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.
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...
