What it does

Performing Threat Intelligence Sharing With Misp is an agent skill from mukul975/Anthropic-Cybersecurity-Skills. Uses PyMISP (the official MISP REST API library) to create events with structured IOCs (IPs, domains, hashes, URLs), enrich them with MITRE ATT&CK tags and galaxy clusters, manage sharing groups and distribution levels, search existing intelligence, and export in STIX 2.1 format. Use when creating, enriching, or sharing threat intelligence events on a MISP instance, or integrating IOC feeds with other platforms.

Its SKILL.md is about 780 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts and reference files (for example `references/api-reference.md` and `scripts/agent.py`).

It sits in Security, covering OSINT. The repository describes itself as: 817 structured cybersecurity skills for AI agents · Mapped to 6 frameworks: MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS, D3FEND, NIST AI RMF & MITRE F3 (Fight Fraud) · agentskills.io…. The licence is Apache-2.0.

When your agent uses it

  • Sharing threat intelligence events on a MISP instance
  • Integrating IOC feeds with other platforms

Example prompts

  • “Use the performing-threat-intelligence-sharing-with-misp skill to use PyMISP (the official MISP REST API library) to create events with structured…”
  • “/performing-threat-intelligence-sharing-with-misp”

Requirements

  • Python 3

Workflow steps

10 steps, taken from the first numbered list in SKILL.md.

  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

What it can do on your machine

Read from SKILL.md and the folder at commit 54a7988. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • pip

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Performing Threat Intelligence Sharing With Misp loads about 776 tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 116 tokens; SKILL.md has 296 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~116
When it runs · the whole SKILL.md, loaded when a task matches
~776
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

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.
