Patients of Trinity Health may have had some of their personal information compromised in a data breach in January.
The health network, which includes Trinity Health of New England, said it was notified by Accellion, a third-party vendor, on January 29 that there was a security issue with its system used for sending secure email.
Certain files on the server were downloaded by an unknown user on January 20, according to Trinity Health. The unauthorized user was able to take advantage of an unknown security flaw in the Accellion appliance, the company said.
The files that were downloaded contained information including patient names, addresses, emails, birth dates, healthcare provider, medical records numbers, lab results, medications, payment, payer names, and claims information.
