🚨 There's a major attack going on via npm right now.

Do not install any packages right now.

Talk to your agent ASAP and check if you're vulnerable or have been compromised.

This is urgent ‼️

Instead of watching a 2-hour movie, watch this masterclass on Claude Code from scratch:

[Nav Toor @heynavtoor]

🚨 Someone compiled every "build it from scratch" tutorial on the internet into one place.

It's called build-your-own-x and it's the most starred repo in GitHub history.

466,000 stars. More than React. More than TensorFlow. More than any tool ever built.

And it's not code. It's a curated collection of step-by-step tutorials that teach you how to rebuild the technologies you use every day. From scratch.

Richard Feynman said: "What I cannot create, I do not understand."

That's the entire philosophy.

Here's what's inside:

→ Build your own Database from B+Trees to a full Redis clone
→ Build your own Docker containers in 500 lines of C
→ Build your own Git finally understand what a commit actually is
→ Build your own Neural Network not import tensorflow, real backpropagation from scratch
→ Build your own Operating System write a kernel in C
→ Build your own Programming Language interpreters, compilers, garbage collection
→ Build your own 3D Renderer ray tracing, pixel by pixel
→ Build your own Web Server, Web Browser, Search Engine, Shell, Regex Engine, Game, Blockchain, BitTorrent Client, Physics Engine, and more

Every category has multiple tutorials in multiple languages. C, C++, Python, Go, Rust, JavaScript, Java, Ruby, Haskell, TypeScript, and more.

Here's the part most people miss:

This isn't a beginner resource. This is the most advanced learning material that exists for software engineers. Because rebuilding something from scratch forces you to confront every design decision the original creators made.

You can't skip anything. You can't hide behind a library.

In the age of AI-generated code, this is the knowledge that becomes MORE valuable, not less. AI can import libraries. AI cannot replace an engineer who understands WHY systems work the way they do.

466K stars. 43.7K forks. Every tutorial is free. No paywalls. No sign-ups.

The best way to learn how something works is to build it yourself.

100% free. 100% Open Source.

🚨 Someone just open sourced a fully autonomous AI hacker and it's terrifying.

It's called Shannon.

Point it at your web app, and it doesn't just scan for vulnerabilities. It actually exploits them. Real injections. Real auth bypasses. Real database exfiltrations.

Not alerts. Not warnings. Actual working exploits with copy-paste proof-of-concepts.

Here's what this thing does autonomously:

→ Reads your entire source code to plan its attack
→ Maps every endpoint, API route, and auth mechanism
→ Runs Nmap, Subfinder, and WhatWeb for deep recon
→ Hunts for Injection, XSS, SSRF, and broken auth in parallel
→ Launches real browser-based exploits to prove each vulnerability
→ Generates a pentester-grade report with reproducible PoCs

Here's the wildest part:

It follows a strict "No Exploit, No Report" policy. If it can't actually break it, it doesn't report it. Zero false positives.

It pointed at OWASP Juice Shop and found 20+ critical vulnerabilities in a single run including complete auth bypass and full database exfiltration.

On the XBOW Benchmark (hint-free, source-aware), it scored 96.15%.

Your team ships code daily with Claude Code and Cursor. Your pentest happens once a year. That's 364 days of shipping blind.

Shannon closes that gap. One command. Fully autonomous.

The Red Team to your vibe-coding Blue team. Every Claude coder deserves their Shannon.

10.6K GitHub stars. 1.3K forks. Already trending.

100% Open Source. AGPL-3.0 License.
