Last week, hackers launched a cyberattack on an Iowa company called Intoxalock that left some drivers unable to start their court-mandated breathalyzer-equipped cars. Wired reports: Intoxalock, an automotive breathalyzer maker that says it's used daily by 150,000 drivers across the U.S., last week reported that it had been the target of a cyberattack, resulting in its "systems currently experiencing downtime," according to an announcement posted to its website. Meanwhile, drivers that use the breathalyzers have reported being stranded due to the devices' inability to connect to the company's services. "Our vehicles are giant paperweights right now through no fault of ours," one wrote on Reddit. "I'm being held accountable at work and feel completely helpless." The lockouts appear to be the result of Intoxalock's breathalyzers needing periodic calibrations that require a connection to the company's servers. Drivers who are due for a calibration and can't perform one due to the company's downtime have been stuck, though the company now states on its website that it's offering 10-day extensions on those calibrations due to its cybersecurity disruption, as well as towing services in some cases. In the meantime, Intoxalock hasn't explained what sort of cyberattack it's facing or whether hackers have obtained any of the company's user data.Read more of this story at Slashdot.
