Scrimmage

Red-team actions vs. blue-team response on one clock — under fog of war. Blue only acts on what its logging has detected, so quiet moves slip through. Watch the gap between what blue believes is contained and what actually is.

Timeline

Red Blue System
No actions yet. Launch a red move or load a scenario to start the clock.
Fog-of-war build. Each red technique has a noise level and a detection threshold; it's spotted only if blue's logging is high enough at the moment it runs. Quiet, valid-credential moves (lateral movement, DC pivot) evade medium logging and stay invisible. Blue acts on its own picture: Isolate all compromised and Reset exposed credentials only touch what's been detected, and Threat hunt is how you reveal the rest. Posture is computed on ground truth; the believed line shows what blue would conclude from its visibility alone. Durations are illustrative — tune them to your environment.
