Car dealership software-as-a-service provider CDK Global, used by over 15,000 car dealerships in North America, was hit by a massive cyberattack, causing its systems to shut down. The attack, suspected to be ransomware, left clients unable to operate normally, affecting key operations like CRM, financing, and inventory management. Employees at impacted dealerships reported being forced to resort to manual processes, causing widespread disruption. CDK advised dealerships to disconnect from their data centers due to concerns of threat actors accessing internal networks. The incident has raised fears of data theft, encryption, and potential leaks. The company has not provided much information on the attack, sparking speculation that backups may have been impacted as well. It remains unclear how long the outages will last, but CDK is working to resolve the issue with caution.
