DanielGibson / theme-gitea-dark-colorblind.css

Colorbind-friendly dark and light themes for Forgejo (tested with 9.0.1)
/* DG: based on the compiled(!) theme-gitea-dark.css from Forgejo 9.0.1
* uses different colors for diffs so I can tell added/removed lines apart more easily
*
* I got the compiled file by opening Forgejo with selected gitea-light theme in Firefox,
* opening the "Web Developer Tools" selecting "Style Editor" tab,
* selecting "theme-gitea-light.css" from the list and Saving it.
* Could also edit it there in realtime and save the result.
*
* Then I copied the modified file (this file) to the Forgejo server to
* $FORGEJO_CUSTOM/public/assets/css/theme-gitea-dark-colorblind.css

ULTRA-SOPHISTICATED 0DAY APT SUPERMALWARE PROXY EXE

Inspired by our understanding of what CVE-2024-23940 does (see https://medium.com/@s1kr10s/av-when-a-friend-becomes-an-enemy-55f41aba42b1) HORST, the 1337est of hackers, infamous for having hacked THE DIALER back in 1998, has developed the next generation of that attack, and kindly gave me permission to demonstrate it here!

It turns out that you can't just write Proxy-DLLs that pass on function calls to original DLLs and also do evil things, but you can also create a Proxy Executable that calls the original exe and also does evil things!

Hacky Linux tool to explore Pulsar PCMK TKL Keyboard LED control (incl. documentation of that protocol)
/* Based on https://github.com/torvalds/linux/blob/master/samples/hidraw/hid-example.c
*
* This is for "0416:b23c Winbond Electronics Corp. PCMK TKL"
* USB VID 0x0416, PID 0xb23c, using a Winbond/Nuvoton Chip (NUC121SC2AE),
* sometimes also identified as Winbond "Gaming Keyboard",
* My actual device is a Pulsar PCMK TKL Barebone in ISO layout, but reportedly
* there are other devices with the same USB ID, like "KT108" or some from "WIANXP"
* that *might* use the same protocol, see also https://usb-ids.gowdy.us/read/UD/0416/b23c
