St. Luke’s is a Milwaukee-based hospital subsidiary of Advocate Aurora Health. It was renamed– for the third time– in 1940 to St. Luke’s when the Lutheran Church took it under its wing. St. Luke’s was home to the first open-heart surgery in Wisconsin.

The breach resulted from a lack of security measures on a third party’s side. This third party, called Adelanto Healthcare Ventures (AHCV), alerted St. Luke’s to the breach on the day of its occurrence.
