About performing-threat-intelligence-sharing-with-misp

A security skill for sharing threat intelligence through MISP using PyMISP. It supports structured IOC handling, ATT&CK tagging, event search, feed synchronization, and STIX 2.1 export for security teams.

Key features

  1. 01Create and publish MISP events
  2. 02Manage IOC attributes and tags
  3. 03Search existing intelligence
  4. 04Configure feeds and synchronization
  5. 05Export events as STIX 2.1

Use cases

  1. 01Sharing incident IOCs with partner groups
  2. 02Enriching events with ATT&CK techniques
  3. 03Checking new indicators against existing events
  4. 04Exporting intelligence for other platforms

Install

Performing Threat Intelligence Sharing with MISP

Overview

MISP (Malware Information Sharing Platform) is an open-source threat intelligence platform designed for collecting, storing, distributing, and sharing cybersecurity indicators and threat information. PyMISP is the official Python library for interacting with MISP instances via the REST API, enabling programmatic event creation, attribute management, tag assignment, galaxy cluster attachment, and feed synchronization. This skill covers using PyMISP to create events with structured IOCs (IP addresses, domains, file hashes, URLs), enrich events with MITRE ATT&CK tags, manage sharing groups and distribution levels, search for existing intelligence, and export in STIX 2.1 format for interoperability with other platforms.

When to Use

  • When conducting security assessments that involve performing threat intelligence sharing with misp
  • When following incident response procedures for related security events
  • When performing scheduled security testing or auditing activities
  • When validating security controls through hands-on testing

Prerequisites

  • MISP instance (v2.4+) with API access enabled
  • Python 3.9+ with pymisp (pip install pymisp)
  • MISP API key (Settings > Auth Keys)
  • Understanding of MISP data model (Events, Attributes, Objects, Tags, Galaxies)
  • Knowledge of TLP marking and sharing protocols

Steps

  1. Install PyMISP: pip install pymisp
  2. Initialize ExpandedPyMISP(url, key, ssl=True) connection
  3. Create a MISPEvent with info, distribution level, threat level, and analysis status
  4. Add attributes via event.add_attribute(type, value) for IPs, domains, hashes
  5. Apply TLP tags and MITRE ATT&CK technique tags
  6. Publish the event with misp.publish(event)
  7. Search existing events with misp.search(controller='events', value=..., type_attribute=...)
  8. Enable and configure threat feeds for automatic IOC ingestion
  9. Export events in STIX 2.1 format for cross-platform sharing
  10. Validate sharing group configuration and sync server settings

Expected Output

A JSON report summarizing events created, attributes added, tags applied, feed sync status, and any correlation hits against existing intelligence, with event IDs and distribution metadata.
