Warner Norcross & Judd LLP is a law firm headquartered in Michigan, United States of America, that provides legal services to a range of clients. The firm’s work includes representing health plan organizations, as evidenced by the protected health information it maintained for those clients. Its practice areas involve advising on regulatory compliance, litigation, and transactional matters relevant to the sectors it serves. The firm operates from its Michigan headquarters and serves clients nationwide through its legal counsel. It maintains professional staff tasked with handling confidential client information as part of its service delivery. The firm’s role as a legal advisor places it in a position of trust regarding sensitive personal and health data.

In October 2021, the firm experienced a cyberattack that compromised the protected health information and sensitive personal data of over 255,000 individuals, including Social Security numbers, financial account details, prescription records, and decade‑old pharmacy claims. The breach was discovered nearly a year before public disclosure, drawing criticism for delayed notification and data retention practices. A forensic investigation found no evidence that the exposed data had been misused, though the volume of health information raised concerns about long‑term storage necessity. One health plan client confirmed that 120,000 of its members were affected by the incident. The event highlighted the firm’s responsibility for safeguarding extensive datasets entrusted by its clients. These facts constitute the confirmed profile of Warner Norcross & Judd LLP based on the available information.
