Exfiltration reached
This 2D simulator lays a red-team kill chain flat on a network graph: an attacker starts at an entry workstation and, stage by stage, attempts initial access, privilege escalation, lateral movement across the file server toward the domain controller, then exfiltration to an external drop. Every stage rolls independently for attacker success and defender detection, and the defense posture slider — Patch, Isolate or Monitor — reshapes those odds differently per stage, exactly like real controls shrink an attack surface, block network hops, or add visibility without blocking anything. Launch a single campaign to watch the attack path trace itself across the graph, or run 200 trials to see the empirical breach rate settle out.
