stix2 1.3.1

Produce and consume STIX 2 JSON content

cti-python-stix2

This is an OASIS TC Open Repository. See the Governance section for more information.

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 on ReadTheDocs.

Installation

Install with pip:

$ pip install stix2

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.

from stix2 import Indicator

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

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

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": "[file:hashes.md5 ='d41d8cd98f00b204e9800998ecf8427e']",
    "valid_from": "2017-09-26T23:33:39.829952Z"
}""")

print(indicator)

STIX 2.X Technical Specification Support

This version of python-stix2 brings initial support to STIX 2.1 currently at the CSD level. The intention is to help debug components of the library and also check for problems that should be fixed in the specification.

The stix2 Python library is built to support multiple versions of the STIX Technical Specification. With every major release of stix2 the import stix2 statement will automatically load the SDO/SROs equivalent to the most recent supported 2.X Committee Specification. Please see the library documentation for more details.
