Threat Actor Profiling

You cannot defend against everyone — so defend against whoever actually targets you. A threat profile is structured knowledge of an adversary: their motivation, TTPs, tooling and infrastructure. This is the field guide to building one — actor vs campaign vs intrusion set, the Diamond Model, the Kill Chain, MITRE ATT&CK, the Pyramid of Pain, attribution and its traps, the vendor naming chaos (APT28 = Fancy Bear = Forest Blizzard) — and how to turn it into a defence plan for your own org.
