Greenberg Traurig Data Breach

Greenberg Traurig, LLP, an international law firm with roughly 2,750 attorneys across 49 offices, reported a security breach to the Vermont Attorney General on September 8, 2026. A ransomware group claims it’s behind the intrusion.

Greenberg Traurig, LLP filed a security-breach notice with the Vermont Attorney General on September 8, 2026, confirming an incident affecting 10 Vermont residents, with Social Security numbers identified as the exposed data category. Greenberg Traurig has no office in Vermont, which suggests the affected population reaches well beyond any single office and is likely national in scope. The firm has not disclosed a total number of affected individuals, and Vermont is currently the only jurisdiction with a public filing on record.

A Ransomware Group’s Claim

A ransomware and extortion group calling itself SilentRansomGroup listed Greenberg Traurig on its dark web leak site around September 2-3, 2026, roughly a week before the Vermont filing, and reportedly threatened to publish data if the firm doesn’t negotiate. Greenberg Traurig has not publicly confirmed this group’s identity or the scope of what it claims to hold. Emery | Reddy is presenting this as an unverified claim from a criminal group, not a fact confirmed by the firm — the only confirmed detail is the Vermont regulatory filing itself.

Why a Law Firm Breach Is Different

Greenberg Traurig isn’t a typical consumer-facing company — it’s a law firm, and the data a law firm holds includes confidential files belonging to its own clients, not just its own employees. When a law firm is breached, it’s often acting as a custodian of other people’s confidential information rather than the direct data subject, which can broaden who’s affected well beyond the firm’s own personnel and clients of record.

Part of a Larger Pattern

Greenberg Traurig is the fourth large law firm to confirm a data security incident on public regulatory record within about three weeks, following breaches previously confirmed at Troutman Pepper Locke, McDermott Will & Schulte, and Eckert Seamans Cherin & Mellott. A separate filing from Wilmer Cutler Pickering Hale and Dorr, reported to Delaware regulators on August 12, 2026, disclosed more than 911,000 affected individuals. Law firms that hold client-confidential files in volume appear to be an active target for these kinds of intrusions.
