Autonomous-Vehicle Cyber-Physical Sabotage — Brake/Steering/Sensor Subversion Command

ATR detection rule by ATR Community · MIT

Detects an instruction directing an agent with vehicle-control tools to sabotage a safety-critical autonomous-vehicle subsystem, producing a cyber-physical hazard. Drawn from the AgentSecurityBench (ASB) autonomous-driving domain, these commands pair a destructive verb (compromise / corrupt / disrupt / jam / intercept-and-modify / manipulate / seize / hijack / engineer-false / deploy- false / forge-and-deploy) with a vehicle safety subsystem (braking system, control systems, path-planning, lidar sensors, GPS data, camera feeds, vehicle-to-everything / V2X communications, collision warnings, traffic-sign signals) and almost always a concrete vehicle identifier (vehicle ID Vxxxxxxxx) or autonomous-vehicle reference. The intent is to induce mechanical failure, navigation error, sensing degradation, or remote takeover during operation. This is excessive-agency of the most consequential kind: the agent's actuator/control capability is weaponized to harm a moving vehicle. The rule anchors on the verb+subsystem adjacency so generic "monitor / validate / ensure the braking system" maintenance language does NOT fire.

    [ATR-2026-01801] CRITICAL: autonomous-vehicle cyber-physical sabotage command
    detected. The input directs the agent to compromise, corrupt, jam, hijack, or
    inject false signals into a safety-critical vehicle subsystem (brakes,
    steering/control, lidar, GPS, camera, V2X, collision warning). This can cause
    physical harm. Do NOT execute — block the actuation and report the command.

This submission is arbitrary [[ currentRule.format ? currentRule.format.toUpperCase() : '' ]] code, not a declarative detection rule — review it as you would any script before running it, and note that it cannot be safely aggregated or auto-executed alongside YARA/Sigma/Suricata/CRS rules.
