Once you know what you are looking for, gather the necessary telemetry. This involves querying your SIEM, central log repositories, or Endpoint Detection and Response (EDR) tools. You filter out the baseline noise to isolate outliers. 3. Investigation and Triage
Forcing an attacker to abandon a preferred tool (like Mimikatz or Cobalt Strike) and build or learn a new one creates significant friction.

OpenCTI and MISP (Malware Information Sharing Platform) allow teams to store, organize, and correlate threat intelligence feeds automatically. Conclusion and Next Steps
Successful data-driven hunting relies on structured mental models to track and categorize attacker behavior.
What (e.g., Splunk, Microsoft Sentinel, Elastic) does your organization currently use? Once you know what you are looking for,
Intelligence enables defenders to understand the tactics, techniques, and procedures (TTPs) of specific adversaries.
A successful hunt begins with a hypothesis—a prediction about how an attacker might operate.
