MITRE Threat Explorer™: The Complete AI Threat Intelligence Knowledge Base (2026)

Most organisations know about prompt injection. Far fewer understand retrieval poisoning, agent memory corruption, autonomous workflow manipulation, or AI supply chain attacks. The MITRE Threat Explorer™ makes the full MITRE ATLAS framework searchable, visual, and actionable — for everyone from red teams to compliance officers.

Searchable database of 20+ MITRE ATLAS techniques with attack paths, kill chains, sandbox simulations, and mitigation guidance. Free, no signup required.

Why Traditional Threat Intelligence Falls Short for AI

Security teams already have threat intelligence platforms, SIEM solutions, vulnerability databases, and MITRE ATT&CK. These work well for traditional cybersecurity. But AI introduces attack categories that appear nowhere in traditional frameworks. You can't look up "retrieval poisoning" in a CVE database. You can't find "agent memory corruption" in ATT&CK. You can't query a SIEM for "autonomous workflow manipulation."

This is the gap MITRE ATLAS fills — and the gap MITRE Threat Explorer™ makes navigable.

What Is MITRE ATLAS?

MITRE ATLAS — Adversarial Threat Landscape for Artificial Intelligence Systems — is the leading public framework for AI-specific attack techniques. Developed by MITRE (the same organisation behind ATT&CK), ATLAS catalogues how adversaries target AI systems throughout their lifecycle: during training, at inference time, through retrieval systems, via agent tool integrations, and through supply chain compromise.

ATLAS organises techniques into tactics (the "why") and techniques (the "how"). Understanding both is essential for building AI security controls that address the actual attack surface, not just what looks familiar from traditional cybersecurity.

MITRE ATLAS vs MITRE ATT&CK

ATLAS is best understood as the AI-specific counterpart to MITRE ATT&CK, the long-established framework for traditional IT threats. Security teams already running ATT&CK-based threat intelligence, SIEM rules, and vulnerability management need a separate, complementary framework for AI — the two cover fundamentally different attack surfaces and don't substitute for one another.

You can't look up "retrieval poisoning" in a CVE database. You can't find "agent memory corruption" in ATT&CK. ATLAS exists specifically to fill that gap — and every technique ID referenced throughout HexTyx scan findings (AML.T0051, AML.T0054, AML.T0020, and others) traces back to this taxonomy, giving your findings a standardised reference point auditors and security teams already recognise.

Major AI Threat Categories in MITRE ATLAS

Prompt Injection

The most common AI attack category. Adversaries craft inputs to override intended model behaviour.

AML.T0051 — LLM Prompt Injection AML.T0054 — Indirect Prompt Injection

AI Agent Abuse

Exploiting autonomous agents' tool access, memory, and workflow execution capabilities.

AML.T0080 — Agent Tool Abuse AML.T0090 — Memory Poisoning

️ Retrieval Poisoning

Manipulating RAG knowledge bases to influence AI outputs or expose sensitive data.

AML.T0020 — Training Data Poisoning AML.T0086 — RAG Manipulation

Data Leakage

Extracting sensitive information through AI outputs, retrieval systems, or cross-tenant exposure.

AML.T0057 — LLM Data Disclosure AML.T0060 — Cross-Context Leakage

Model Theft

Extracting proprietary model capabilities, weights, or training data through repeated queries.

AML.T0006 — Model Stealing AML.T0005 — Model Inversion

AI Supply Chain

Compromising AI components at the source — foundation models, plugins, MCP servers, dependencies.

AML.T0010 — ML Supply Chain Compromise AML.T0110 — Dependency Poisoning

Who Should Use the Threat Explorer?

Red teams and penetration testers — use it to build AI attack scenarios mapped to real ATLAS techniques. The kill chains section shows how adversaries combine multiple techniques into a complete attack campaign.

Security architects — use it to design AI security controls against the actual attack surface, not just generic best practices. Each threat page links to the specific mitigations most effective against that technique.

Compliance teams — use it to map MITRE ATLAS coverage to NIST AI RMF, OWASP LLM Top 10, and EU AI Act requirements. The framework mappings on each threat page make this explicit.

CISOs and AI security leads — use it alongside the MITRE ATLAS Coverage Calculator™ to identify which techniques your organisation is currently uncovered against, and prioritise investments accordingly.

From Intelligence to Coverage Measurement

After exploring threats in the Threat Explorer, use the Coverage Calculator to score how well your organisation covers the full MITRE ATLAS framework.

Frequently Asked Questions

What is MITRE ATLAS?
MITRE ATLAS (Adversarial Threat Landscape for Artificial Intelligence Systems) is the leading public framework for understanding AI-specific attack techniques. It catalogues how adversaries target machine learning systems, large language models, autonomous agents, AI infrastructure, training pipelines, and retrieval systems — with tactics, techniques, procedures, and defensive guidance.
How is MITRE ATLAS different from MITRE ATT&CK?
ATT&CK covers attacks against traditional IT infrastructure — servers, endpoints, networks. ATLAS covers attacks specifically against AI and ML systems. The two are complementary: organisations deploying AI need ATT&CK for infrastructure and ATLAS for AI systems. ATLAS includes AI-specific tactics like ML Attack Staging and techniques like prompt injection that have no ATT&CK equivalent.
Is the Threat Explorer free?
Yes — fully free, no account required. The MITRE Threat Explorer™ is part of HexTyx's free tool suite alongside the MITRE ATLAS Coverage Calculator™ and the AI Security Assessment™.
How many ATLAS techniques are covered?
The current database covers 20+ key MITRE ATLAS techniques with full attack profiles. MITRE ATLAS itself contains over 70 techniques — the Threat Explorer focuses on the highest-impact, most commonly exploited techniques in 2026, with ongoing additions as new attack patterns emerge.
