Plaintiffs have filed two class action lawsuits against Greenberg Traurig in the Southern District of New York following the firm's disclosure of a data breach this month. The litigation centers on the exposure of sensitive personal information handled by the organization.
Why it matters
The filings follow a data security incident that compromised client information, highlighting the ongoing legal risks firms face when sensitive data is exposed. These lawsuits represent the immediate legal challenge the firm must now address regarding its handling of protected data.
Two 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 initiated in Manhattan. These filings serve as the formal mechanism for plaintiffs to seek damages following the disclosed data exposure.
The players
