Banner Health has notified by mail 3.7 million people that their payment card and health plan data may have been compromised. The provider said it discovered on July 7 that cyberattackers may have gained access to computers that process payment card data at food and beverage outlets at some of its locations. Payment cards that were used at these outlets at certain Banner Health locations from June 23 to July 7 this year may be affected. Card payments for medical services were not affected, according to the investigation, the provider said.”]
