This prevents an attacker from ripping out your RAM and freezing it so they can pull secrets from it, which isn’t really an “exploit” per se. I’m sure they have other mitigations for those kinds of things. Or at least I hope they have something in mind, since they didn’t seem to be hiring for security currently…

Is there known instances of this attack? For me it sounds like Sci-Fi.

It's routine: https://en.wikipedia.org/wiki/Cold_boot_attack

I don't know how often forensics teams bother freezing the memory; it's not always necessary.

It's routine in the lab. If you can get into a CloudFlare cage there may be much more powerful attacks than stealing DIMMs.
