Hi devs, does anyone know how to deobfucate a lua script made with moonsec?

i have NO idea what language you just spoke so i looked it up and here you go

How can I deobfuscate MoonSec V3?

Yes, I know that there are already multiple posts discussing this topic. None of them led to any real results. I want a straight answer. How do I deobfuscate MoonSecV3?

A bit of background

Basically, I’ve found a few exploiting scripts, and I want to dissect them for learning purposes. At the top of every single script is This file was protected with MoonSec V3 , followed by… gibberish. <a class="lightbox" href="/secure-uploads/uploads/original/5X/5/b/9/7/5b97d428400f806a4a88…

@sponguswastaken

character limit

The thing is , i already tried this and i just get this result :

Output:

lua5.4: Main.lua:1: attempt to perform arithmetic on a nil value (local ‘l’)
stack traceback:
Main.lua:1: in upvalue ‘n’
Main.lua:1: in upvalue ‘fe’

The script look liks this tho ye , its not working with theses websites

[sponguswastaken (spongus)]

Are you sure? All you seemed to send is some website to run a script that is NOT obfuscated in moonsec that just prints “heyyy”

[Doomcolp (dxxmed)]

Yep you’re right, i was a bit gullible here

Should’ve probably tested something else too. I also don’t really know how I didn’t connect the dots when it printed “heyyy” instead of “Hello world”.

Hey there! Guy who made that post here.
As people have told me within the post, there is unfortunately no easy way to deobfuscate it without prior knowledge in the subject. The only way you can get the deobfuscated code is by being the one who deobfuscated it, or being REALLY good at deobfuscating! I was also very disappointed with the answer, but it is technically possible to deobfuscate it… it’d just be so difficult that I would not recommend trying.
Hope this helps, even if the answer is disappointing xD

lua5.4: Main.lua:1: attempt to perform arithmetic on a nil value (local ‘l’)

this is because you are running it in lua and not luau, and you would still be missing some globals that it uses so if it’s not roblox it doesn’t run.

I can provide some insight into what the obfuscated script does if you contact me (check my profile) and send me the script, i’ll try my best to help you (I may or may not be able to help)
