Hi @randubin, this looks similar to #728: could you please update oletools with the following command and tell me if it works?

pip install -U oletools[full]

This will install XLMMacroDeobfuscator, which is now used to detect and extract XLM macros. By default XLMMacroDeobfuscator is not installed by pip. You can also install it separately (see https://github.com/DissectMalware/XLMMacroDeobfuscator).

Thanks for the fast response!.

What is [full]? I tried to update from git or from pip and got the same result. [Made sure that I have the latest version for XLMMacroDeobfuscator pip install -U https://github.com/DissectMalware/XLMMacroDeobfuscator/archive/master.zip
