A cyberattack on U.S. vehicle breathalyzer company, Intoxalock, has left drivers across the country stranded and unable to start their vehicles. The company, which sells breathalyser devices that can be calibrated for drivers who need to provide a negative alcohol breath sample, was hit by the cyberattack. The cyberattack has left IntoxAlock unable to perform these calibrations, leading to delays in starting cars. It did not specify what type of cyberattack was occurring, nor if there was a data breach or any ransom demands were made.
