AutoIt Obfuscator — AutoIt Script Source Code Obfuscation

AutoIt Obfuscator lets you protect your AutoIt script source code against analysis, reverse engineering & decompilation by using multiple advanced obfuscation techniques and polymorphic encryption.

What is AutoIt?

AutoIt is a scripting language for the Windows platform. It has evolved greatly from its first releases and now it's a mature product capable of creating whole applications, both console and windows based. Over time it has become a powerful language that supports complex expressions, user functions, loops and everything else that veteran scripters would expect.

It is widely used for fast and simple GUI automation tasks. It uses a combination of simulated keystrokes, mouse movement and window/control manipulation in order to automate tasks in a way not possible or reliable with other languages.

AutoIt script source code obfuscation

Obfuscation is the process of transforming AutoIt source code into a protected version of itself. The script functionality stays the same, everything works the same, but the source code is protected from analysis, all of the variables are encrypted, and all strings are encrypted.

AutoIt Obfuscator uses multiple obfuscation strategies to protect the real meaning of your AutoIt source code.

Look at this example and click the "After obfuscation" tab to understand how AutoIt Obfuscator works:

Would you even be able to tell what the obfuscated code does if you didn't have access to the original source code?

AutoIt decompilation

Why should you obfuscate your scripts, you might ask yourself? After all, they are compiled to executable format, right?

Well, what if it was possible to decompile a compiled AutoIt executable back to the source code? In fact, it is possible! Our company provides a source code recovery service that enables you to restore any AutoIt application back to its original source code.

How is it done and why is it possible?

AutoIt code is not compiled to instructions for the CPU. It's not even compiled to bytecode (like .NET or Java programs are).

When an AutoIt script is "compiled" into executable format, its original script source code is stored in its entirety as a resource within the executable file. The rest of the executable contains the AutoIt interpreter.

AutoIt hidden script within the executable file

Thankfully, the source code isn't stored in plain text, otherwise anyone with a simple hex-editor could view it. It's stored in encrypted form, but it's there. With the right tools and knowledge, it's possible to restore it.

That's right — the original source code can be recovered! Just like you would write it in the SciTE code editor. Everything is there, all of the variable names, original strings, algorithms; they are exposed to anyone with a copy of the compiled file and a little know-how. Your competition could easily steal weeks of your hard work.

Sensitive topic on official AutoIt forums

If you try to ask about decompilation on the official AutoIt forums you will get banned. If you ask about how serious this problem is for AutoIt — you will get banned. Joke about it — ban.

Banned from official AutoIt forums for talking about decompilation

Why is it forbidden to ask about decompilation and decompilers for AutoIt? The answer is simple. It's a known weakness of the AutoIt system that the script source code is stored in the executable file. They try as hard as possible to keep this weakness hidden, to sweep it under the rug. As a professional I find this practice very dishonest towards the AutoIt community.

Protect the source code of your AutoIt scripts

If you're writing software, bots, automation scripts or anything else in AutoIt and you want to prevent others from decompiling your work to the original source code form — AutoIt Obfuscator is for you.

How does AutoIt Obfuscator work?

Our solution is built on two basic components. The first is an advanced AutoIt source code parsing library based on work by Matt Diesel. It contains a lexer, AST parser and code generator for AutoIt language syntax. We don't use cheap and buggy regular expressions for source code analysis.

The second component is of course our actual obfuscation engine. It takes the generated AST and applies obfuscation strategies to selected tree nodes. Many of the obfuscation techniques were created specially for AutoIt Obfuscator, but some of the obfuscation strategies and ideas are taken from our other security products like our x86 assembly Obfuscator or the polymorphic string encryption used in our StringEncrypt service.

The process used in AutoIt Obfuscator

After all the modification are done, the AST tree is compiled back to obfuscated source code format. This might sound simple, but it's trickier than you would expect! There are many quirks and traps along the way as well as many corner cases in AutoIt source code parsing and modification.

Bug Bounty

I have tested AutoIt Obfuscator with hundreds of public scripts, examples and all available language constructs, but it might not work in some very rare cases and if you find a bug — please report it to me. If I can confirm your findings I will grant you a free access code to the product as a thank you for your report.

Obfuscation strategies

Tricks and techniques for deliberately obfuscating code, with examples of code before and after obfuscation:

Rename variable names to random string values

Local $variable = 1
Global $var = 12345
Dim $iValue = 0xABBA
Local $nGuiyagSznwgwh = 1
Global $SMGPZHGE_GRUHVBRVUR_TRMWCXZV = 12345
Dim $var_12 = 0xABBA

All references to the renamed variables are automatically fixed.

Rename function names to random string values

Func Example($param1, $param2)
Func ProcessSomething()
Func Dummy($aArray)
Func VadOeCmEiez($param1, $param2)
Func func_91()
Func AvnsnFunc($aArray)

DllCall() and others using function names as a parameter are automatically fixed as long as the parameter is passed as a string (not a variable!).

