Serviceaide, Inc. provides IT support management software to health organizations, including Catholic Health in Buffalo, New York. In May 2025 it reported to the U.S. Department of Health and Human Services that a database holding patient information had been publicly available on the internet.
What happened
Serviceaide says it discovered on November 15, 2024 that data in a database it managed for Catholic Health could be reached without a login. The investigation found the database was exposed from about September 19 to November 5, 2024. Notification letters are dated May 5, 2025, and the breach was filed with HHS on May 9, 2025. It lists 483,126 people.
What was exposed
HHS's entry says the protected health information included names, Social Security numbers, addresses, diagnoses and conditions, lab results, medications and other treatment information. Press coverage of the notice also lists dates of birth, medical record numbers and health insurance information, and says some people's email usernames and passwords were involved. What you got depends on your record.
Social Security numbers and dates of birth are what criminals use for identity theft. Treatment details are sensitive in themselves and let scammers write convincing messages posing as a clinic or insurer. Because the database was open to anyone, the company says it couldn't rule out that data was copied.
The company's response
Serviceaide offered complimentary credit monitoring, added security safeguards and retrained staff. If your email and password were in the exposed records, change that password wherever you reuse it.
