Unique 0-click deanonymization attack targeting Signal, Discord and hundreds of platform

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

Building a uWSGI Emperor for multiple python versisons
September 5, 2015
This is a quick update to my tutorial on hosting Django Apps on Ubuntu with Nginx and uWSGI. I recently wanted to move to a mix of Python 3.4 and Python 2.7 web apps on one of my servers that was set up as described in that tutorial. Here's how to do that.
Normally, I just install uWSGI using pip. The big downside of that approach is that it only builds uWSGI for the version of Python with which you install it. So to get one emperor that can run apps (vassals) with different versions of Python, we need to compile uWSGI. Luckily it's really easy.
Here is an example of the required steps. Just run the following commands as root.
