Several free AutoIt script decompilers are available online. Some of the most popular ones include:

AutoIt is a powerful scripting language widely used for automating repetitive Windows tasks, malware analysis, and rapid software prototyping. Because AutoIt scripts are compiled into standalone executable files ( .exe ), developers often face situations where they lose their original source code and need to recover it. Conversely, security researchers frequently encounter compiled AutoIt scripts used by malicious actors and must reverse-engineer them to understand their behavior.

The tool itself is often an obfuscated malware dropper designed to steal your browser passwords or install crypto-miners.

: Before attempting decompilation on an unknown file, test your chosen decompiler on a simple AutoIt script that you compiled yourself. This validates that your tool is working correctly.

Yes, free full tools exist to reverse AutoIt executables, though their availability and effectiveness depend heavily on the version of AutoIt used to compile the script. 1. The Official Exe2Aut Tool (Legacy)

Before compiling your script, run it through an obfuscator like Au3Stripper (included with the full SciTE4AutoIt3 package). This removes all comments, changes your descriptive variable/function names into random strings, and randomizes code flow.

Pause the process immediately after execution using a debugger breakpoint.

To understand decompilation, you must first understand how AutoIt builds an executable.

MyAutToExe is an open-source, community-driven decompiler designed to handle various versions of AutoIt executables. It attempts to parse the compiled file, locate the script resource payload, and decrypt it back into plain text.

One of the more robust solutions for protecting AutoIt code is , which uses:
