Discover gists

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

List the network devices.

$ ls /sys/class/net

Edit the config file.

Goals

Can use Ubuntu Server 20.04 LTS to be Router Gateway include DHCP Server
Client who connected to Ubuntu Server can be access Internet

Environement

Ubuntu 20.04 LTS
2 Interface
- 1 Interface from WAN / ISP (enp2s0)
- 1 Interface for distribution clients (enx00e04c534458)

Good and fast integer hash

fn pcg(n: u32) -> u32 {
    var h = n * 747796405u + 2891336453u;
    h = ((h >> ((h >> 28u) + 4u)) ^ h) * 277803737u;
    return (h >> 22u) ^ h;
}

Most efficient way to bring all packages on your system up to the newes version. Use with

source("https://gist.githubusercontent.com/JBGruber/f751d414ced2374b9856451531c5997d/raw/yay.r")
yay()

Limitation

Only update CRAN packages due to the usage of old.packages(). Let me know if you have a better way to find outdated packages.

	To use a runningstats object,

	1. Create the the desired stat object, e.g., `m = Mean()`
	2. Feed it batches via the add method, e.g., `m.add(batch)`
	3. Repeat step 2 any number of times.
	4. Read out the statistic of interest, e.g., `m.mean()`

	Built-in runningstats objects include:

	#!/bin/bash

	# If not running via sudo, exit
	if [ "$EUID" -ne 0 ]; then
	echo "Please run as root"
	exit
	fi

	# quit if jq is not installed
	if ! command -v jq &>/dev/null; then
