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.
Install with pip:
$ pip install stix2
Note: The library requires Python 3.6+.
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",
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()
:
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))

This version of cti-python-stix2 brings support to STIX Version 2.1 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
for details.
