Update: oledump.py Version 0.0.67

Filed under: My Software,Update — Didier Stevens @ 10:12

This new version of oledump.py brings support for user defined properties and an update to plugin plugin_msg_summary.py

Office documents with VSTO applications have user defined properties. These properties can be extracted with my plugin plugin_medata.py, but not with the current version of olefile.
However, the development version of olefile can be used to extract these properties. This new version of oledump checks if the olefile module has a function to extract user defined properties (get_userdefined_properties), and if it does, it calls it when analyzing metadata:

Figure: oledump option -M with olefile supporting get_userdefined_properties
Figure: plugin_metadata

I added URL extracting to my plugin plugin_msg_summary, a plugin to summarize the content of an .msg file (Outlook email).
