UPDATE
Based on @ws's comment and @nderscore's code, use this JSFiddle to decode the thing.
To find the password that this script asks for, you can use a simple debugging trick.
- Go to JSFuck and uncheck the
Eval Sourceoption. - Paste the obfuscated JavaScript
- Run
You'll see:
It seems to be calling prompt(), so put a breakpoint on it, like this:
(I'll be using Chrome for this)
- Open console (F12)
- Backup the original
promptlike this:window.prompt_ = window.prompt - Override the call to prompt with a breakpoint:
window.prompt = function(a, b){ debugger; return window.prompt_(a, b); } - Click
Run This - You'll break here:
- Check the callstack at the right bottom.
- Go back one function, and you'll see:
Bingo!
Password is forevermore:
