A data breach at hospital system giant Advocate Aurora Health may have exposed the information of as many as 3 million patients who use its online patient portals and other tools, the system said.
Advocate Aurora, which has 27 hospitals in Illinois and Wisconsin, said exposed patient data may include IP addresses; dates, times, and/or locations of scheduled appointments; a patient’s proximity to an Advocate Aurora Health location; information about patients’ provider; types of appointment or procedures; and communications between patients and others on MyChart.
Advocate Aurora said in a statement on its website that it has launched an internal investigation, and does not believe Social Security numbers, financial accounts, credit card or debit card information were leaked.
