> By forcing one of the three variables of DVFS (heat, power, or frequency) to become a constant, the researchers can then monitor the other two variables to distinguish which instructions are being executed, even with enough precision to ascertain the different operands of the same instruction.
Sounds like one of those attacks that works in theory but is too impractical to use in real life. This is harder than cache side channel attacks, and we still haven’t seen much use of those in the wild, years later.
> Ultimately, this furthers other attacks, like website fingerprinting.
Umm no. Did ChatGPT write that? Fingerprinting isn’t an attack and that’s not how it works. Also this requires access to system temperatures and other metrics that are absolutely not available from JavaScript.
