A cyberattack on Intoxalock, a major provider of court-mandated ignition interlock devices for DUI offenders, caused a nationwide service outage that prevented users from starting their vehicles. The disruption highlights the critical security risks and real-world consequences when essential automotive safety systems rely on vulnerable backend infrastructure. The incident raises serious questions about the resilience of connected devices that control physical access to transportation.
Background
Ignition interlock devices are breathalyzer systems installed in vehicles of individuals convicted of DUI offenses, mandated by courts to prevent drunk driving by requiring a sober breath sample to start the car. These devices are typically connected to backend systems for monitoring, calibration, and compliance reporting.
