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

Fixing device UUIDs in BCD under Linux

Please note, it's easier to just use a recovery flash drive/dvd disk!

I just wanted a new challenge, and I found it:

Info on target system

My friend has switched from Windows to Fedora. Somehow in the process, Windows Bootloader went missing from EFI partition (I would love to know how did that happen as much as you do or don't, but I wasn't supervising at the moment, so... no idea)

How to build Mesa Turnip with `-Dplatforms=android` but without cross-compilation

Small warning: This will "mess up" your Termux installation's zlib.pc file, but if you do other compilations with really similar settings to this one, you're probably going to need it again before you "fix" it by reinstalling Termux's official zlib anyway.

Install Termux

termux-setup-storage
pkg install git make clang binutils
git clone https://github.com/madler/zlib.git

Minimal D3D11 sprite renderer

Minimal D3D11 sprite renderer: basic back-to-front sprite rendering reference code with example sprite sheet animation logic. As usual: Complete, runnable single-function app. No modern C++ / OOP / obscuring cruft.

Swap out the sprite sheet with a font atlas for a lightweight GUI / text renderer. Clip individual sprites and glyphs by offsetting screenPos and atlasPos to top left corner of visible area and adjusting size accordingly (all values in pixels):

sprite.screenPos.x += 17;
sprite.screenPos.y += 10;

Using TypeScript Node.js with native ESM

This reference guide shows how to configure a TypeScript Node.js project to work and compile to to native ESM.

Rationale

CommonJS module system was introduced by the Node.js developers due to the lack of the notion of "modules" in the original JavaScript (ECMAScript) language specification at that time. However, nowadays, ECMAScript has a standard module system called ESM — ECMAScript Modules, which is a part of the accepted standard. This way CommonJS could be considered vendor-specific and obsolete/legacy. Hopefully, TypeScript ecosystem now supports the "new" standard.

So the key benefits are:

This downloads standalone MSVC compiler, linker & other tools, also headers/libraries from Windows SDK into portable folder, without installing Visual Studio. Has bare minimum components - no UWP/Store/WindowsRT stuff, just files & tools for native desktop app development.

Run py.exe portable-msvc.py and it will download output into msvc folder. By default it will download latest available MSVC & Windows SDK - currently v14.40.33807 and v10.0.26100.0.

You can list available versions with py.exe portable-msvc.py --show-versions and then pass versions you want with --msvc-version and --sdk-version arguments.

To use cl.exe/link.exe first run setup_TARGET.bat - after that PATH/INCLUDE/LIB env variables will be updated to use all the tools as usual. You can also use clang-cl.exe with these includes & libraries.

To use clang-cl.exe without running setup.bat, pass extra /winsysroot msvc argument (msvc is folder name where output is stored).
