What is the MITRE ATT&CK Framework?

The MITRE ATT&CK Framework (Adversarial Tactics, Techniques, and Common Knowledge) is a comprehensive database that categorizes and describes the tactics and techniques used by cybercriminals and state-sponsored hackers to infiltrate systems and networks. It serves as a detailed playbook for understanding the strategies threat actors use in real-world attacks.

Origins of the Framework

• Development: The MITRE ATT&CK Framework was developed by MITRE Corporation, a nonprofit organization that works closely with the U.S. government on cybersecurity and other technological challenges.
• Purpose: It originated in 2013 as a way to study and categorize cyberattacks based on real-world observations. MITRE analysts reviewed forensic data, threat reports, and cyberattack case studies to understand how attackers operate step-by-step.
• Launch: The framework was first released in 2015, focusing solely on tactics targeting Windows systems.

Growth and Evolution

Since its release, the MITRE ATT&CK Framework has significantly expanded to cover a variety of platforms and environments, including:

• Operating Systems: Windows, Linux, and macOS.
• Cloud Systems: Public, private, and hybrid cloud environments.
• Mobile Devices: Tactics and techniques specific to Android and iOS.
• Industrial Control Systems (ICS): Used in critical infrastructure like power plants and manufacturing facilities.

Real-World Insights

One of the key strengths of ATT&CK is its foundation in real-world data. The framework is built by analyzing actual cyberattacks carried out by known threat groups such as:

• APT28 (Fancy Bear): A Russian state-sponsored hacking group.
• Lazarus Group: A North Korean cybercrime organization.
• FIN7: A financially motivated hacking group.

MITRE collaborated with private companies, government agencies, and cybersecurity firms to reverse-engineer these attacks, documenting tactics such as:

• Reconnaissance
• Initial Access
• Privilege Escalation
• Data Exfiltration

What are Tactics and Techniques in MITRE ATT&CK?

The MITRE ATT&CK Framework dissects cyberattacks into two key components: Tactics and Techniques. Understanding these distinctions is crucial for effective defense.

Tactics: The “Why” Behind the Attack

Think of Tactics as the goals or objectives an attacker wants to achieve during their intrusion. The framework outlines 14 core tactics, each representing a desired outcome in the attack lifecycle. 

For example, some key Tactics defined are:

• Initial Access – How the attacker first gains a foothold in the targeted environment
• Execution – Running malicious code on victim systems
• Persistence – Maintaining access after the initial compromise
• Privilege Escalation – Obtaining higher levels of system permissions
• Defense Evasion – Avoiding or disabling security controls
• Credential Access – Stealing account login details

Techniques: The “How” of the Attack

Techniques, on the other hand, delve deeper into the specific methods attackers use to achieve their tactical goals. Each tactic within the framework has numerous associated techniques, detailing how attackers might exploit vulnerabilities, steal credentials, or establish persistence on a compromised system. 

Some examples of Techniques include:

• Spearphishing Link (Initial Access tactic)
• PowerShell (Execution tactic)
• BIOS Rootkit (Persistence tactic)
• AppCert DLLs (Privilege Escalation tactic)
• Code Signing (Defense Evasion tactic)
• Credential Dumping (Credential Access tactic)

Common Knowledge: Attacker assumptions about defender awareness

While not a core component, CKC plays a supporting role. It refers to the baseline knowledge attackers assume defenders possess. Understanding CKC helps defenders anticipate how attackers might exploit these known factors during an attack. This includes things like:

• Descriptions of operating system components
• Explanations of protocol functionality
• Typical network configurations
• Overviews of common utilities and tools
• High-level definitions of malware characteristics

Data Sources of the MITRE ATT&CK Framework

You might be wondering – how did MITRE get all this juicy insider info on what the bad guys are up to? Well, they’ve got some seriously dedicated researchers over there. The MITRE ATT&CK Framework stands strong as a result of its rich and diverse data sources. Here’s a breakdown of the key contributors: 

• Publicly Available Threat Intelligence: Open-source threat intelligence feeds and research from cybersecurity experts provide valuable insights into attacker tactics.
• Incident Reporting: Real-world incident reports from organizations encountering cyberattacks offer crucial firsthand knowledge of attacker behaviors.
• Security Researcher Contributions: The cybersecurity community plays a vital role. Security analysts and threat hunters contribute their research on new and emerging attack techniques.

The Three Iterations of MITRE ATT&CK

The MITRE ATT&CK Framework isn’t a one-size-fits-all solution. It recognizes the diverse landscapes defenders navigate. Here’s a quick breakdown of its three main iterations:

1. Enterprise ATT&CK: This is the most widely used version, focusing on attacks targeting enterprise networks. It covers the tactics and techniques employed against common operating systems like Windows, macOS, and Linux, along with cloud environments.

2. Mobile ATT&CK: As mobile devices become more integrated into our lives, so do mobile threats. This iteration concentrates on attack vectors specifically designed for Android and iOS platforms.

3. ICS ATT&CK: Industrial Control Systems (ICS) manage critical infrastructure. This specialized version tackles tactics targeting ICS environments, helping defenders secure these vital systems.

What is MITRE ATT&CK Matrix

The MITRE ATT&CK Framework is often visualized as a matrix, offering a comprehensive view of attacker tactics and techniques. This matrix is essentially the master database cataloging all those shady adversary behaviors and tactics. It’s laid out in a big grid, with the tactical objectives like initial access and persistence running across the top, and all the specific techniques mapped out underneath.

So for example, under the “Initial Access” tactic column, you’ll find a list of entry vectors like drive-by compromises, exploits, valid account abuse, and hardware additions. Each technique has its own entry describing exactly how attackers use that method.

The matrix also cross-references each technique against the pieces of software, protocols, and system utilities from the “Common Knowledge” base that adversaries are known to abuse or misuse while carrying out those tactics.

But it gets even more comprehensive. The ATT&CK team doesn’t just document the dry technical details. They actually provide a ton of context around each technique:

• Which specific threat groups are known to use it
• The remote access tools or malware families involved
• Mitigations and detections to look out for
• Real-world examples and case studies of that technique in action

It’s like having the ultimate encyclopedia or field manual for defending against cyber attacks. The level of detail is crazy! The official MITRE ATT&CK website provides a searchable matrix. You can filter by tactics, techniques, platforms, and data sources.
