CDK Global (2024)

On June 18, 2024, CDK Global — the dealer-management-system provider for ~15,000 North American auto dealerships — was attacked by BlackSuit ransomware. A second attack on June 19 disrupted recovery efforts. Most dealerships reverted to paper processes for two weeks. Anderson Economic Group estimated total dealer losses at $1.02B; CDK reportedly paid ~$25M in ransom. The incident is a benchmark for indirect cascade damage from sector-concentrated SaaS compromise.
