What is Threat Hunting?
Threat hunting is the proactive search through networks and datasets to detect threats that evade traditional security solutions. Unlike reactive approaches, threat hunting assumes adversaries are already present.
Why Hunt?
70% of breaches are discovered by external parties. Proactive hunting finds threats before attackers achieve their objectives.
Threat Hunting Process
Hunting Methodology
Hypothesis
Develop hunting theory
Collect
Gather relevant data
Analyze
Search for indicators
Detect
Create new detections
Hypothesis-Driven Hunting
- Start with a hypothesis based on threat intel or known TTPs
- Define data sources needed to test the hypothesis
- Execute searches and analyze results
- Create detections from findings
Hunting Maturity Model
Maturity Progression
Level 1: Initial
Primarily reactive, rely on automated alerts, no dedicated hunting capability
Level 2: Procedural
Defined hunting processes, regular cadence, threat intel integration
Level 3: Innovative
Data-driven hypothesis, custom detections, advanced analytics
Level 4: Leading
Automated workflows, ML integration, original research

MITRE ATT&CK Integration
Use MITRE ATT&CK as your hunting guide. Map hunts to techniques, track coverage, and prioritize based on adversary behavior.
Conclusion
Threat hunting transforms security from reactive to proactive. By actively searching for threats, organizations significantly reduce dwell time and limit breach impact.
