ioc_writer
Python library for creating, editing, and managing OpenIOC objects for threat intelligence indicators.
What is ioc_writer?
ioc_writer is a Python library developed by Mandiant for creating, editing, and managing OpenIOC (Open Indicators of Compromise) objects. It provides a programmatic interface to generate standardized threat intelligence indicators used in cybersecurity detection and sharing workflows. The library supports CRUD operations for IOC metadata and integrates with tools like YARA for comprehensive threat representation.
Security engineers, threat intelligence analysts, and cybersecurity developers who need to programmatically generate or modify OpenIOC documents for threat detection systems and intelligence sharing platforms.
It offers a specialized, standardized approach to IOC management that integrates seamlessly with existing threat intelligence pipelines, with built-in support for OpenIOC formats and YARA signature encapsulation not found in generic XML libraries.
Overview
ioc_writer is a Python library that provides a programmatic interface for working with OpenIOC (Open Indicators of Compromise) objects. It enables security professionals and threat intelligence analysts to generate, modify, and manage standardized IOC documents used in cybersecurity threat detection and sharing.
Key Features
- CRUD Operations — Supports Create, Read, Update, and Delete operations for IOC metadata including name, description, dates, and parameters.
- OpenIOC Compatibility — Works with OpenIOC 1.0 and 1.1 formats for standardized threat indicator representation.
- XML Manipulation — Built on lxml and ElementTree for efficient XML handling and XPATH querying of IOC components.
- YARA Integration — Includes tools for encapsulating YARA signatures within OpenIOC documents for unified threat representation.
- Format Conversion — Provides utilities for downgrading OpenIOC 1.1 documents to 1.0 format for backward compatibility.
Philosophy
Designed to simplify the programmatic creation and management of OpenIOC documents while maintaining strict adherence to the standard's specifications and structure.
