: Very newer versions (v3.2.6.0+) use binary bytecode instead of plain source, making basic "hacked" decompilers ineffective; modern tools must rebuild the source from this bytecode . Decompiling FAQ - AutoIt Wiki
If you want a tool that is less controversial and more focused on safety, the AutoIt Extractor is an excellent alternative. It distinguishes itself by emphasizing a non-executing approach.
Understanding AutoIt Script Decompilation: Tools, Realities, and Code Security
Use these tools primarily to recover source code for your own projects.
MyAut2Exe / AutoIt3Wrapper unpack techniques
Wrap your compiled AutoIt executable inside a third-party protective packer or protector (such as VMProtect or Themida). These tools encrypt the entire executable file and use advanced anti-debugging techniques to prevent tools like x64dbg from dumping the memory. Conclusion
: Most GUI tools (like Exe2Aut) allow you to drop the .exe directly onto the interface .
Historically, the official AutoIt installation package included a tool called . This official utility allowed developers to freely select any compiled AutoIt executable and instantly reverse it back into an .au3 file. However, because malicious actors began abusing this feature to reverse-engineer software and steal intellectual property, the AutoIt development team officially discontinued Exe2Aut and hardened their encryption algorithms starting with version 3.2.6.0. 2. The Modern Era (AutoIt v3.3.0.0 to Present)
Look under folders labeled RCData or custom resource strings. If the script wasn't heavily compiled or protected, you may find the raw code strings sitting plainly inside the file resources. Obstacles to Successful Decompilation
