cti-python-stix2

This is the MISP core team STIX2 library forked from the OASIS TC Open Repository <https://www.oasis-open.org/resources/open-repositories/>__.

This repository provides Python APIs for serializing and de-serializing STIX2 JSON content, along with higher-level APIs for common tasks, including data markings, versioning, and for resolving STIX IDs across multiple data sources.

For more information, see the documentation <https://stix2.readthedocs.io/>__ on ReadTheDocs.

Installation

Install with pip <https://pip.pypa.io/en/stable/>__:

.. code-block:: bash

$ pip install misp-lib-stix2

Note: The library requires Python 3.7+.

Usage

To create a STIX object, provide keyword arguments to the type's constructor. Certain required attributes of all objects, such as type or id, will be set automatically if not provided as keyword arguments.

.. code-block:: python

from stix2 import Indicator

indicator = Indicator(name="File hash for malware variant",
                      indicator_types=["malicious-activity"],
                      pattern_type="stix",
                      pattern="[file:hashes.md5 = 'd41d8cd98f00b204e9800998ecf8427e']")

To parse a STIX JSON string into a Python STIX object, use parse(). To serialize a STIX object, use serialize():

.. code-block:: python

from stix2 import parse

indicator = parse("""{
    "type": "indicator",
    "spec_version": "2.1",
    "id": "indicator--dbcbd659-c927-4f9a-994f-0a2632274394",
    "created": "2017-09-26T23:33:39.829Z",
    "modified": "2017-09-26T23:33:39.829Z",
    "name": "File hash for malware variant",
    "indicator_types": [
        "malicious-activity"
    ],
    "pattern_type": "stix",
    "pattern_version": "2.1",
    "pattern": "[file:hashes.md5 ='d41d8cd98f00b204e9800998ecf8427e']",
    "valid_from": "2017-09-26T23:33:39.829952Z"
}""")

print(indicator.serialize(pretty=True))

STIX 2 Technical Specification Support

This version of cti-python-stix2 brings support to STIX Version 2.1 <https://docs.oasis-open.org/cti/stix/v2.1/os/stix-v2.1-os.html>__ published on 10 June 2021 currently at the Committee Specification (CS) 03 level, also know as the "OASIS Standard".

The stix2 Python library supports multiple versions of the STIX 2 Technical Specification. The library will be updated to support new Committee Specification Drafts (CSDs) as they are released, but modules for these versions must be imported manually until the CSD reaches CS level. In new major releases of stix2 the import stix2 implicit import statement will be updated to automatically load the STIX Objects equivalent to the most recently supported CS. Please see the library documentation <https://stix2.readthedocs.io/en/latest/guide/ts_support.html>__ for details.
