   - Need the .Net Framework 4 to Use ProtectIT (Already on 70% of Windows PC)

   - Coded in C#

   - Need Winrar to open this .exe

Your Original Code

AutoIt Version: 3.3.6.1
 Author:         COB

 Script Function:
    TEST AUFUSCOB

#ce ----------------------------------------------------------------------------

; Script Start - Add your code below here
test()
test2()
Func test()
    If (1 = 1) Then
        If (0 = 0) Then
            Local $Atrue = 'Condition toujour vrai'
        Else
            $Atrue = "Erreur"
        EndIf
        MsgBox(0, Default, $Atrue)
    EndIf
    Local $msg
    $msg = "Test"
    $msg &= " Msg"
    $msg &= "Box"
    MsgBox(0, Default, $msg)
EndFunc   ;==>test
Func test2()
    $autrevar = "Autre fonction";
    MsgBox(0, "", $autrevar)
EndFunc   ;==>test2

Please delete this tool, it's against the terms of services of autoit, modified the orginal AutoIt3.exe

The ToS is about modifying the AutoIt3.exe file, not the executable you compile yourself.

If you think there is an issue with a thread, please report it and allow a moderator to take action.

I tried running this but every time I would obfuscate a file with it, my AV would kill it (EDIT: The resulting executable and the tool).  Could be a false positive.

Hi Isosmart, Did you write it yourself?Still able to decompile scripts made with versions below 3.3.9.x

I would be careful mentioning that you personally checked its validity against decompilers Emiel ;) , its an obfuscator I believe the op means that it might delay reverse engineering a little.

Ed: After checking it out it is way more than just an obfuscator.

@Mobius i agree with you, the more options the better.
@Isosmart the executable you posted did not work here.

therein lies the riddle:

If posts on obfuscation are encouraged and allowed but mentioning the word decompile gets you chastised and threatened, then how do you test and relay the effectiveness of such a solution?

boththose,

There is no riddle.

Obfuscation (as practiced by Obfuscator and as demonstrated in the snippets posted above by the OP) has never and will never be a problem. All that is changed is the script itself. :)

Altering an already compiled exe to prevent decompilation is also not a problem - several threads have been allowed showing how this might be done. However, we are certainly not going to to give official blessing to anything which might act in such a manner - it is for the individual to test them and decide whether they are suitable. And as has been already been pointed out, mentioning decompilation is best avoided here - a good reason for the results of any such tests to remain private. ;)

What is a problem is altering the AutoIt3.exe or Aut2Exe.exe executables - that is against the EULA. :naughty:

We are still testing this particular offering to decide where it falls in the spectrum. :)

hahahahahahahahahahaha sorry Vlad... :sweating:  i forgot you are a MVP Cheer M8

My bad Emiel ;)

I was wrong to say it was merely an obfuscator, it does much more than that.

You were right in what you said in your original post, it is version specific because its patch mechanism works through offsets, so to enable the tool to work for versions other than 3.3.6.1 and 3.3.8.1 you would have to make your own offset map profile for the version you want.
