Once you have successfully extracted the archive, you will get .pyc files (compiled Python bytecode). To recover the original source code, use:
If binwalk finds a ZIP archive at some offset, you can extract it manually using dd or a tool like 7zip . However, the cookie is still required to reconstruct the full Python bytecode.
Packages assets and bytecode into resources differently than PyInstaller.

This tool automatically detects the PyInstaller version and extracts the archive correctly.
If all signs point to the file not being a PyInstaller executable, you need to identify the actual packer or build tool.

PyInstaller bundles a Python script into a standalone executable by:

If you can’t find any recognizable magic bytes, the file is either not a PyInstaller executable or is packed.
Knowing the exact PyInstaller version that created the executable helps you choose the correct extractor.
