Cyberattack Causes Car Dealer System Shutdowns

The dealer management system giant reported that it shut down most of its systems to contain the issue while working to address the problem and restore service. 

On June 19th, 2024, CDK Global, the leading provider of dealership management systems (DMS) in the U.S., suffered a major cyberattack, causing a nationwide shutdown of its systems. CDK Global supports almost 15,000 dealership locations, including GM brands. The timeline for restoring service remains uncertain.

GM Authority notes: According to a report from Automotive News, Tony Macrito, CDK Global’s senior director of communications, stated that the shutdown was a precautionary measure aimed at protecting customers and allowing for a thorough investigation.

The cyberattack was initially communicated to dealerships around 2 a.m. Eastern time, followed by a detailed update at 8 a.m. confirming the incident and explaining the shutdown. The alert was also sent to all dealerships subscribed to CDK’s critical alerts system.

The alert reads as follows: “Dear Valued Customers, we are currently experiencing a cyber incident. Out of caution and concern for our customers, we have shut down a majority of our systems. We are currently assessing the overall impact and currently have no ETA. Please know our teams are working hard to get everything up and running, and we will update as information is available. Sincerely, CDK Customer Care”

A GM Authority source familiar with security incidents stated, “Generally, the longer it takes to identify the scope of the cyber incident, the worse it is”. It has been roughly eight hours since the documented discovery of the incident.”

However, in our opinion, the more important lesson is how it affected all their dealers and systems.
