Two class action lawsuits have been filed against the law firm Greenberg Traurig in the Southern District of New York. These legal actions follow the firm's recent disclosure of a data breach that exposed sensitive personal information.
Why it matters
The litigation highlights the growing legal risks organizations face when cybersecurity incidents compromise the private data of their clients or employees. Class action lawsuits serve as a mechanism for affected individuals to seek collective legal recourse following such exposures.
Two class action lawsuits, Addison et al v. Greenberg Traurig (No. 1:26-cv-07793-JAV) and Hancock v. Greenberg Traurig (No. 1:26-cv-08182), have been filed in the Southern District of New York. These filings follow a September data breach disclosure.
The players
Greenberg Traurig
Greenberg Traurig is a global law firm that provides legal services across a wide range of practice areas and industries.

Plaintiffs initiated these proceedings in Manhattan federal court after the firm confirmed a security incident involving unauthorized access to sensitive data. The lawsuits allege failures in protecting private information, moving through the legal system as distinct class action cases.
Timeline
September 2026: Greenberg Traurig disclosed the data breach.
The Big Picture
This litigation follows the established pattern of class action filings in federal court that often follow large-scale data breach disclosures, similar to the 2021 T-Mobile data breach class action settlement. Such cases are becoming a standard industry response to corporate security failures.
Residents and clients whose information may have been exposed should monitor their financial statements and credit reports for suspicious activity. The ongoing federal court proceedings may lead to court-mandated notifications or security improvements for those impacted by the breach.
The takeaway
Entities holding sensitive data are increasingly held accountable through collective legal action when security protocols fail. Individuals affected by such breaches should take immediate steps to secure their personal credentials and monitor for identity theft.
