I wrote a bit about hunting for UEFI Implants, and realising that we’re failing as an industry -- along with some ideas of things we could do to fix it. Comments welcome, especially from

I am glad to announce that we released the source code of KARONTE at https://github.com/ucsb-seclab/karonte …. Our tool tracks information data-flow across the different components of a firmware and finds vulnerabilities. Our paper can be found at http://www.badnack.it/static/papers/University/karonte.pdf …

Infosec people: Are there any viable attacks on the FS8806 I2C/SPI software authentication chip or its associated "Concerto" embedded library? I'm not looking to pirate software per se, but it was used on the "Happy Fish" bootleg MAME board, and is a real gnarly S.O.B.

I made an experimental x86 bootloader using
@rustlang for BIOS boot. This program can boot the ELF formatted kernel which compressed with bzip2. it decompresses the bz2 image and relocate the ELF image, then boot the kernel.#rustlang#bootloader#osdevhttps://github.com/ellbrid/krabsHvala.

It has come to our attention that several Battlefield 5 players have recently been banned for playing on Linux, and that EA has chosen not to revert these wrongful punishments. Due to this, we advise to refrain from playing any multiplayer games published by
@EA in the future.Prikaži ovu nitHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -

New blogpost: Sanitized Emulation with QEMU-AddressSanitizer https://andreafioraldi.github.io/articles/2019/12/20/sanitized-emulation-with-qasan.html … I just open-sourced my QEMU patches to fuzz binaries with ASan, QASan. You can also use it with ARM targets on Linux, a thing that you can't do with LLVM ASan!

Side-note for professors & teachers: I made it a requirement for students to cite any URL as an
@internetarchive'd URL—meaning students had to archive before citing. This class alone created hundreds of archived sources, including obscure posts and whatnot. You should too.Prikaži ovu nitHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -
