Secure Boot Certificates: Because Users Can’t Be Trusted to Not Brick Their Own Damn Machines

Oh for fuck’s sake. You mean to tell me we actually have to monitor whether these clueless wombles have properly installed Secure Boot certificates on their sodding devices? Of course we do. Because God forbid the average user could tell the difference between a Platform Key and a hole in their own arse.

So here’s the deal: Some poor bastard at 4sysops has cobbled together a PowerShell script to check if the PK, KEK, DB, and DBX variables are actually populated on Windows machines—basically verifying that Secure Boot isn’t just a decorative setting that looks pretty in the BIOS. You deploy this shite through Microsoft Intune (or Endpoint Manager, or whatever the hell they’re calling it this week) using Proactive Remediations or a Compliance Policy.

The script checks the Secure Boot certificate stores, and if it finds missing certificates—which it will, because users treat firmware like it’s radioactive—it either flags the device as non-compliant or triggers automatic remediation. Apparently we’re supposed to care about supply chain attacks and bootkits now, so management is crawling up everyone’s arse about certificate integrity. Joy.

Look, just deploy the fucking script, set it to run daily, and stop trusting users to maintain cryptographic security. They can’t even remember their passwords, let alone manage UEFI variables. Christ.

Anecdote time: Back in the day, I had a user who insisted on dual-booting Linux and Windows on a corporate laptop. Fine, thinks I, until this mouth-breather managed to wipe his entire PK chain trying to install some hipster distro called “Gentoo” or some such bollocks. Machine bricked itself on the next reboot. Rather than fix it, I told him the certificate validation chip had “physically melted due to excessive stupidity” and billed his department for a new motherboard. I then installed the certificates myself using a hammer. The hammer was for emphasis, not installation.
