Cyberattack Strands Drivers Nationwide by Disabling Breathalyzer Systems

A cyberattack on Intoxalock, a company providing breathalyzer devices for vehicles, has left thousands of drivers across the U.S. unable to start their cars. The attack occurred on March 14, 2026, leading to a nationwide outage affecting users in 46 states, including Maine. Drivers are locked out of their vehicles if they miss required calibrations, and the company has confirmed that it is experiencing significant downtime. Intoxalock has not disclosed the nature of the cyberattack or whether a ransom demand was made. Reports indicate that the attack has impacted installations, removals, and account access for users. The company is working to resolve the issue but has not provided a timeline for recovery. Local auto shops are reporting an influx of vehicles unable to start due to the system failure. The Secretary of State's Office in Maine is aware of the situation and is coordinating with Intoxalock.

Key Points: • Intoxalock's breathalyzer systems are down due to a cyberattack, affecting drivers nationwide. • The attack has resulted in vehicles being locked out if calibration is missed, impacting thousands. • Intoxalock has not confirmed the attack method or if a ransom was demanded.
