    UEFI exploitation

    Hi, I'm the guy currently doing a bit of UEFI exploitation sometimes live on Twitch, archived on YouTube.
    I also created Fiedka, the firmware editor.

    Ask me anything! :-)

    there are many editors - most fall short, hopefully yours is better

      Sure!

      The editor is named Fiedka; see https://fiedka.app

      So far it supports parsing some UEFI, PSP and coreboot filesystems, removal of UEFI binaries and inserting LinuxBoot for a BdsDxe.
      I have used it successfully on a ThinkPad X270 to bootstrap LinuxBoot (i..e, a Linux kernel in flash) in combo with utk from the Fiano tool suite; see the PoC: https://mastodon.social/@CyReVolt/111683157133015896

      There are many shortcomings and tons of development still needs to be done. So, pull requests and issue are welcome!

      I occasionally do live streams at https://twitch.tv/cyrevolt and archive them at https://youtube.com/@cyrevolt

      Here is the firmware security playlist with UEFI stuff: https://www.youtube.com/playlist?lis...6c2vhd9V9GhCgF
      And another one on Fiedka, Fiano and LinuxBoot development: https://www.youtube.com/playlist?lis...ItEjylw5do4XxH

        Is unlocking UEFI worth the hassle? (Surface Pro 4)
        by CronaxFD
        Hey guys,

        Bought myself Surface Pro 4 tablet today on a local craigslist-type website.
        I've seen that UEFI was password protected and of course the seller forgot the password, but decided to buy it anyway.
        Really needed such a tablet to use with RomRaider to do some logging/tuning on my car.
        It has secure boot turned off and boots from USB, so I've formatted SSD and have done clean win10 install.

        Works fine, but wanted to ask, are there any real security risks associated with UEFI settings on Surface (remote access etc.)?

        From what I've...

        Intel NUC NUC6i3SYH UEFI Update went wrong
        by S70rm7r00p3r
        Hi guys.

        I am very new to this business and i have some questions. Maybe someone can help me further.

        I have a 2015 Intel NUC NUC6i3SYH and for some internet and office the computer works perfectly. Lately it has been bugging me a bit on and off. Then I saw there is a UEFI update from Intel and I thought if I put it on, the problems might be gone, but unfortunately the update didn't go through. The screen stayed black and after waiting for a while nothing happened, I had to pull the plug at some point. Of course, the NUC then failed to boot!

        Modify BIOS to non-uefi
        by hexdy
        Hello, I wanted to know if it is possible to modify a BIOS file to accept a legacy disk when it does not have the capability, I had this problem on a Optiplex 3060 that were donated to my job where we use non-uefi linux distros, we cannot use uefi since is a "big machine" with this systems beign the center of all of it, we can't change the distro now, maybe make some changes, but if I can modify the BIOS it would be awesome.
