Cyberattack Disrupts Intoxalock Breathalyzer Services for Drivers

Intoxalock, a company that manufactures ignition interlock devices used by approximately 150,000 drivers in the United States, reported a cyberattack that has severely impacted its services. The incident, which began on March 14, 2026, has left many drivers unable to start their vehicles due to the devices' inability to connect to the company's servers for necessary recalibrations. As a result, some users have expressed frustration, describing their vehicles as "giant paperweights" and feeling helpless in their situations.

The cyberattack has particularly affected drivers in Connecticut, where an estimated 6,000 customers rely on Intoxalock devices to comply with court-mandated alcohol monitoring. These devices require regular recalibration every 25 to 30 days to ensure proper functionality. Due to the disruption, Intoxalock has offered a 10-day extension for required calibrations and has provided towing services for vehicles that cannot start. The company has stated that while the devices themselves remain operational, the inability to perform recalibrations has left many drivers stranded.

Intoxalock has clarified that the disruption was a precautionary measure in response to a cyber threat, rather than a direct attack on their systems. Rachael Larson, a spokesperson for Intoxalock, emphasized the company's commitment to supporting affected customers and stated, "We are sorry for the inconvenience this has caused and are working diligently to resume our systems." The company has also established a dedicated texting line for customer inquiries and is covering costs related to the disruption.

The incident at Intoxalock is part of a larger trend of increasing cyberattacks targeting critical infrastructure and services. Experts note that such attacks are often motivated by financial gain or ideological aims. In 2024, losses from cybercrime in the United States exceeded $16 billion, highlighting the growing threat to businesses and individuals alike. Evan Allard, director of the Connecticut Intelligence Center, pointed out that many attackers exploit basic cybersecurity vulnerabilities, underscoring the need for improved protective measures.

While Intoxalock has taken steps to mitigate the impact of the disruption, some critics have raised concerns about the company's preparedness for such incidents. The reliance on technology for compliance with legal requirements places significant pressure on both the company and its customers. As the situation unfolds, the effectiveness of Intoxalock's response will be closely monitored by both users and regulatory bodies.
