“Whether a proof of concept or not, Bootkitty marks an interesting move forward in the UEFI threat landscape, breaking the belief about modern UEFI bootkits being Windows-exclusive threats,” ESET researchers wrote. “Even though the current version from VirusTotal does not, at the moment, represent a real threat to the majority of Linux systems, it emphasizes the necessity of being prepared for potential future threats.”

How many distros support secure boot out of the box? IIRC it’s only Ubuntu and RHEL. The rest require hacking some shit together with self signed keys.

Don't know, been rolling with Gentoo for some time now.

I wouldn't trust "out of the box" support anyway as that would imply trusting microsoft keys.

It is so annoying that one can't ditch m$ keys and still boot windows. Sure you can sign the windows bootloader with your own keys. However it checks its own signature and just refuses to boot.

If anyone has a solution let me know.

I checked my store and there are Canonical keys there, but I don’t think that’s on every computer.
