Haven’t we been here before? It seems like it’s very similar to the branch prediction exploits of the late 2010s. Is there something particularly novel about this class of exploits?

Probably, I haven't had time to delve into the article yet. But ever I first learned about them I got the hunch that they'd never fully go away.

Then people say "no that's not possible, we got security in place."

So then the researchers showcase a new demo where they use their existing knowledge with the same issue (i.e. scaling-induced voltage leaks).

I suspect this will go on and on for decades to come.

It's the same exploit, just exploiting a bug in the mitigation for the first exploit.
Predictable suite.^_^ Disable the feature in BIOS if possible. Branch prediction is a rotten plank that needs to be scrapped. It's a remarkably bad idea that doesn't deserve to be saved.
