Meta Pixel breach affects 3 million patients

A healthcare system in Wisconsin and Illinois has had to notify patients of a data breach that exposed millions of personal details. Advocate Aurora Health, which runs 26 hospitals, reported that improper use of a Meta Pixel caused the attack. This affected patients’ login areas, where they would enter personal medical information. The Meta Pixel JavaScript tracker is designed to study how users interact with the site, and then send this data to Facebook. Attacks of this type have happened before, including Novant Health in August 2022, which affected 1.3 million patients.
