Harbor Developmental Disabilities Foundation (d/b/a Harbor Regional Center) data breach

Clerk's notes

Harbor Developmental Disabilities Foundation, known as Harbor Regional Center, officially disclosed a data security incident on May 28, 2026. This California-based organization, which provides critical support and services for individuals with developmental disabilities, confirmed that unauthorized access to its digital systems had occurred. The incident was initially identified on March 6, 2026, and is currently under investigation and monitoring.

The compromised data categories are extensive and highly personal. They include Full Name, Date of Birth, Social Security Number, Medical Record Number, Diagnosis and Treatment Information, Health Insurance Policy Details, Address and Contact Information, and Service Coordination and Regional Center File Data. This array of information is fundamental to client care and case management at a regional center.

Such a breach involving sensitive developmental and health records carries profound risks beyond typical financial fraud. The exposure of these specific data types can lead to long-term medical identity theft, fraudulent attempts to access government assistance programs, and sophisticated phishing schemes tailored to an individual's specific circumstances. Affected individuals may face persistent privacy concerns and increased vulnerability to targeted scams.

If you have received an official data breach notification letter from Harbor Regional Center, it serves as formal confirmation that your personal and sensitive information was exposed. It is advisable to carefully review the specific details provided in your notification. We are currently evaluating this data security incident and offer free, no-obligation case reviews for those potentially impacted by this breach.
