#StackBounty: #ubuntu #bios #uefi #hp Investigating HP sure start triggering security warnings

Bounty: 100

The following question belongs more to the HP forums but unfortunately I am not gaining any traction there. Please move the question to another SE if its off topic for this community.

Recently I’ve started receiving the following BIOS interruption & message at each boot:

"HP Sure Start detected an unauthorized change to the Secure Boot
Keys. The key was restored automatically and there is no further
action required. The repeated occurrence of this problem indicates a
security problem should not be ignored."

See screenshot at the bottom.

I have no idea what is causing this warning. I recall recently updating Zoom and perhaps a routine Ubuntu update, but nothing else.

I am using the laptop for security critical interactions so I want to make sure I understand what is causing this and how to get to the bottom of it.

Any idea how I could investigate what is changing Secure Boot keys and why? What exactly could be the trigger for such warning? How can this be investigated further and resolved?

I am running Ubuntu 20.04.1 LTS.
