Bell Ambulance reported that a February 2025 network intrusion led to the compromise of protected health information for 237,830 individuals, after unauthorized activity was detected on Feb. 13, 2025. The organization said the exposed data can include names, dates of birth, Social Security numbers, driver’s license numbers, financial account information, medical information, and health insurance information; it offered 12–24 months of credit monitoring/identity protection and stated it was not aware of misuse at the time of notification.

Separately, Cornerstone Specialty Hospitals agreed to pay $2.35 million to settle a class action lawsuit tied to a data breach that reportedly affected nearly 500,000 individuals. The available reporting focuses on the settlement amount and impacted population size, indicating ongoing legal and financial consequences for large-scale healthcare data exposure even when technical details of the underlying intrusion are not publicly described in the same source.
