So, this is proof of concept, not an actual attack at this time. Correct?
No, it's an actual attack. But we don't know for sure if it's being exploited actively in the wild. This vulnerability has existed ever since PCs adopted UEFI (~2006).
More importantly, does the attacker need physical access to the computer or can this be performed over the Internet/local network?
I'll answer because I found the information. It appears that the attacker would need to rely on physical access to the machine OR another exploit that lets them access the computer remotely.
So the best security is still keeping your computer behind a locked door and not clicking on suspicious stuff?
The best security is keeping it in box, removing the battery, and never turning it on. /j
Maybe I should hire an Amish guy as a consultant for IT. Those guys never get hacked.
Beg to disagree. See: “Amish Mafia.”
Or they could just get you to execute the command without your knowledge (eg: all the people who just blindly copy-paste commands, or pipe scripts from the net into
sudo). Or it could be a compromised github account/repo (supply-chain attack). Or even the ol' techsupport scam where they get gullible users to install stuff...
