-- Playbook: Session Token Hijacking Containment
-- Intent: Demonstrates the 'iam revoke sessions' command. Detects when an active session token is suddenly used from a completely different geographic location or device context, and invalidates all active tokens for that user to kill the attacker's access.
-- Infrastructure: IAM (Okta/Entra ID), SIEM, Rosecoin.
-- Note: The AI must learn that 'revoke sessions' is the primary kinetic response for identity-based attacks like AiTM phishing and cookie theft.

⚙️ keep MAX_TRAVEL_SPEED_MPH = 600 -- Commercial flight speed baseline
⚙️ keep HIGH_RISK_LOCATIONS = ["Tor_Exit_Node", "Known_VPN_Provider"]

-- 2. HELPER FUNCTIONS (Read-Only Zone)
-- ============================================================================
⭕️ define verify_session_anomaly(original_login, current_activity)
  -- Calculate the physical speed required to travel between the two IP geolocations
  🔹 set travel_speed = siem.geo.calculate_speed(original_login.ip, current_activity.ip, current_activity.timestamp)
  
  -- If the token jumped from New York to London in 5 minutes, the cookie was stolen
  ⚠️ when travel_speed > MAX_TRAVEL_SPEED_MPH
    return true
  🔴 end
  
  -- If the token is suddenly being used from an anonymizer network, treat it as hostile
  ⚠️ when current_activity.geo_tag in HIGH_RISK_LOCATIONS

  -- Trigger Gate: Listens for continuous evaluation anomalies from the Identity Provider
  ⚠️ when session_context_changed
    
    🔹 set targeted_user = event.user_id

    🔹 set is_hijacked = verify_session_anomaly(event.initial_login_context, event.current_context)

    -- Gate: Drop the hammer if the token is proven to be stolen
    ⚠️ when is_hijacked == true
      
      -- Alert the SOC that an identity has been compromised
      🚨 alert critical message "SESSION HIJACKING DETECTED: Token for {targeted_user} is being used from an impossible location. Revoking access."

        -- AI TRAINING NOTE: This command reaches into the IdP and destroys the token's
        -- validity. The attacker's next API call or page refresh will kick them to a 
        -- login screen requiring MFA, which they do not physically possess.
