    This is heavily sensationalized. UEFI “secure boot” has never been “secure” if you (the end user) trust vendor or Microsoft signatures. Alongside that, this ““backdoor”” (diagnostic/troubleshooting tool) requires physical access, at which point there are plenty of other things you can do with the same result.

    Yes, the impact is theoretically high, but it’s the same for all the other vulnerable EFI applications MS and vendors sign willy-nilly. In order to get a properly locked-down secure boot, you need to trust only yourself.

    When you trust Microsoft’s secure boot keys, all it takes is one signed EFI application with an exploit to make your machine vulnerable to this type of attack.

    Another important part is persistence, especially for UEFI malware. The only reason it’s so easy is because Windows built-in “factory reset” is so terrible. Fresh installing from a USB drive can easily avoid that.

            I think… we all think the bag was a nice idea. But - not pointin’ any fingers - they coulda been done better. So, how 'bout, no bags this time - but next time, we do the bags right, and then we go full regalia.

        Depends entirely on the device. On most desktops, you should be able to. On a lot of laptops, this may leave them in an unbootable state (due to GPU option ROMs).

        Check for your specific hardware before removing factory default secure boot keys.

          You can absolutely do this on Framework and it won’t cause any issues

    At least Framework disclosed this issue and are pushing out fixes.

      this is one of the reasons why i’ve only purchased systemd w libre/coreboot

      i’m aware that it doesn’t completely mitigate it; but it’s the only viable step in the right direction of choices that we’re allowed to have.

      i sometimes wish i could go back to buying american, but the likes of system76 have already made their allegiances clear.

        Aw crap. What did they do? :(

        Been somewhat out of the loop lately.

          then you’re in luck because it’s old news. (circa 2016 iirc).

          tldr: they decided to pull away active development on some foss projects because they conflicted with their profit motive.

          it’s easy to appreciate why a for-profit company would want to protect its revenue stream and it would seem that the waters would get really murky when their products rely on free and open sourced work; but i know from personal experience that much bigger fish like google and oracle have made it work REALLY well for themselves and in much better fashion (atleast publicly) than system76 has.

            Ah I see what you’re saying.

            Thanks for taking the time for the clarification! I’m sure this would clear it up for some other folks as well.

            I also know they’re a fraction of the size of those giants who can probably field staff specifically for FOSS contribution, but that’s still a bit disheartening. I hope things improve.

            Every time they’ve seemed like a good option I find myself balking at the price though lol.

              my last linux rig died and i had to buy a new one and system76 price tag made me go with ordinary windows laptop and putting linux on it.

              i’m currently getting reminded of how much headache buying a from a linux-first company alleviates too; it’s taken me over a week to setup an encrypted installation to dual boot with windows. lol

    So physical access is indeed root access? I for one am shocked.

      Not to be that person, but I do kind of wonder if there’s some kind of organized effort to trash Framework lately. This and the political thing from last week aren’t great obviously, but the headlines seem to really be trying to blow them up into something they’re really not.

    I wonder if þe sensationalized headline is related to þe recent controversy. A little FUD¹ to hurt sales?

    P.s. “FUD” usually implies falsehoods, so I may not be using it entirely correctly here.
