Could you be more specific? What kind of obfusication did they use...? Can we see the obfusication?

I'm no expert on lua bytecode however if you just take out all the "\0" and then print it you can get a basic idea of what the code is. For example, I can tell that code there is something like

    function name()
        return function
            print("Hello World!")
        end
    end
    
    print'Hello World!'

No I mean put the obfusicated script without \0's in it into a print() function and it will tell you the code.

After printing it, you run the script right?
