How to Download and Install python-oletools

Pre-requisites

-

For now, python-oletools require Python 2.x, if possible 2.7 or 2.6 to enable all features.

-

They are not compatible with Python 3.x yet. (Please contact me if that is a strong requirement)

-

To use oletools as command-line tools

-

To use python-oletools from the command line as analysis tools, you may simply download the latest release archive and extract the files into the directory of your choice.

-

You may also download the latest development version with the most recent features.

-

Another possibility is to use a git client to clone the repository (https://github.com/decalage2/oletools.git) into a folder. You can then update it easily in the future.

-

Windows

-

You may add the oletools directory to your PATH environment variable to access the tools from anywhere.

+

The recommended Python version to run oletools is Python 2.7. Python 2.6 is also supported, but as it is not tested as often as 2.7, some features might not work as expected.

+

Since oletools v0.50, thanks to contributions by [@Sebdraven](https://twitter.com/Sebdraven), most tools can also run with Python 3.x. As this is quite new, please report any issue you may encounter.

+ +

Pip is included with Python since version 2.7.9 and 3.4. If it is not installed on your system, either upgrade Python or see https://pip.pypa.io/en/stable/installing/

Linux, Mac OSX, Unix

-

It is very convenient to create symbolic links to each tool in one of the bin directories in order to run them as shell commands from anywhere. For example, here is how to create an executable link "olevba" in /usr/local/bin pointing to olevba.py, assuming oletools was unzipped into /opt/oletools:

-
chmod +x /opt/oletools/oletools/olevba.py
-ln -s /opt/oletools/oletools/olevba.py /usr/local/bin/olevba
-

Then the olevba command can be used from any directory:

-
user@remnux:~/MalwareZoo/VBA$ olevba dridex427.xls |less
-

For python applications

-

If you plan to use python-oletools with other Python applications or your own scripts, the simplest solution is to use "pip install oletools" or "easy_install oletools" to download and install the package in one go. Pip is included with Python since version 2.7.9.

-

Important: to update oletools if it is already installed, you must run "pip install -U oletools", otherwise pip will not update it.

-

Alternatively if you prefer the old school way, you may download the latest archive, extract it into a temporary directory and run "python setup.py install".

+

To download and install/update the latest release version of oletools, run the following command in a shell:

+
sudo -H pip install -U oletools
+

Important: Since version 0.50, pip will automatically create convenient command-line scripts in /usr/local/bin to run all the oletools from any directory.

+

Windows

+

To download and install/update the latest release version of oletools, run the following command in a cmd window:

+
pip install -U oletools
+

Important: Since version 0.50, pip will automatically create convenient command-line scripts to run all the oletools from any directory: olevba, mraptor, oleid, rtfobj, etc.

+

How to install the latest development version

+

If you want to benefit from the latest improvements in the development version, you may also use pip:

+

Linux, Mac OSX, Unix

+
sudo -H pip install -U https://github.com/decalage2/oletools/archive/master.zip
+

Windows

+
pip install -U https://github.com/decalage2/oletools/archive/master.zip
+

How to install offline - Computer without Internet access

+

First, download the oletools archive on a computer with Internet access: * Latest stable version: from https://github.com/decalage2/oletools/releases * Development version: https://github.com/decalage2/oletools/archive/master.zip

+

Copy the archive file to the target computer.

+

On Linux, Mac OSX, Unix, run the following command using the filename of the archive that you downloaded:

+
sudo -H pip install -U oletools.zip
+

On Windows:

+
pip install -U oletools.zip
+

Old school install using setup.py

+

If you cannot use pip, it is still possible to run the setup.py script directly. However, this method will not create the command-line scripts automatically.

+

First, download the oletools archive: * Latest stable version: from https://github.com/decalage2/oletools/releases * Development version: https://github.com/decalage2/oletools/archive/master.zip

+

Then extract the archive, open a shell and go to the oletools directory.

+

Linux, Mac OSX, Unix

+
sudo -H python setup.py install
+

Windows:

+
python setup.py install

    rtfobj.py <file.rtf>
    -

    It extracts and decodes all the data blocks encoded as hexadecimal in the RTF document, and saves them as files named "object_xxxx.bin", xxxx being the location of the object in the RTF file.

    +
    rtfobj [options] <filename> [filename2 ...]
+
+Options:
+  -h, --help            show this help message and exit
+  -r                    find files recursively in subdirectories.
+  -z ZIP_PASSWORD, --zip=ZIP_PASSWORD
+                        if the file is a zip archive, open first file from it,
+                        using the provided password (requires Python 2.6+)
+  -f ZIP_FNAME, --zipfname=ZIP_FNAME
+                        if the file is a zip archive, file(s) to be opened
+                        within the zip. Wildcards * and ? are supported.
+                        (default:*)
+  -l LOGLEVEL, --loglevel=LOGLEVEL
+                        logging level debug/info/warning/error/critical
+                        (default=warning)
+  -s SAVE_OBJECT, --save=SAVE_OBJECT
+                        Save the object corresponding to the provided number
+                        to a file, for example "-s 2". Use "-s all" to save
+                        all objects at once.
+  -d OUTPUT_DIR         use specified directory to save output files.
    +

    rtfobj displays a list of the OLE and Package objects that have been detected, with their attributes such as class and filename.

    +

    When an OLE Package object contains an executable file or script, it is highlighted as such. For example:

    +
    + +
    +

    To extract an object or file, use the option -s followed by the object number as shown in the table.

    +

    Example:

    +
    rtfobj -s 0
    +

    It extracts and decodes the corresponding object, and saves it as a file named "object_xxxx.bin", xxxx being the location of the object in the RTF file.

    How to use rtfobj in Python applications

    -

    Usage as a python module:

    -

    rtf_iter_objects(filename) is an iterator which yields a tuple (index, object) providing the index of each hexadecimal stream in the RTF file, and the corresponding decoded object.

    +

    As of v0.50, the API has changed significantly and it is not final yet. For now, see the class RtfObjectParser in the code.

    +

    Deprecated API (still functional):

    +

    rtf_iter_objects(filename) is an iterator which yields a tuple (index, orig_len, object) providing the index of each hexadecimal stream in the RTF file, and the corresponding decoded object.

    Example:

    -
    import rtfobj
-for index, data in rtfobj.rtf_iter_objects("myfile.rtf"):
-    print 'found object size %d at index %08X' % (len(data), index)
    +
    from oletools import rtfobj
+for index, orig_len, data in rtfobj.rtf_iter_objects("myfile.rtf"):
+    print('found object size %d at index %08X' % (len(data), index))
