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

organize images using AI

Organize Images into folders using AI

This is a tool that sorts images into folders using "AI". You create the folders you want the images to be put into.

I got 'claude' to write with a couple prompts. Make venv and install deps with pip.

Signed Distance Field generator for Unity with Burst support
/*
Based on the Anti-aliased Euclidean distance transform described by Stefan Gustavson and
Robin Strand. For further information, see https://contourtextures.wikidot.com/ and
https://web.archive.org/web/20220503051209/https://weber.itn.liu.se/~stegu/edtaa/
The algorithm is an adapted version of Stefan Gustavson's code, it inherits the copyright
statement below, which applies to this file only.
The rewrite with Unity Burst support makes the execution 40 times faster by default,
and 75 times faster if the passed in textures are both of type TextureFormat.RGBAFloat.

You Can Gaslight Yourself Into Loving Someone

You Can Gaslight Yourself Into Loving Someone

Ever thought about how Love (or having a crush) is like having an addiction to a person? Well, it is and you can benefit from knowing this. Ever gotten to know someone slowly and realised after a while that even though they seemed almost-perfect (kind, outgoing, cute, smart, introspective, and understanding) you still didn't have any feelings for them? No? Just me? OK, but it can happen to you! Read on.

Disclaimer: I'm not a psychiatrist, nor am I a doctor or have any medical background or really any authority to talk about any of this. I'm a programmer and I didn't even finish my masters. I might be autistic but haven't been diagnosed (assessment soon!) so for now I'm just a Weird Nerd who writes about complexity aaaaaand let's move on to the interesting stuff.
