Banner Health said payment card, patient information and other data could have been pilfered
Banner Health, a provider of hospital services, has notified by mail 3.7 million people -- including patients, health plan members, healthcare providers and customers at its food and beverage outlets -- that their payment card and health plan data, among other information, may have been compromised.
The provider said Wednesday that it discovered on July 7 that cyberattackers may have gained access to computers that process payment card data at the 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 have been affected, the provider said.
Card payments for medical services were not affected, according to the investigation.
By July 13, Banner Health figured out that the attackers may have also got access to patient information, health plan member and beneficiary information, and information about physicians and healthcare providers.
