Extract PYZ Error

Question

I successfully recovered some PYC files from an ELF built by PyInstaller (https://github.com/extremecoders-re/pyinstxtractor/wiki/Extracting-Linux-ELF-binaries). There is a PYZ archive in the dump. I tried to use pyi-archive_viewer to open and/or extract some modules from the PYZ. I receive an AttributeError "ZlibArchive object has no attribute open openEmbedded."

The error occurs on line 134 of the source (https://github.com/pyinstaller/pyinstaller/blob/develop/PyInstaller/utils/cliutils/archive_viewer.py)

I believe something is incorrectly parsed/output during extraction...? Has anyone else seen this?

Answer 1

For anyone else this happens to... Ensure you use the same Python version as the original author.

That is, I originally created the ELF with Python 3.7. But I tried the reversing process on a different machine - with Python 3.8. Learn from my mistake!
