A company that makes ignition interlock devices said Sunday it has resumed normal operations after a cyberattack disrupted some services for hundreds of customers in Connecticut and elsewhere around the country.
Intoxalock, the Iowa company that was targeted, was temporarily unable to complete calibrations on its devices — a maintenance process some drivers in Connecticut must complete every 25 to 30 days in order to keep using their cars.
Ignition interlock devices stop people who are intoxicated from turning on their vehicles. Drivers blow into them at random times to ensure they aren't under the influence. The devices also require regular recalibration at a service center to keep functioning.
The company previously said it paused some of its systems as a precaution after it experienced what it called a "cyber event" on March 14.
The unexpected disruption left some customers around the country who were due for a calibration unable to start their cars. In Massachusetts, WCVB reported vehicles were left idle for days at one business.
In Connecticut, people who receive license suspensions for offenses including drunk driving and refusing an alcohol test must install ignition interlock devices in order to have their licenses reinstated, according to the state Department of Motor Vehicles.
Intoxalock said it serves an estimated 6,000 customers in the state. Responding Saturday to questions from Connecticut Public, the company said it believes 7-10% would have required a calibration in the time since its systems were disrupted.
The company said it established a process on March 18 for affected customers to receive a 10-day extension for calibrations. In a message posted to its website early Sunday evening, the company said its systems have resumed and installations, calibrations and service center support are now available.
The company advised customers who received an extension during the outage to return to a service center for a calibration before the 10-day window expires. Others who required but didn't receive a calibration may need to have their vehicles taken to a service center, the company said.
Intoxalock previously set up a designated texting line at 424-724-4689. The company said it will cover costs that are a direct result of the temporary system pause.
"We are sorry for the inconvenience this has caused and are working diligently to resume our systems, and are fully committed to supporting our customers throughout this process," spokesperson Rachael Larson said in a statement.
Intelligence experts say cyberattacks targeting critical systems and infrastructure are on the rise, with hackers motivated by financial gain, as well as geopolitical and ideological aims.
Nationwide, losses from cyber crime topped $16 billion in 2024, up by a third from the year before, according to the most recent assessment by the FBI.
In one recent example, medical device maker Stryker Corporation acknowledged this month its systems were disrupted by a cyberattack, though the company said none of its products were impacted.
Locally, officials in New Britain disclosed in January the community was targeted by a ransomware attack.
Evan Allard, director of the Connecticut Intelligence Center, a law enforcement partnership that gathers information related to threats, said hackers are increasingly targeting lifeline sectors and organizations with sensitive data, such as health care and telecommunications companies.
Allard said in Connecticut, state and federal partners have an integrated response plan to assist public and private entities that are targeted to restore their systems as quickly as possible.
However, prevention is just as important, Allard said. Many attackers gain access through social engineering rather than more sophisticated techniques, he said.
"It comes down to basic cybersecurity practices for a lot of these type of attacks," he said.
