The "Pyramid of Pain" is an essential concept in the field of cybersecurity, particularly within the context of threat hunting and incident response. It is a model that helps security professionals understand the varying levels of difficulty in detecting adversary tactics, techniques, and procedures (TTPs). The TryHackMe platform offers a hands-on learning experience centering around this concept, providing users with a structured walkthrough to enhance their skills in recognizing and mitigating threats. This article will guide you through the Pyramid of Pain as implemented in TryHackMe, detailing its components, the learning experience, and practical applications.
The Pyramid of Pain Explained
The Pyramid of Pain, conceptualized by David J. Bianco, visualizes the relationship between the difficulty of detecting certain indicators of compromise (IoCs) and the potential impact on an organization’s security posture. It categorizes various types of IoCs into a pyramid structure:
1. Hash Values
2. IP Addresses
3. Domain Names
4. URLs
5. Tactics, Techniques, and Procedures (TTPs)
Each layer of the pyramid represents a different level of pain or challenge associated with detection and response. As you move up the pyramid, the IoCs become more abstract and harder to detect, making them more valuable for defenders to focus on.
- Description: Hash values are unique identifiers generated from files using cryptographic algorithms. They are the easiest and most precise indicators to detect.
- Challenge Level: Low. Security systems can easily identify files based on their hash values.
- Use Case: If a known malware file is detected via its hash, immediate action can be taken to quarantine or remove it.
- Description: IP addresses point to specific machines on the internet. Monitoring network traffic for known malicious IP addresses can help in identifying threats.
- Challenge Level: Low to Moderate. While detecting connections to known bad IPs is straightforward, attackers can easily change their IP addresses.
- Use Case: Blocking or monitoring traffic from suspicious IP addresses can prevent further compromise.
- Description: Domain names are often used by attackers to hide their infrastructure. Detecting malicious domains requires more sophisticated monitoring tools than IP addresses.
- Challenge Level: Moderate. Domain names can be registered and changed frequently, making detection more challenging.
- Use Case: Implementing threat intelligence feeds to block access to known malicious domains can bolster security.
- Description: URLs represent specific resources on the web. Analyzing URLs can reveal phishing attempts or drive-by downloads.
- Challenge Level: Moderate to High. URLs can be obfuscated, and attackers often use legitimate services to host malicious content.
- Use Case: Utilizing URL filtering and analysis tools can help prevent access to harmful sites.
- Description: TTPs describe the behavior and modus operandi of attackers. This layer focuses on understanding the threat actor’s strategies rather than just their tools.
- Challenge Level: High. TTPs require deep analysis and understanding of the attacker's behavior and intentions.
- Use Case: Threat hunting methodologies and behavioral analysis can help organizations prepare for and mitigate sophisticated attacks.

Frequently Asked Questions
What is the Pyramid of Pain in cybersecurity?
The Pyramid of Pain is a model that illustrates the various levels of difficulty an adversary faces when trying to evade detection by security measures. It categorizes indicators of compromise (IOCs) from easy-to-evade attributes like IP addresses to more difficult ones like tactics, techniques, and procedures (TTPs).
How does the Pyramid of Pain relate to threat hunting?
The Pyramid of Pain provides a framework for threat hunters to prioritize their efforts. By focusing on higher levels of the pyramid, such as TTPs, threat hunters can develop a deeper understanding of attacker behavior and improve detection strategies.
What are some key indicators of compromise at the top of the Pyramid of Pain?
At the top of the Pyramid of Pain, key indicators include TTPs, such as specific techniques used by attackers during an intrusion. These are harder for attackers to change, making them more valuable for security teams to monitor.
What are practical steps to implement the Pyramid of Pain in a cybersecurity strategy?
To implement the Pyramid of Pain, organizations can start by identifying and prioritizing IOCs at different levels, focusing on TTPs for detection and prevention strategies, enhancing threat intelligence capabilities, and integrating these insights into security tools and processes.
What is a common mistake organizations make regarding the Pyramid of Pain?
A common mistake is over-relying on low-level IOCs, such as IP addresses or file hashes, which are easier for attackers to change. Instead, organizations should focus on higher-level indicators, like TTPs, for more effective long-term defense.
Can the Pyramid of Pain be applied to incident response?
Yes, the Pyramid of Pain can enhance incident response by helping teams identify the most relevant TTPs during an investigation, allowing them to understand the attacker's methods and improve response strategies based on the insights gathered.
What role does threat intelligence play in the Pyramid of Pain framework?
Threat intelligence is crucial in the Pyramid of Pain framework as it provides insights into the TTPs used by adversaries. This information helps organizations stay ahead of threats by adapting their security measures and detection capabilities accordingly.
