The Children’s Center of Hamden (TCCOH) is providing notice of a recent data security incident that may have involved personal and/or protected health information. TCCOH has sent notice of this incident to potentially affected individuals and provided resources to assist them.  

On December 28, 2024, TCCOH discovered unusual activity within our digital environment, and immediately initiated an investigation of the matter. TCCOH engaged independent cybersecurity experts to assist with the process. As a result of the investigation, TCCOH determined that certain files may have been accessed and acquired without authorization on June 29, 2025.  

TCCOH then undertook a review of those files to determine the individuals whose information could have been involved and the nature of the potentially affected information. That process was completed on August 7, 2025, at which time TCCOH took additional steps in furtherance of providing written notice. Notice of this event was mailed directly to potentially affected individuals with an available mailing address on August 28, 2025.  

Based on its review of the potentially affected data, the following information varied per individual but may have been involved in the incident: Name, date of birth, Social Security number, license or passport information, biometric data and diagnosis or treatment information.  

As soon as they discovered this incident, TCCOH took the steps described above and implemented measures to enhance security and minimize the risk of a similar incident occurring in the future.
