[ot][random][spam] Beyond HertzBleed: Reverse Engineering the Butterfly Effect

[Undiscussed Horrific Abuse, One Victim of Many]

just making a topic for this for completeness, not seeing much the
value of exploring it in depth atm

basically hertzbleed shows how a subtle influence from code details
can be used, with accumulated and chosen data, to reconstruct
information at a distance.

there's a lot more influence from things than a cpu's frequency
scaling. a _lot_ . and this stuff is happening now with transformer
models: picking up what things are based on complex data with degrees
of removal from the information in question. could clearly be used to
crack cryptography, but it seems other things are building.
