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

Pure ESM package

Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

  1. Use ESM yourself. (preferred)
    Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
  2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
  3. Stay on the existing version of the package until you can move to ESM.

HTML Tags You Can Use on GitHub

HTML Tags You Can Use on GitHub

Wherever HTML is rendered on GitHub (gists, README files in repos, comments on issues and pull requests, ...) you can use any of the HTML elements that GitHub Flavored Markdown (GFM) provides syntactic sugar for. You can either use the syntactic sugar that GFM (or other GitHub-supported markup language you're using) provides or, since Markdown can contain raw HTML, you can enter the HTML tags manually.

But GitHub also allows you to use a few HTML elements beyond what Markdown provides by entering the tags manually, and some of them are styled with CSS. Most raw HTML tags get stripped before rendering the HTML. Those tags that can be generated by GFM syntactic sugar, plus a few more, are whitelisted. These aren't documented anywhere that I can find. Here's what I've discovered so far:
