🔥 JS4Hacking Extension — Now as a Chrome Addon!

Demopic

I'm turning this wonderful set of tools into a full Chrome Extension — now it’s even easier to use.
No more messy data:, tricks or manual script pasting. Just toggle and hack.

📦 Import once — use forever.


🧠 What is JS4Hacking?

A collection of JavaScript tools tailored for bug bounty hunters, pentesters, and anyone digging deep into web apps.

Previously, you had to inject it manually or use TamperMonkey — now it lives in your browser toolbar, always ready to go.

So simply said, any webpage you visit, script tag is injected(then removed) to import list of functions.


🆕 What's New?

J4 Modules had upadte !!

What are J4 Modules

I was thinkng of something that during manual pentesting can help, without calling anything, and I came up with this idea, current Modules-pack is called Reflection Hunter

However in future I may add other features, and eventually create new Modules-pack


🛠️ How To Install (Manual)

  1. Go to chrome://extensions/
  2. Enable Developer Mode (top right)
  3. Click "Load Unpacked"
  4. Select your folder (e.g., ~/JS4hacking/)
  5. Boom! Now hit any target site, open DevTools(console), and use the extension!

🧩 Using the Extension

  • After importing all functions are auto injected in page
  • You can always write your own in Scripts/ and hook them in
