hi, i'm daniel. i'm a 15-year-old with some programming experience and i do a little bug hunting in my free time. here's the insane story of how I found a single bug that affected over half of all Fortune 500 companies:

say hello to zendesk

If you've spent some time online, you’ve probably come across Zendesk.

Zendesk is a customer service tool used by some of the world’s top companies. It’s easy to set up: you link it to your company’s support email (like [email protected]), and Zendesk starts managing incoming emails and creating tickets. You can handle these tickets yourself or have a support team do it for you. Zendesk is a billion-dollar company, trusted by big names like Cloudflare.

Personally, I’ve always found it surprising that these massive companies, worth billions, rely on third-party tools like Zendesk instead of building their own in-house ticketing systems.

your weakest link

This is from man bash:

A pipeline is a sequence of one or more commands separated by one of the control operators | or |&. The format for a pipeline is:

[ time [ -p ]] [ ! ] command [ [ | | |& ] command2 ... ]

This is the only place in which ! can appear. It never prefixes commands, it prefixes pipelines.

A Short IPv6 Guide for Home IPv4 Admins

This guide is for homelab admins who understand IPv4s well but find setting up IPv6 hard or annoying because things work differently. In some ways, managing an IPv6 network can be simpler than IPv4, one just needs to learn some new concepts and discard some old ones.

Let’s begin.

First of all, there are some concepts that one must unlearn from ipv4:

Concept 1

First of all, uninstall the `eos-hooks` package, which keeps changing the data of `/etc/os-release` from a hook while installing base packages.

sudo pacman -R eos-hooks

Reinstall the `base` package group:

sudo pacman -Syyu --noconfirm archlinux-keyring bash bzip2 lsb-release coreutils file filesystem findutils gawk gcc-libs gettext glibc grep gzip iproute2 iputils licenses pacman pciutils procps-ng psmisc sed shadow systemd systemd-sysvcompat tar util-linux xz linux

	90-70% of Bloodlight lore is collected here.

	Information taken from the author's X.com (https://x.com/00_Homura), PillowFort (https://www.pillowfort.social/02_Homura) and RetroSpring (https://retrospring.net/@H0mura).

	Most information is provided in Q/A format without user names or separations. The only separations are my "map legend" and an empty paragraph between pieces of lore.

	Also, some information is provided simply in the form of copied text under the author’s posts.

	The main focus was on the world setting and Mother Almonde. So there is either no information on some characters at all, or just a little bit.

	There appears to be a string encoded in the binary payload:

	Which functions as a killswitch:

	Thus, one workaround for affected systems might be to add this to `/etc/environment`:

	```

	#!/usr/bin/env bash
	# Likely only works on Linux due to GNU Find, probably needs to be ported for BSD utils

	OPTIONAL_FIND_ARGS=-xdev # Remove if you don't have slow remote mounts etc.

	# Start with liblzma
	LIBS=liblzma.so.5

	LIB_DIRS="/usr/lib /lib"
	BIN_DIRS="/usr/bin /bin /usr/local/bin"
