Advocate Aurora Health, a 26-hospital healthcare system in Wisconsin and Illinois, is notifying its patients of a data breach that exposed the personal data of 3,000,000 patients.
The incident was caused by the improper use of Meta Pixel on AAH's websites, where patients log in and enter sensitive personal and medical information.
The tracker also sends sensitive data to Meta and is then shared with a massive network of marketers who target patients with advertisements that match their conditions.
In August 2022, U.S. healthcare provider Novant Health disclosed its improper use of Meta Pixel in its implementation of the 'MyChart' portal, exposing 1.3 million patients.
The 'MyChart' patient portal is also used by AAH, along with another platform named 'LiveWell,' both of which had active Meta Pixel trackers.
AAH has also compiled a FAQ page to help patients find answers to common questions about the data breach.