Rename function names in function calls with randomly named variables

Local $result = Example($param1, $param2)
ProcessSomething()
$out = Dummy($aArray)
ConsoleWrite("Obfuscation for AutoIt")
Local $result = $VsoLkc($param1, $param2)
$DOX_MDK_WAVP()
$out = $aRacmLko($aArray)
$aAxieOjxz("Obfuscation for AutoIt")

Functions in AutoIt can be assigned to variables; this is a good way to hide the real name of called functions.

Shuffle order of functions in the output source

ConsoleWrite(c())

Func a()
    return "Hello!"
EndFunc

Func b()
    return a()
EndFunc

Func c()
    return b()
EndFunc
ConsoleWrite(c())

Func c()
    return b()
EndFunc

Func a()
    return "Hello!"
EndFunc

Func b()
    return a()
EndFunc

The order of AutoIt functions in a script is not important.

Resolve WinAPI constants to numerical values, so they can be obfuscated as integer values

MsgBox($MB_ICONINFORMATION, "Title", "Caption")
MsgBox(64, "Title", "Caption")

Currently more than 15000 Windows API constants are recognized.

Encrypt numeric values into series of arithmetic and boolean expressions

Local $a = 1
Local $value = 1234
Local $lucky_seven = 777
Local $var = 0xFFFF
Local $count = 999
Local $item = 0x100
Local $diabolo = 666
Local $num = 9
Local $alignment = 512
Local $a = 3928 + $EiejcJks[3]
Local $value = (347445640 - 347444406)
Local $lucky_seven = Int(Sqrt(603729))
Local $var = BitXOR(312515813, IbmmftJgowlxa())
Local $count = BitOR(8966, 1033)
Local $item = BitNOT(-257)
Local $diabolo = BitRotate(10911744, 18, "D")
Local $num = 3 * 3
Local $alignment = 2 ^ 9

Arithmetic expressions include the + - * ^ operators and Sqrt() function, boolean expressions include BitXOR, BitOR, BitNOT, and BitRotate functions.

Split strings into series of random sized substrings connected with concatenation operators

ConsoleWrite("Hello World!")
ConsoleWrite('Hello Nasty')
ConsoleWrite("Sample ""quotation"" within")
ConsoleWrite('Single ''quotation'' example')
ConsoleWrite("H" & "ell" & "o " & "W" & "orld" & "!")
ConsoleWrite('Hel' & 'lo Nast' & 'y')
ConsoleWrite("Samp" & "le ""quotation" & """ with" & "in")
ConsoleWrite('Single ' & '''quotati' & 'on''' & ' ' & 'example')

Quoted strings within strings are automatically detected and handled properly.

Modify strings to obfuscate their values using built-it AutoIt string functions

ConsoleWrite("Hello World!")
ConsoleWrite('Hello Bart')
ConsoleWrite('AutoIt Decompilation')
ConsoleWrite(StringReverse("!dlroW olleH"))
ConsoleWrite(StringTrimLeft('KKuqTHello Bart', 5))
ConsoleWrite(StringTrimRight('AutoIt DecompilationX', 1))

String modifications use the built-in StringReverse(), StringTrimRight() and StringTrimLeft() functions.

Encrypt strings using randomly generated polymorphic encryption algorithms

ConsoleWrite("How to protect AutoIt script?")
ConsoleWrite(DlnWck(87, $KQWGAWTNE, $vOedex))
...
Func DlnWck($var_1238, $g_tagNye, $g_v_nCrR)
    Local $6H_TKW[29] = [ 0x728F, 0x6DAF, 0x6CAF, 0x778F, 0x6D0F, _
                          0x6DAF, 0x778F, 0x6D8F, 0x6D4F, 0x6DAF, _
                          0x6D0F, 0x6EEF, 0x6F2F, 0x6D0F, 0x778F, _
                          0x736F, 0x6CEF, 0x6D0F, 0x6DAF, 0x726F, _
                          0x6D0F, 0x778F, 0x6D2F, 0x6F2F, 0x6D4F, _
                          0x6E6F, 0x6D8F, 0x6D0F, 0x73AF ]
    For $NYwQb = 0 To 28
        $Cwium = $6H_TKW[$NYwQb]
        $Cwium -= 0x7B90
        $Cwium = BitRotate($Cwium, 11, "W")
        $Cwium = BitNOT($Cwium)
        $6H_TKW[$NYwQb] = ChrW(BitAND($Cwium, 0xFFFF))
    Next
    Return _ArrayToString($6H_TKW, "")
EndFunc

The polymorphic string encryption engine is taken from our StringEncrypt solution.

Insert ternary operators for numerical values to make analysis of the obfuscated code harder

Local $a = 1
Local $var = 123
Local $a = ($fBnbFcgx[5] >= $xCsccjis[12] ? 1 : $g_GIqyy)
Local $var = (SqXoFunc() <> $Abv ? $var_2029[3] : 123)

Read more about the ternary operator in AutoIt.

Command line version

AutoIt Obfuscator comes with an additional command line interface.
