Misp Project

MISP, the Malware Information Sharing Platform, is an open source threat intelligence platform used by governments, CERTs, financial institutions, and security teams to collect, store, correlate, and share indicators of compromise and threat intelligence. Originally developed by the Belgian defence community, MISP has become the standard open source platform for structured threat intelligence sharing across organizational boundaries.

What OSINT investigators and threat analysts use MISP for: storing and correlating IOCs across investigations, sharing threat intelligence with trusted communities through MISP feeds, pivoting from a single indicator to related malware families and threat actors, and enriching raw indicators with contextual data from automated feeds.

What MISP provides: a flexible data model based on events and attributes that can represent any type of threat indicator, galaxy clusters for linking indicators to threat actor groups and attack patterns, the MISP taxonomies for consistent classification, integration with the MITRE ATT&CK framework, and standardized sharing formats including STIX and OpenIOC.

MISP's sharing capabilities are its defining feature. Organizations can join MISP communities and automatically receive intelligence feeds from other members, enriching their local data with indicators observed by peers. Feeds from well-known threat intel providers, government CERTs, and commercial vendors are available in MISP format for automatic import.

Correlation engine: when a new IOC is added to MISP, the platform automatically checks whether it has appeared in previous events. An IP address that was part of one investigation may be linked to a different campaign reported by another organization, revealing connections that would be invisible in siloed databases.

For OSINT integration: MISP can ingest data from OSINT feeds, social media monitoring, and manual investigation findings. Its API allows automated enrichment using external tools, and its event model supports recording the full context of an investigation including analyst notes and confidence levels.

In a workflow: after collecting IOCs from a threat investigation using tools like VirusTotal, Shodan, and theHarvester, import them into MISP for correlation and sharing. Query MISP feeds before starting a new investigation to check whether related indicators have been seen previously. Use ATT&CK galaxy clusters to map findings to known threat actor profiles.
