Tools and Programmatic Support

This page gives an overview of the tools and utilities that are available to help you work with (and learn) CybOX. It does not go into depth on each tool, but links to the in-depth documentation for that tool directly.

Most of these tools are provided directly by the CybOX project, but if the community develops and publishes a tool we would be happy to link to it here. Note that any tool provided by the CybOX project, with the exception of the bindings, is intended primarily as an illustrative example of what can be done rather than a production-quality capability.

User-level Tooling

User-level tooling can help abstract away the CybOX XML and provide you with different views or capabilities for working with CybOX that may not require you to know XML at all. Currently, the CybOX project provides the CybOX-to-HTML tool to present CybOX XML instance documents in a more readable manner.


CybOX-to-HTML is an XSLT stylesheet that can take a CybOX XML document and turn it into a more readable HTML view.

That said, the XSLT is easy enough to use if you understand how it works and if you run it directly it’s easy to transform dozens of CybOX documents at once.

Developer Tools and Utilities


The Email-to-CybOX tool is written in Python and used to convert email (MIME documents) into CybOX Observable documents. It can parse out IP address information from the message contents and perform whois and DNS lookups, as well as convert the Email message structure into the CybOX format.


OpenIOC-to-CybOX is a Python utility to convert Mandiant’s OpenIOC format into CybOX Observables.

While useful for it’s stated purpose, the other way to use this tool is as an example of how to generate CybOX content programatically using the bindings. Looking through the source code is a great way to see how they work and how to import/use them.


The X.509-to-CybOX utility is written in Python and converts X.509-compliant certificates into CybOX Observable documents.


The CybOX-to-OVAL utility is written in Python and translates CybOX Observable documents, containing CybOX Objects to the Open Vulnerability and Assessment Language (OVAL™).

Programmatic Support


The CybOX project currently provides bindings and higher-level APIs to the CybOX Language through the python-cybox project.

Community-Developed Tools

The tools and libraries listed below are developed by CybOX community members and offer the ability to parse, create, edit, or otherwise make use of CybOX documents. We would love to have more entries in this section, so if you’d like to see yours included, please let us know by by subscribing and submitting comments to the CTI Users List or the CTI TC Public Comment List!


The IOCextractor is a Python utility developed by Stephen Brannon which includes support for exporting CybOX Observables. Its documentation states the following:

IOC (Indicator of Compromise) Extractor: a program to help extract IOCs from text files. The general goal is to speed up the process of parsing structured data (IOCs) from unstructured or semi-structured data (like case reports or security bulletins).
