MISP (Malware Information Sharing Platform)

MISP is an open-source threat intelligence platform designed to facilitate the collection, analysis, and sharing of Indicators of Compromise (IOCs) and threat data across trusted communities. Built by and for security analysts, it supports structured collaboration across SOCs, CERTs, and CTI teams.

Primary Use Cases:

Threat intelligence sharing
Malware analysis and reverse engineering
Forensics and incident response
Security automation and enrichment
Cross-organizational collaboration

Core Capabilities

Function	Description
Event Management	Analysts can create and manage events tied to incidents or campaigns. Events are containers for attributes and context.
Attribute Handling	Stores technical and contextual data: IPs, hashes, domains, YARA rules, malware family tags, etc.
Correlation Engine	Detects relationships across attributes and events (e.g., same IP seen across multiple events). Supports fuzzy matching, CIDR range correlation, etc.
Event Graphs	Visualizes object and attribute relationships using node-link graphs.
Sharing Controls	Flexible distribution levels: private, community, connected networks, or public.
Tagging & Taxonomy	Use tags, classifications (e.g., TLP, threat actor, confidence level) to organize and label threat data.
Import & Export	Supports STIX (v1/v2), OpenIOC, CSV, JSON, Suricata, Zeek, Snort, and many more.
API Access	Enables automation, feed ingestion, and integration with SIEMs, SOARs, and other tooling.

Event Lifecycle in MISP

Step 1: Event Creation

Events are containers for threat intelligence related to a security incident.
Analysts define metadata: event title, timestamp, threat level, distribution scope.
Distribution Options:
- Your Organization Only
- Community Only
- Connected Communities
- All Communities

Step 2: Add Attributes

Attributes = individual data points (e.g., IP: 192.168.1.1, sha256:...)
