Daniel H. Cook Associates, Inc. (DHCA) has disclosed a data breach affecting more than 36,000 individuals. The breach, involving a hacking incident, potentially exposed names and Social Security numbers of impacted individuals.

Daniel H. Cook Associates’ Data Breach Investigation

Daniel H. Cook Associates, Inc. (“DHCA”), a provider of healthcare-related administrative services, recently confirmed a data security breach stemming from an unauthorized system intrusion. The incident occurred on October 17, 2025, and was discovered following unusual network activity. DHCA responded by engaging leading cybersecurity experts and launching a full-scale investigation to understand the scope of the breach.

According to the investigation, external actors accessed and potentially acquired sensitive files from DHCA’s internal systems. A thorough review concluded that some of these files contained personal information, prompting DHCA to issue notifications to affected individuals in January 2026.

The exposed information includes highly sensitive data, most notably names in combination with Social Security numbers—data that could be used to commit identity theft. Although DHCA stated there is no current evidence of misuse, the company is offering 24 months of free identity protection services through IDX. These services include credit monitoring, dark web surveillance, a $1 million identity fraud insurance policy, and full identity recovery assistance.

This breach underscores the risks consumers face when their sensitive information is stored by third-party service providers. Even without evidence of misuse, the exposure of Social Security numbers represents a significant risk. Consumers deserve transparency and the opportunity to hold negligent organizations accountable when their data is compromised.
