Are there any tricks or guides out there to protect from this attack? Obviously not leaving hardware running and unattended, but what else can help protect you if your running laptop is stolen out of your hands? Workstations can be configured to shutdown upon intrusion switch being activated but what about laptops? I guess hot gluing the RAM in would be a physical obstacle. What about a BIOS password being required for booting from external media or having secure boot enabled? There are exploits to bypass those things, but to an attacker not finding out they are up against that until they reboot, I would hope that would slow them down enough that they fail. If half of or all of the RAM is mounted under the keyboard, I think they would have difficulty getting it out in time. Besides spraying the RAM directly, can you freeze an entire laptop while it's still running? Won't condensation cause problems pretty quickly?

Could you elaborate on this? What device did you test on, what was the test procedure, and what was the outcome?

Does it stop EFI from running first? I'd think that EFI would be clobbering a whole lot of RAM.

Haters, please stop flagging liffik's comments. I know you don't like AI but this thread was legitimately upvoted onto the front page so at least let the author respond to people.
