Banner Health encounters data breach!

A massive cyberattack at Banner Health that began June 17 compromised the records of up to 3.7 million patients, health insurance plan members, food and drink customers, doctors and others at Arizona’s largest health-care provider’s locations.

Banner Health last month discovered unusual activity on its computer servers and uncovered evidence of two attacks with hackers accessing both payment-card records of food and beverage customers and patient records.

The Phoenix-based health system said on July 7 it discovered that cyberattackers may have accessed computer systems that process payment-card data at food and beverage outlets at some Banner Health locations.

Banner Health officials said the attackers sought payment-card data, including cardholder name, card number, expiration date and internal verification code of cards that were used at some Banner Health locations from June 23 through July 7. Customers can view a list of affected locations in Arizona, Alaska, Colorado and Wyoming here.

On July 13, Banner Health discovered that hackers also may have accessed patient and health insurance records. Those records may have included names, birth dates, addresses, doctors’ names, dates of service, claims information, health insurance information and Social Security numbers.
