70,000 Adventist Health Tulare Patients Impacted by Third-Party Breach

The incident happened to a third-party agency named Signature Performance.

By HFT Staff


A data security incident was recently discovered by Signature Performance, an agency working on behalf of Adventist Health Tulare to collect payment for services. We have no reason to believe information has been misused due to this incident. Signature Performance is informing all patients who might have been affected. 

Signature Performance detected suspicious activity on its network and immediately began investigating. The investigation included the assistance of third-party specialists and determined that an unknown party accessed certain files on Signature Performance’s network. Signature Performance discovered that more than 70,000 patients were affected by this breach. Every case is different for each patient, and each patient will receive a letter from Signature Performance regarding what information is impacted. 

In response to this incident, Signature Performance implemented an array of additional security measures to further minimize the risk of a similar incident occurring in the future. In an abundance of caution, Signature Performance is providing individuals access to single bureau credit monitoring, credit report and credit score services at no charge.
