Advocate Aurora patient data breached

Advocate Aurora Health, the largest hospital system in Illinois and Wisconsin, said data for an unspecified number of its 3 million patients was breached.

In a statement, Advocate officials said they "are not aware of any misuse of information" from the recent incident.

In a statement on its website, the hospital system blamed the use of tracking technology from sources such as Facebook and Google that was intended to "evaluate information concerning the trends and preferences of its patients as they use our websites."
