python-oletools

PyPI Build Status Say Thanks!

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 97-2003 documents, MSI files or Outlook messages, mainly for malware analysis, forensics and debugging. It is based on the olefile parser.

It also provides tools to analyze RTF files and files based on the OpenXML format (aka OOXML) such as MS Office 2007+ documents, XPS or MSIX files.

For example, oletools can detect, extract and analyse VBA macros, OLE objects, Excel 4 macros (XLM) and DDE links.

See http://www.decalage.info/python/oletools for more info.

Download and Install:

The recommended way to download and install/update the latest stable release of oletools is to use pip:

This should automatically create command-line scripts to run each tool from any directory: olevba, mraptor, rtfobj, etc.

The keyword [full] means that all optional dependencies will be installed, such as XLMMacroDeobfuscator. If you prefer a lighter version without optional dependencies, just remove [full] from the command line.

To get the latest development version instead:

See the documentation for other installation options.

Documentation:

The latest version of the documentation can be found online, otherwise a copy is provided in the doc subfolder of the package.
