Mitre-Att&ck

Cybersecurity Framework

Definition

MITRE ATT\&CK is a **public, living knowledge base** of the tactics, techniques, and procedures (TTPs) that real-world adversaries use during cyberattacks.

It’s maintained by **MITRE Corporation**, a U.S. nonprofit that works on security research. ATT\&CK stands for **Adversarial Tactics, Techniques, and Common Knowledge**. The framework breaks down attacks into **tactics** (the “why”), **techniques** (the “how”), and **sub-techniques** (specific details), all mapped in a way that helps defenders understand and detect malicious behavior.

The structure looks like a big matrix:

* **Tactics** – The columns (goals like Initial Access, Execution, Persistence, Privilege Escalation, Defense Evasion, Credential Access, Discovery, Lateral Movement, Collection, Command & Control, Exfiltration, Impact)
* **Techniques** – The cells (ways to achieve that goal, like Phishing, PowerShell, or Valid Accounts)
* **Sub-techniques** – Specific methods under a broader technique (e.g., under Phishing: Spearphishing Attachment, Spearphishing Link)

Why it’s valuable in investigations:

* **Shared language** – Analysts can say “T1566.001” and everyone knows it means Spearphishing Attachment (well not really, but they can look it up).
* **Threat hunting** – You can map logs and detections to techniques to see which parts of the attack chain you’re catching (and which you’re missing).
* **Adversary emulation** – Red teams use it to replicate the TTPs of specific threat groups.
* **Intelligence linking** – Campaigns can be compared by which techniques they use.

Real-world examples:

* Mapping a ransomware incident: Initial Access (T1566 – Phishing) → Execution (T1059 – Command and Scripting Interpreter) → Impact (T1486 – Data Encrypted for Impact).
* Threat intel reports often cite MITRE IDs so defenders can quickly check their detection coverage.
* Groups like APT29 (Cozy Bear) and FIN7 have their observed behaviors documented in ATT\&CK, helping defenders anticipate future moves.
