Defines threat hunting as human-driven, proactive, iterative work and gives a starter program: choose unstructured ad hoc hunts or a structured, ticketed team; focus detections above simple hashes on the upper half of the pyramid of pain (network/host artifacts and TTPs); follow four phases — pre-hunt • hunt • post-hunt • reporting — with documented hypotheses, gap analysis, lessons learned, and content handoff to SIG/SOC teams. Recommends central log storage, EDR/SIEM data, a ticket system, chat, a maturity matrix (people/process/tech), and that one curious person doing hours daily is worthwhile.
