On a busy holiday Wednesday, thousands of car dealerships in the US experienced operational disruptions due to a cyber incident at CDK Global, a leading software provider. The outage affected CDK’s dealer management systems and digital retailing solutions, leading many dealerships to either shut down or revert to manual processes for routine operations. CDK responded by shutting down all systems for testing and consultation with third-party experts. Dealers expressed concern over protecting customer information and sought details from CDK about the incident.
