Aurora Medical Center-Bay Area in Marinette, WI is notifying 27,137 patients that some of their protected health information has been exposed as a result of a January 1, 2020 phishing attack.
Several employees responded to the messages and disclosed their email account credentials, which gave the attackers access to their email accounts. The breach was discovered by the medical center on January 9, 2020. A password reset was immediately performed to prevent any further account access and the security breach was reported to law enforcement.
An internal investigation was launched to determine what information was accessed by the attackers, which revealed emails and attachments in the accounts contained the protected health information of patients. Aurora Medical Center has not received any reports indicating there has been any misuse of patient information, but it was not possible to rule out data theft.
A review of the emails in the accounts revealed they contained a range of PHI. The information varied from patient to patient and may have included names, first and last names, maiden name, marital status, date of birth, address, email address, telephone number, Social Security number, Medical record number, driver’s license number, medical device number, passport number, bank account number, health insurance account number, full face photograph, admission date, discharge date, and treatment date.
Steps have been taken to improve email security and employees have been provided with further security awareness training to help them identify phishing emails.
