No, this is not true at all. Microsoft requires their system vendors (Dell, HP, etc) to allow users to enroll their own Secure Boot keys through their “Designed for Windows” certification.

Further, many distributions are already compatible with Secure Boot and work out of the box. Whether or not giving Microsoft the UEFI root of trust was a good idea is questionable, but what they DO have is a long, established history of supporting Linux secure boot. They sign a UEFI shim that allows distributions to sign their kernels with their own, distribution-controlled keys in a way that just works on 99% of PCs.

Well, this project is literally about me circumventing/removing Boot Guard so I don’t know how it’s corporate authoritarianism. I’m literally getting rid of it. In doing so I get complete control of the BIOS/firmware down to the reset vector. I can disable ME. To me, that’s ultimate freedom.

As a power user, do I want boot guard on my personal PC? Honestly, no. And we’re in luck because a huge amount of consumer motherboards have a Boot Guard profile so insecure it’s basically disabled. But do I want our laptops at work to have it, or the server I have at a colocation facility to have it? Yes I do. Because I don’t want my server to have a bootkit installed by someone with an SPI flasher. I don’t want my HR rep getting hidden, persistent malware because they ran an exe disguised as a pdf. It’s valuable in some contexts.

Yeah, but that doesn’t give me a reason to use the hot air station and hot plate collecting dust on my desk ;)

I have a slow burn project where I simulate a supply chain attack on my own motherboard. You can source (now relatively old) Intel PCH chips off Aliexpress that are “unfused” and lack certain security features like Boot Guard (simplified explanation). I bought one of these chips and I intend to desolder the factory one on my motherboard and replace it with the Aliexpress one. This requires somewhat difficult BGA reflow but I have all the tools to do this.

I want to make a persistent implant/malware that survives OS reinstalls. You can also disable Intel (CS)ME and potentially use Coreboot as well, but I don’t want to deal with porting Coreboot to a new platform. I’m more interested in demonstrating how important hardware root of trust is.
