Watsonville Community Hospital’s Data Breach Investigation

Watsonville Community Hospital, a key healthcare provider in Santa Cruz County, California, reported that it detected suspicious activity on its computer systems on November 29, 2024. In response, WCH promptly disconnected portions of its network, isolated the affected systems, and initiated an investigation with cybersecurity experts to determine the nature and scope of the event.

The investigation revealed that an unauthorized third party gained access to a limited subset of WCH’s network between November 25, 2024, and November 30, 2024. During this period, certain files were accessed or downloaded without authorization. Following this discovery, WCH began the process of identifying which individuals were affected and what information was exposed.

A third-party forensic review was completed on or about September 22, 2025, and was followed by an extensive internal review to match affected data with current contact information for notification purposes. WCH subsequently began notifying impacted individuals through mailed letters, public postings, and media announcements starting in October 2025.

The hospital has also reported this incident to the Federal Bureau of Investigation (FBI) and relevant state and federal data privacy regulators. As part of its remediation efforts, WCH reviewed and enhanced its cybersecurity measures, implemented stronger safeguards, and upgraded network defenses to prevent similar incidents in the future.
