An open library of adversary emulation plans designed to empower organizations to test their defenses based on real-world TTPs.

Attack Flow helps executives, SOC managers, and defenders easily understand how attackers compose ATT&CK techniques into attacks by developing a representation of attack flows, modeling attack flows for a small corpus of incidents, and creating visualization tools to display attack flows.

TRAM is an open-source platform designed to advance research into automating the mapping of cyber threat intelligence reports to MITRE ATT&CK®.

🚨ATTENTION🚨 The NIST 800-53 mappings have migrated to the Center’s Mappings Explorer project. See README below. This repository is kept here as an archive.

CTI Blueprints is a free suite of templates and tools that helps Cyber Threat Intelligence analysts create high-quality, actionable reports more consistently and efficiently.

🚨ATTENTION🚨 The CVE mappings have migrated to the Center’s Mappings Explorer project. See README below. This repository is kept here as an archive.

The principal objective of this project is to develop a knowledge base of the tactics, techniques, and procedures (TTPs) used by insiders in the IT environment. It will establish an Insider Threat TTP Knowledge Base, built upon data collected on insider threat incidents and lessons learned and experience from the ATT&CK knowledge base.

Pathfinder is a plugin for mapping network vulnerabilities, scanned by CALDERA or imported by a supported network scanner, and translating those scans into adversaries for network traversal.

🚨ATTENTION🚨 The VERIS mappings have migrated to the Center’s Mappings Explorer project. See README below. This repository is kept here as an archive.

Summiting the Pyramid is a research project focused on engineering cyber analytics to make adversary evasion more difficult. The research includes a scoring model, methodology, and worked examples.

Sensor Mappings to ATT&CK is a collection of resources to assist cyber defenders with understanding which sensors and events can help detect real-world adversary behaviors in their environments.

ATT&CK Sync is a Center for Threat-Informed Defense project that aims to improve the ability for organizations to consume MITRE ATT&CK® version updates into their internal systems and processes.

The Measure, Maximize, and Mature Threat-Informed Defense (M3TID) project defines what Threat-Informed Defense (TID) is and the key activities associated with its practice.

Threat Modeling with ATT&CK defines how to integreate MITRE ATT&CK® into your organization’s existing threat modeling methodology.

Defending IaaS with ATT&CK is a project to create a collection of ATT&CK techniques relevant to a Linux IaaS environment, as well as a methodology for creating technique collections.

The CWE Calculator enables software development teams to score and prioritize discovered weaknesses empirically based on data in the National Vulnerability Database (NVD).

MCP server that maps Tenable Security Center findings to the MITRE ATT&CK framework, then lets you ask your LLM (Claude Code) to analyze exposure by specific tactic or technique in plain language — and optionally open the results as an interactive ATT&CK Navigator matrix in a local web viewer.

Detection coverage analytics for MITRE ATT&CK with weighted data-source scoring, Sigma/Wazuh/JSON rule ingestion, and 130+ threat-actor coverage analysis. Streamlit UI, SQLite, ATT&CK Navigator export, PDF reports.
