PHOENIX — The information of millions of people has been compromised by hacks of Arizona’s largest health care system, it was announced Wednesday.
Banner Health said it was mailing letters to 3.7 million people — including patients, health plan members, beneficiaries, food and beverage customers, physicians and health care providers — who may have been affected by the hacks.
The agency said it discovered one hack in early July that targeted credit card data as it passed through payment processing systems. That cyber attack affects those who bought items from specific food and beverage locations between June 23 and July 7.
In another cyber attack, hackers may have gained access to patient information, including names, birthdates, addresses and possibly health insurance or Social Security information. The second hack was detected on July 13, but could have began as early as June 17.
Banner Health said the hacks did not affect all patients or health plan members.
The health care provider said it is working to both step up security measures and alert banks so affected cards can be monitored.
Those who may be affected by the cyber attacks are urged to keep an eye out for fraudulent charges on their account. Banner is offering a free one-year membership to a monitoring service for those whose information may have been compromised.
Customers with questions can call 855-223-4412 between 7 a.m. and 7 p.m. Pacific time, seven days a week.
