In August 2023, **Hospital Sisters Health System (HSHS)**, a Midwest-based network of 13 Catholic hospitals, suffered a **targeted cyberattack** compromising the **personally identifiable information (PII) and protected health information (PHI) of 882,782 individuals**. The breach exposed data including **names, addresses, dates of birth, medical record numbers, treatment details, health insurance info, Social Security numbers, and driver’s license numbers** after threat actors gained unauthorized access to HSHS’s network between **August 16–27, 2023**. HSHS agreed to a **$7.6 million settlement**, offering affected individuals up to **$5,000 per valid claim** for out-of-pocket losses, alongside **24 months of free credit/identity monitoring**. The incident led to **class-action litigation** alleging negligence, breach of contract, and unjust enrichment, though HSHS denied liability. The breach underscored systemic vulnerabilities in healthcare cybersecurity, prompting HSHS to commit to **enhanced data security measures**, though specifics were undisclosed. The financial and reputational fallout, combined with regulatory scrutiny, highlights the severe consequences of healthcare data breaches.
