A data breach at Cooper University Health Care exposed the personal and medical information of 57,412 individuals, including names, Social Security numbers, dates of birth, health insurance details, and other sensitive data. The unauthorized access occurred around May 14, 2024, but the breach was only confirmed after a lengthy investigation concluding on March 26, 2025. The compromised data may have been exfiltrated without permission, raising concerns over identity theft and fraud. In response, Cooper established a toll-free support line and offered free identity protection services to affected patients. The health system, which operates hospitals, urgent care centers, and outpatient facilities across New Jersey, emphasized its commitment to patient security and transparency, though the exact number of impacted New Jersey residents remains undisclosed. The breach poses significant risks, including potential financial fraud, medical identity theft, and long-term reputational damage to the institution.
