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! :-)

post some channel links and a link to the editor
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

Its a bit of a long tale but i swapped the original hd for a 2tb ssd,i want about 6 bootable partitions,it needs the uefi enabling in the bios,I am ok with that,the issue is i cant convert the drive to gpt when it has data on it,the issue is windows wont install to a gpt drive,there is a utility from hp to install the efi partition on the drive but it runs on windows,its a chicken and egg thing,can anyone explaine how hp did this?,I am pulling my hair out;it seems i need to run the hp uefi tool to make the uefi option work in the bios, but it needs windows to run this that wont install on a gpt...07-15-2024, 10:15 AM -
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... -
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!

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. -
Not a BIOS request per se, but closely related. Please bear with me
A while ago I found an old Lenovo Thinkcentre M720q in pieces in the electronics scrap bin at work. There was only some minor damage to the case, so collected everything and brought it home to let it dry and see if it still worked. It did
Unfortunately Computrace has been activated on it. Since I'm using it as an emulation console with Lakka now, it's no big deal, but would be nice to get rid of the annoying message popping up when entering the UEFI setup, and also learn something along the way....
