The ethics depend entirely on your intent and the ownership of the code in question. Decompiling script for recovery is generally considered acceptable. Decompiling someone else's software to steal their work, bypass licensing, or create a competing product is unequivocally unethical and likely illegal. Always secure permission from the code's owner before attempting decompilation.
If you see only Execute() calls or random variable names, the script was obfuscated—advanced techniques required.

As of 2025, the AutoIt team has stated they will add real encryption to the compiler to preserve the language’s transparency. However, malware authors increasingly use custom packers. The open-source community continues to update MyAut2Exe.

Before diving into decompilation, it's essential to understand what an AutoIt-compiled executable actually is. When you use the AutoIt compiler on a plain-text .au3 script, it produces a standalone .exe file. This file contains two main components: a full AutoIt interpreter (to run the code) and a compiled version of your script in the form of bytecode, which is embedded as a resource within the PE (Portable Executable) file.
: No protection is 100% effective. If someone is determined and skilled enough, they will likely find a way to decompile your script. This is true for any programming language.
There is no shortage of options when looking for an solution. Below is a detailed list of the most reliable and effective decompilation tools available today.
: When a script is compiled, the bytecode is typically compressed and encrypted to prevent easy reading.
