Wed, 05/08/2013 - 19:21 — decalage

python-oletools is a package of python tools to analyze Microsoft OLE2 files (also called Structured Storage, Compound File Binary Format or Compound Document File Format), such as Microsoft Office documents or Outlook messages, mainly for malware analysis and debugging. It is based on the OleFileIO_PL parser. 

Note: python-oletools is not related to OLETools published by BeCubed Software.

Tools in oletools:

  • olebrowse: A simple GUI to browse OLE files (e.g. MS Word, Excel, Powerpoint documents), to view and extract individual data streams.
  • oleid: a tool to analyze OLE files to detect specific characteristics that could potentially indicate that the file is suspicious or malicious.
  • pyxswf: a tool to detect, extract and analyze Flash objects (SWF) that may be embedded in files such as MS Office documents (e.g. Word, Excel) and RTF, which is especially useful for malware analysis. pyxswf is an extension of xxxswf.py published by Alexander Hanel.
  • rtfobj: a tool and python module to extract embedded objects from RTF files.
  • and a few others (coming soon)
