kinda coy about it and pretended to still have remotely good values instead of it all being yarvinslop.

it would be nice to be able to ever invite rat friends to anything but half the time when I’ve done this in the last year they try selling people they just met on scientific racism!

    i guess it only makes sense that rats get wowed by TEMPEST if they all self-taught physics

    ignore for five minutes that it’s one way only, someone has to listen for it specifically, 2.4GHz is way too high frequency to synthetize this way, and in real life it gets defeated by such sophisticated countermeasures like “putting a bunch of computers close together” or “not letting adversary closer than 50m” because it turns out that real DCs are, in fact, noisy enough to not need jammers for this purpose

      reminded of mordechai guri (from ben-gurion uni) whose whole dept just keeps popping out side channel attacks year after year, but most of them are in “the coil sits in the plate under the bagel (also ignore the PCB for data decode)” field of capacity (exactly because of noise etc)

      I mean, some legitimately interesting research on its own in this field - the stuff about cpu states through power sidechannel (most desktop/laptop PSUs are non-filtering and not isolated, so you can reverse-observe cpu state from minute differences on supply side) and such are pretty neat! impractical as fuck, but neat

        i didn’t knew who exactly does that, but this is entire genre of paper that’s not very useful in practical terms even if it might be slightly interesting. “we found an attack that breaks airgapping!” looks inside: requires compromise in advance. the one i had in mind was about using currents from gpu power supply lines that turns out radiate, depending on power states, and cycling these rapidly allows to exfiltrate information

          yeah, very similar profile to this lot (might’ve even had them involved). this seems to be collection of their stuff (I dunno if it’s complete, probably all the stuff they wanna show off)
