MITRE ATT&CK Framework: A Guide to Understanding How Hackers Attack
The MITRE ATT&CK framework represents a comprehensive, globally recognised knowledge base designed to assess the various tactics, techniques, and procedures that adversaries employ throughout the stages of a cyberattack. Developed by MITRE in 2013, this resource has become indispensable for cybersecurity professionals, enabling them to bolster their defence strategies by enhancing threat detection, incident response, and overall vulnerability management.
The acronym ATT&CK stands for Adversarial Tactics, Techniques, and Common Knowledge. The framework is organized into a matrix that categorizes different cyberattack techniques based on the adversarial tactics they align with. Furthermore, there are separate matrices for different operating systems, including Windows, Linux, Mac, and mobile platforms.
Incorporating the ATT&CK framework into an organisation’s security practices significantly enhances its ability to identify, understand, and mitigate adversarial tactics, ultimately strengthening the overall resilience of its cyber infrastructure.
Let’s understand the MITRE ATT&CK framework in detail.
ATT&CK Matrix
The MITRE ATT&CK Framework breaks down attack behaviour into a matrix of tactics (the goals of an attack), techniques (the methods used to achieve those goals), and sub-techniques (more detailed breakdowns of how a technique might be executed). This structure offers a comprehensive view of how an attack can unfold, helping security teams understand the steps adversaries take during an attack.
Tactics: The “Why” of an Attack
At the core of the MITRE ATT&CK Framework are the tactics. These represent the high-level goals that an attacker aims to achieve at each stage of the attack. Tactics are organised into different stages such as Initial Access (getting into the system), Execution (running malicious code), and Exfiltration (stealing data).
Techniques: The “How” of an Attack
Under each tactic, there are various techniques that describe the specific methods adversaries use to achieve their objectives. For example, under the Initial Access tactic, techniques could include spear phishing or exploiting public-facing applications. These techniques give organisations insight into the tools and strategies hackers are likely to use to break into systems.
Sub-techniques: A Closer Look
Some techniques have sub-techniques, providing even more granular details on how an attack is carried out. For instance, under spear phishing, attackers might use spear phishing via attachment or spear phishing via link to deliver malicious payloads.
Detection and Mitigation
In addition to tactics and techniques, the framework offers recommendations on mitigation and detection. These guidelines help security teams identify where their defences may be lacking and take action to prevent or quickly detect certain techniques, such as monitoring for unusual PowerShell commands or blocking known malicious IP addresses.
Use cases of MITRE ATT&CK Framework in Your Security Operations
The MITRE ATT&CK Framework offers organisations a structured way to improve their security posture. Let’s explore some key strategies for utilising this valuable resource.
Identify Security Loopholes
MITRE ATT&CK Framework is a critical tool for evaluating the effectiveness of your existing security infrastructure. By evaluating your security infrastructure against known tactics, techniques, and procedures, you can identify gaps and vulnerabilities within your system. This process allows you to pinpoint weaknesses that may not be immediately apparent
through traditional assessment methods. Consequently, you can prioritise improvements based on your organisation’s industry, risk appetite, and tolerance.
Threat Intelligence Collection
MITRE ATT&CK Framework also serve as an invaluable tool for gathering threat intelligence. By mapping specific threat actors and associated malware families to the ATT&CK matrix, organisations can maintain a detailed, up-to-date profile of adversary behaviour. Additionally, the framework provides a standardized approach for describing and categorizing attack behaviours. This eliminates the need for custom terminology and ensures clear communication and analysis of threats.
Hunt for Threats
The MITRE ATT&CK Framework is a key resource for threat-hunting activities. It provides a detailed repository of adversary behaviours that security teams can use to guide their operations. The framework helps formulate hypotheses, prioritize threats, collect data, and consistently document findings. By focusing on techniques seen in past attacks, ATT&CK allows hunters to search for indicators of compromise (IOCs) within their networks, improving proactive detection and response.
Research
The MITRE ATT&CK framework helps security researchers standardize adversary behaviors. It’s detailed and structured nature allows researchers to classify and document TTPs (tactics, techniques, and procedures) with precision. This consistency not only streamlines knowledge sharing across the cybersecurity community but also ensures that different research teams are aligned in their understanding of attack methodologies.
Conclusion
The increasing prevalence of cyber threats poses ongoing challenges for organisations. Understanding how hackers operate is crucial for building robust defences. The MITRE ATT&CK Framework provides a structured, detailed method for understanding adversary tactics, techniques, and procedures, making it an essential tool for cybersecurity professionals. By utilising the ATT&CK Matrix, security teams can enhance detection capabilities, respond to incidents more effectively, and proactively hunt for emerging threats.
