Cyber Threat Intelligence with MISP: Part 1 – What is MISP?

Threat Intelligence with MISP Part 1 - What is MISP

Cyber threat intelligence (CTI) is the art of gathering, analyzing, and understanding information about cyber security threats. It involves collecting data, transforming it into actionable intelligence, and distributing it to key stakeholders to improve your organization’s security posture.

To do this effectively, you need a platform to store and analyze the intelligence you collect. You could choose anything from a simple Excel spreadsheet to a custom-made SQL database with a web GUI. However, the defacto solution in the world of CTI is MISP, an open-source threat intelligence platform designed for ingesting, analyzing, and sharing intelligence. 

This article describes MISP, its key features and capabilities, and how it is used by threat intelligence analysts, security researchers, and incident responders. It also details resources where you can learn how to use the platform. That said, this is just the first installment in a series of how to get up and running with MISP. Read on to discover what you will learn by following this series.

Let’s start by learning what MISP is and how it could benefit you.

Overview

MISP (Malware Information Sharing Platform and Threat Sharing) is an open-source threat intelligence platform that allows you to share, collate, analyze, and distribute threat intelligence. It is used by finance, healthcare, telecommunications, government, and technology organizations to share and analyze information about the latest threats. Security researchers, threat intelligence teams, incident responders, and the wider cyber security community all use MISP to collaborate in their defensive efforts. 

The platform provides a structured and standardized framework for collecting, storing, and sharing threat intelligence data, enabling collaboration and enhanced defense against cyber threats. It has mappings with existing threat intelligence frameworks (e.g., MITRE ATT&CK, CAPEC, etc.) and strong integrations with security products (e.g., CrowdStrike Falcon, Intel471, etc.). MISP is the defacto open-source threat intelligence platform mature organizations use to track threats and collaborate.

Key Features and Capabilities

MISP boasts a range of features to aid in collecting, analyzing, and distributing threat intelligence. These include:

  • Data Ingestion: You can import and aggregate threat intelligence data into MISP from various sources, including open-source feeds, proprietary feeds, internal data, and manual input.
  • Data Structuring: The platform uses a structured data model to classify and organize threat intelligence information using Events, Attributes (IOCs), and Objects (attack patterns, malware characteristics, and more).
  • Information Sharing: You can automatically or manually share threat intelligence with trusted partners, peer organizations, and information-sharing communities to collaborate in your detection and mitigation efforts.
  • Taxonomies: MISP incorporates standardized taxonomies and classification systems, including the Common Attack Pattern Enumeration and Classification (CAPEC), Common Vulnerability Enumeration (CVE), and the MITRE ATT&CK matrix for consistency in your threat intelligence.
  • Data Enrichment: You can enrich your threat intelligence from inside the MISP platform by adding contextual information, including threat actor profiles, mitigation strategies, and references to relevant reports and indicators.
  • Customization: You can customize your MISP instance to suit their specific needs.
  • Integration: MISP offers pre-built integrations with various security tools and platforms. You can use these integrations to automate your threat intelligence’s ingestion, enrichment, and distribution. 
  • Analysis and Correlation: MISP uses a correlation engine that automatically analyzes and correlates related threat intelligence so you can quickly identify patterns, trends, and potential threats to your organization.
  • Alerting and Reporting: MISP provides alerting mechanisms to notify you of specific threat intelligence events or indicators. You can also automatically generate and export reports to share your findings with others.
  • API Access: You can use MISP’s RESTful API and associated Python module to programmatically access its functionalities and easily integrate with other security tools and systems.

Use Cases

Now you know what MISP is, let’s look at how it is commonly used by cyber threat intelligence analysts, security researchers, and incident responders in their day-to-day work.

Use Case #1: Cyber Threat Intelligence Analysts

Threat intelligence analysts use MISP to collect, analyze, and share information about cyber threats. MISP serves as a central repository for collecting and sharing intelligence across organizations and industries. Analysts will gather threat intelligence manually or automatically using MISP’s ingestion capabilities and then analyze this data.

To help analyze data, MISP provides enrichment integrations to provide additional context to events automatically. For instance, according to popular CTI vendors, is a domain name malicious, is an IP address originating from a certain country, or has a file’s hash been seen in a malware sandbox before? All this information helps an analyst determine if an IOC is malicious and provides additional data they can investigate further by pivoting. 

Once an analyst is finished analyzing, they can distribute this information to key stakeholders using MISP’s advanced sharing features:

  • IOCs can be pushed to security solutions to be blocked.
  • Reports can be generated and shared with executives.
  • MISP events can be automatically shared with the wider cyber security community.

Use Case #2: Security Researchers

Security researchers will use MISP to collect and share information about the latest vulnerabilities, exploits, and threats across the cyber landscape. They will collect what is being shared to aid in their research and share their research with the community so organizations can protect themselves from attacks.

MISP’s integrations and support for CTI taxonomies/frameworks (MITRE ATT&CK, CVE, CAPEC, etc.) allow researchers to use a common language when describing and classifying threats. For instance, a researcher may investigate a new form of malware and list all the IOCs they found, the MITRE ATT&CK techniques the malware used, and the CVEs the malware exploited. Once shared with the wider community, an organization can use this information to block the IOCs, write detections for specific MITRE ATT&CK techniques, and prioritize the patching of certain CVEs.

Use Case #3: Incident Responders

Incident responders will use MISP to share information about incidents they have experienced or are currently trying to resolve. By sharing this information, a collective effort can be geared towards combating a new threat actor, malware strain, phishing campaign, or any other cyber threat. 

MISP’s correlation engine is ideal for sharing incident data as it allows responders to quickly see incidents that may be related to what they are experiencing. They can then search for specific artifacts or block certain IOCs seen in similar incidents to minimize the impact of their incident.
