Cyberattack Disrupts Operations at 15,000 U.S. Car Dealerships, CDK Global Systems Temporarily Shut Down

CDK Global, a leading provider of automotive dealership software in the U.S., has experienced a cyberattack that led to the shutdown of most of its systems, disrupting sales at about 15,000 car dealerships.


Notable clients impacted include General Motors dealerships, Group 1 Automotive, and Holman, which operates across eight states.


A spokesperson from CDK said, "We are currently addressing a cyber incident. To ensure the safety of our customers, we've temporarily disabled most of our systems and are striving to restore them as swiftly as possible."


By Wednesday afternoon, CDK announced that certain systems were back online after thorough tests and consultations with cybersecurity experts.


"Our primary dealer management system and Digital Retailing solutions are operational again. We are rigorously testing all other applications and will continue to update as we reactivate them," CDK reported to CBS MoneyWatch.


The dealer management system (DMS) from CDK is essential for overseeing all dealership activities through a unified interface, and its retail tools support transactions both online and in the showroom.


On its website, CDK boasts of a robust cybersecurity approach with a three-tier strategy focused on preventing, defending against, and responding to cyber threats to safeguard dealership operations.


The cyberattack, which began Tuesday evening, was first reported by Bleeping Computer, a cybersecurity news outlet. It affected CDK's ability to service the 15,000 dealerships dependent on its systems.


The attackers' identities have yet to be determined.


Following the incident, some dealerships have turned to manual operations. According to discussions on Reddit, employees are using spreadsheets and sticky notes for handling minor sales and repairs, although major transactions are severely affected.


One employee asked, "How many of you are standing around because your whole shop runs on CDK?" with users from dealerships in Wisconsin and Colorado confirming their systems were down.
