MISP, Malware Information Sharing Platform and Threat Sharing, is an open source software solution for collecting, storing, distributing and sharing cyber security indicators and threat about cyber security incidents analysis and malware analysis. MISP is designed by and for incident analysts, security and ICT professionals or malware reverser to support their day-to-day operations to share structured informations efficiently.

The objective of MISP is to foster the sharing of structured information within the security community and abroad. MISP provides functionalities to support the exchange of information but also the consumption of the information by Network Detection Intrusion System (NIDS), LIDS but also log analysis tools, SIEMs.

MISP, Malware Information Sharing Platform and Threat Sharing, core functionalities are:

• An efficient IOC and indicators database allowing to store technical and non-technical information about malware samples, incidents, attackers and intelligence.
• Automatic correlation finding relationships between attributes and indicators from malware, attacks campaigns or analysis.
• Built-in sharing functionality to ease data sharing using different model of distributions. MISP can synchronize automatically events and attributes among different MISP. Advanced filtering functionalities can be used to meet each organization sharing policy including a flexible sharing group capacity and an attribute level distribution mechanisms.
• An intuitive user-interface for end-users to create, update and collaborate on events and attributes/indicators. A graphical interface to navigate seamlessly between events and their correlations.
• storing data in a structured format (allowing automated use of the database for various purposes) with an extensive support of cyber security indicators along fraud indicators as in the financial sector.
• export: generating IDS, OpenIOC, plain text, CSV, MISP XML or JSON output to integrate with other systems (network IDS, host IDS, custom tools)
• import: bulk-import, batch-import, import from OpenIOC, GFI sandbox, ThreatConnect CSV.
• Flexible free text import tool to ease the integration of unstructured reports into MISP.
• A gentle system to collaborate on events and attributes allowing MISP users to propose changes or updates to attributes/indicators.
• data-sharing: automatically exchange and synchronization with other parties and trust-groups using MISP.
• Flexible API to integrate MISP with your own solutions. MISP is bundled with PyMISP which is a flexible Python Library to fetch, add or update events attributes, handle malware samples or search for attributes.
• Adjustable taxonomy to classify and tag events following your own classification schemes or existing classification. The taxonomy can be local to your MISP but also shareable among MISP instances.
• STIX support: export data in the STIX format (XML and JSON).

Exchanging info results in faster detection of targeted attacks and improves the detection ratio while reducing the false positives. We also avoid reversing similar malware as we know very fast that others team or organizations who already analyzed a specific malware.
