hi, i'm daniel. i'm a 15-year-old high school junior. in my free time, i hack billion dollar companies and build cool stuff.

3 months ago, I discovered a unique 0-click deanonymization attack that allows an attacker to grab the location of any target within a 250 mile radius. With a vulnerable app installed on a target's phone (or as a background application on their laptop), an attacker can send a malicious payload and deanonymize you within seconds--and you wouldn't even know.

I'm publishing this writeup and research as a warning, especially for journalists, activists, and hackers, about this type of undetectable attack. Hundreds of applications are vulnerable, including some of the most popular apps in the world: Signal, Discord, Twitter/X, and others. Here's how it works:

Cloudflare

By the numbers, Cloudflare is easily the most popular CDN on the market. It beats out competitors such as Sucuri, Amazon CloudFront, Akamai, and Fastly. In 2019, a major Cloudflare outage k

Proxmox LXC ⇆ CIFS Mount Wizard

proxmox-lxc-cifs-share.sh is an interactive helper that mounts a network CIFS/SMB share on a Proxmox VE node and bind-mounts it into one or more unprivileged LXC containers in one pass.
It automates:

1. Creating a host-side mountpoint under /mnt/lxc_shares/<folder>.
2. Writing a properly-tuned /etc/fstab entry (systemd.automount, uid/gid mapping, etc.).
3. Mounting the share immediately.
4. Injecting the bind-mount (mpX:) into the live LXC configuration with pct set.
5. Stopping and restarting each container to apply the mount.

Here are the steps I took to upgrade my nodes when the time came. Make sure that your apt upgrade and apt dist-upgrade don't have any errors.

Additionally, on one of my nodes, I had to confirm the grub install location. So It may be good to do this prior to upgrading by confirming the mount point of your boot disk.

apt remove --purge r8168-dkms -y
rm /etc/modprobe.d/blacklist-r8169.conf
sudo sed -i 's/GRUB_CMDLINE_LINUX="r8168.aspm=0 r8168.eee_enable=0 pcie_aspm=off loglevel=3"/GRUB_CMDLINE_LINUX=""/' /etc/default/grub

How to automatically mount a network Samba share on Arch Linux!

1. Install the [cifs-utils][1] package: sudo pacman –S cifs-utils.
2. Make a mount folder for the SMB share: sudo mkdir /mnt/<Path>.
3. Create a backup of the [fstab][2] file (just in case): sudo cp /etc/fstab /etc/fstab_backup.
4. Open the [fstab][2] file in your favorite editor: sudo vim /etc/fstab.
5. Add the mount line: //<Server_address>/<Server_share_and_internal_path> /mnt/<Path> cifs username=<Server_user>,pass=<Server_password> 0 0.

6. Save the file.
7. Reload [fstab][2]: sudo mount -av.

Wireguard and iptables restrictions for multiple users

If you don't know what Wireguard is, well, you should. It's fast, easy to setup and highly configurable. We will configure Wireguard for multiple users with various restrictions using iptables.

Assumptions

This should fit most setups (not mine though 😉)

Installing Arch Linux with Full Disk Encryption

If you're aiming for a seamless Arch Linux installation in UEFI mode, follow along as this guide will walk you through the process step by step. We'll be using LUKS (Linux Unified Key Setup) and LVM (Logical Volume Manager) partitions on LUKS to achieve full disk encryption.

Note: I have updated this doc for UEFI mode. For those with BIOS/MBR systems, you can refer to the previous version, but keep in mind that it might be outdated and no longer accurate.

If you're only interested in installing Linux and not setting up dual boot with Windows, feel free to skip the Windows-related sections.
