Explainer: The CDK Global Ransomware Attack

CDK Global, a leading software vendor, provides critical applications and services to nearly 15,000 automotive dealer locations across North America. Founded in 2014 as an independent entity from ADP Dealer Services, CDK Global’s software supports daily operations at automotive dealerships, including vehicle sales, financing, insurance, and repairs.

How the Attack Happened

The ransomware attack on CDK Global occurred on June 18, 2024, disrupting the operations of numerous U.S. auto dealerships. Although specific details of the attack remain undisclosed, it is confirmed that CDK Global fell victim to a ransomware campaign. Common methods for such attacks include phishing schemes to obtain administrative credentials or exploiting software vulnerabilities.

The attack, attributed to the BlackSuit ransomware gang, led to the encryption of critical files and systems, forcing CDK Global to shut down its IT systems. This gang is known for double extortion tactics, demanding ransoms while threatening to release sensitive data.
