Wolf Haldenstein Adler Freeman & Herz LLP, a New York-based law firm, experienced a cybersecurity incident in late 2023. This incident involved unauthorized access to the firm's network. The breach date is listed as December 13, 2023, and the company reportedly filed with state attorneys general in January 2025.
Reports indicate that the incident exposed personal information for approximately 3.4 to 3.5 million individuals. The data types involved include names, Social Security numbers, and protected health information (PHI). It remains unconfirmed if every affected person had all these data elements exposed, and a complete list of affected states has not been publicly identified.
While the firm itself issues breach alerts for other organizations, no official statement from Wolf Haldenstein regarding this specific incident was located. No class action lawsuit directly related to this breach has been identified, and there is no indication that this was a vendor or third-party breach affecting downstream customers; the incident is described as affecting the firm's own network.
