A major cyberattack has hit CDK Global, a company that provides software to car dealerships across North America, causing widespread disruptions to car sales.
The attack forced CDK to shut down its systems, preventing car dealers from processing transactions like sales and financing.
It's believed that the attack involved ransomware, a type of malicious software that encrypts data and demands payment for its release.
While some systems are back online, the incident has highlighted the vulnerability of critical infrastructure to cyberattacks and the importance of cybersecurity.
