Update: oledump.py Version 0.0.54

Filed under: My Software,Update — Didier Stevens @ 0:00

This new version of oledump.py adds a new variable for option -E: %MOFULEINFO%

This variable need to be used together with option -i: it contains the size of the compiled VBA code and the compressed VBA code. For example: 123+65.

There’s a new option (-s) for plugin plugin_http_heuristics: with this option, the plugin ignores space characters (useful for hexadecimal bytes separated by a space character, for example).

And there is a new plugin: plugin_msg_summary. This is a new type of plugin, a plugin that operates on the complete document. Before, plugins could only operate on individual streams, and were instantiated for each stream.

This plugin produces a summary of a .msg file (something we needed for our “Epic Manchego” research).

Here is an example:

This plugin has a couple of options, for example to produce JSON output or to add header or body information:



  1. First of all thank you for providing your excellent tools.

    A more general topic:

    Having analyzed dozens of MS-Office samples (here the focus on OOXML) from the malware-bazaar the question was, is there an easy way to identify the malware without Anti-Virus-software.

    A trial with checking only the magic-bytes, the existence of the elementary components like ‘docProps/core.xml’ etc and the special password “Velvet…” were promising.

    Depending on preferences Python or VBA are possible.

    Is there a chance to test the concept “in real live”?
