Using MITRE ATT&CK as an analysis tool

// Rethinking MITRE ATT&CK

When working in security, you’re likely familiar with the MITRE ATT&CK framework. It’s often treated like a bingo card, with boxes checked off as tools and techniques are deployed or discovered. But to truly leverage its potential, consider using it as an analytical framework instead, focusing on understanding incident patterns and behaviors rather than simply ticking off techniques.

// Scenario Overview

Imagine you’ve been tasked with investigating suspicious activity on a server in your environment. The logs show multiple failed SSH login attempts followed by a successful login from an unfamiliar IP address. Instead of immediately jumping to conclusions, use the ATT&CK framework to guide your analysis.

// Step-by-Step Analysis Workflow

1. Initial Log Review Start with a review of the relevant logs. Use grep to filter for SSH access:

   grep 'sshd' /var/log/auth.log

Look for entries indicating successful and failed login attempts.

2. Identify Techniques Based on the log entries, identify techniques from the ATT&CK framework. For example, failed SSH attempts could indicate the use of brute force attacks (T1110). Cross-reference it with your logs to identify patterns.

3. Examine User Behavior Investigate the user behavior associated with the successful login.

   last -i | grep 'username'

This will show logins for a specific user along with their associated IP address.

4. Correlate with Other Data Sources Enhance your investigation with data from other logs, such as firewall logs to see if the unfamiliar IP has been flagged:

   cat /var/log/iptables.log | grep 'unfamiliar_ip'

Look for any previous interactions or blocked attempts.

5. Contextual Analysis Using ATT&CK, determine if the activity aligns with known adversary behaviors. For example, T1078 (Valid Accounts) could be relevant if valid credentials were used.

// Mistakes to Avoid

  • Overlooking Context: It’s easy to get caught up in the techniques. Always consider the broader context of the actions taking place.
  • Focusing on Tools Instead of Goals: Don’t just identify tools; focus on what the attacker aims to achieve with those tools.

// Defensive Implications

Understanding the attack vectors and techniques helps inform your defensive posture. For instance, implementing rate-limiting on SSH connections can mitigate brute force attempts. Additionally, consider deploying an intrusion detection system (IDS) that can monitor for suspicious login patterns.

// Checklist for Effective Analysis

  • [ ] Collect relevant log data from multiple sources.
  • [ ] Identify techniques used in your logs using the ATT&CK framework.
  • [ ] Analyze user behavior and correlate with other data.
  • [ ] Assess the intent behind the observed behaviors.
  • [ ] Recommend or implement defensive measures based on your findings.

// Conclusion

By shifting your perspective on MITRE ATT&CK from a checklist to a comprehensive analytical tool, you can deepen your understanding of threats and improve your incident response capabilities. Remember, the tactics, techniques, and procedures (TTPs) are not just boxes to check but insights into adversarial behavior.

Explore these techniques in a controlled manner within a lab or an environment you own. The DaemonCore Academy curriculum is free, and you can practice these methodologies in a disposable range for thorough understanding.
