    Phoronix: Intel Releases Linux-Compatible Tool For Confirming ME Vulnerabilities

    Intel's SA-00086 Detection Tool has Linux support and will confirm whether your system is vulnerable to the recently published Management Engine (ME) security issues...

    Intel ME is wrong in so many ways. It just needs to vanish completely.

        If you have a motherboard on this list, dual BIOS or a programmer capable of flashing BIOS EPROM chip then you can use me_cleaner to remove most of the intel ME code from your system:

        https://github.com/corna/me_cleaner (download bios, strip ME, flash bios). Vast majority of recent kernels do have no problems running without ME, but there is nonzero risk of bricking your motherboard (check issue #3 for success stories and tested boards).

          It took me 2 seconds to understand that you tested the Intel tool on a Ryzen system, nice one hahaha

            Christ on a bike. Do you know who my system manufacturer is? It's ME. Some of us know how to plug things into the sockets where they fit and then install an OS, it isn't that difficult (connecting the case wires to the mobo can be a bit fiddly, but hey).

            What's involved in sorting this out for those of us who don't get our stuff from Dell? Is it like a BIOS/UEFI update or something? Or is there an update you can run when you're actually booted into the OS?

            This is crap, the little I know about Intel ME is that it is very low level, how do they justify writing crappy code like this that's so difficult to diagnose and patch?

            Maybe they should have coded this stuff in Rust

              And how do we know that there is not another backdoor in this tool?

                  Yes, it's the motherboard manufacturer.

                  It's ME. Some of us know how to plug things into the sockets where they fit and then install an OS, it isn't that difficult (connecting the case wires to the mobo can be a bit fiddly, but hey).
                  This does not make you a "manufacturer" any more than a guy in a Ford assembly line is "manufacturing" cars.
                  You are just doing the dumb and menial job of connecting standardized components.

                  What's involved in sorting this out for those of us who don't get our stuff from Dell? Is it like a BIOS/UEFI update or something? Or is there an update you can run when you're actually booted into the OS?
                  It's a UEFI update and comes from your own board manufacturer.

                  Or, if you want to take the situation in your own hands you can buy a hardware flasher (to read/write manually the UEFI chip) and try the "me_cleaner" tool linked above that neutralizes the ME.

                  (the hardware flasher + another PC allows you to reflash back the original UEFI firmware in case something goes bad, among other things)

                  This is crap, the little I know about Intel ME is that it is very low level, how do they justify writing crappy code like this that's so difficult to diagnose and patch?
                  It allows their businness customers to maintain control over PCs and motherboards they sell to the end users, and they probably pay for the privilege.

                    Nice to see me_cleaner works

                    I used the cleaner on a Kaby Lake laptop; here's my report for anyone interested: https://github.com/corna/me_cleaner/...ment-343714315
