Mahipal 2fb6a9faff Rewrite 548 skill descriptions to the activation rubric
Each rewritten description now states both what the skill does (concrete
capability, named tools/artifacts) and an explicit when-to-use trigger,
improving agent discovery/activation. Grounded in each skill's own body;
changes confined to the `description` field only (bodies and all other
frontmatter untouched). Produced by a gated audit->rewrite->recheck loop
(548 -> 0 flagged) with a sampled anti-invention check (0 ungrounded).

Schema: 817/817 pass. Framework-ID gate: 0 defects.

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.
