    Ransomware attack and extended service outage

    A ransomware attack beginning June 19 took most CDK services offline and disrupted dealership operations across the United States and Canada. Reports linked the attack claim to a group believed to be BlackSuit. CDK undertook a staged restoration, while affected dealerships reported operational and financial losses and filed lawsuits alleging negligence.
