At Console & Associates, our data breach lawyers are closely examining the recent College Hospital Costa Mesa data breach. This data breach was disclosed following a cyber security incident at College Hospital Costa Mesa, which potentially exposed sensitive personal identifiable information including names, Social Security numbers, and driver's license numbers of affected individuals.

What Happened?

A recent report from the California Attorney General's Office states that the College Hospital Costa Mesa data breach occurred due to a cyber security incident. According to the investigation, the hospital experienced a network disruption on September 17, 2024, that affected multiple computer systems within their network infrastructure.

Following the discovery of suspicious activity, College Hospital Costa Mesa implemented security measures to protect their systems, contacted law enforcement authorities, and engaged specialized cybersecurity experts to conduct a thorough investigation of the incident.

The investigation revealed that an unauthorized third party had gained access to specific files and folders on the hospital's IT network during a period spanning approximately one month—from August 14, 2024, to September 17, 2024. During this time, the unauthorized party was able to access confidential information stored within the hospital's systems.

After confirming the security breach, College Hospital Costa Mesa conducted an extensive review of all potentially affected files to determine exactly what information had been compromised and which individuals were impacted. This comprehensive analysis was completed on January 31, 2025. The sensitive personal data that may have been exposed includes:

• Full names
• Social Security numbers
• Driver's license numbers

Data breach notification letters were sent out by College Hospital Costa Mesa on March 10, 2025, informing affected individuals about the nature of the incident and what specific types of their personal information may have been compromised in the breach.
