Holland & Knight Listed by Leakeddata Ransomware Group

If you are a customer of Holland & Knight, here’s what is being claimed, and what it would mean for you.

Holland & Knight was listed on Leakeddata's leak site. Leakeddata claims to have stolen internal data. This is the group's claim, not a confirmed finding.

Holland & Knight Listed by Leakeddata Ransomware Group

Holland & Knight has been listed on the LeakedData ransomware extortion leak site. The group claims the law firm is part of their double-extortion campaign, but the company has not publicly confirmed any incident as of this writing.

You can’t unleak data. You can take away what it’s worth.
A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

This means the only information currently available comes from the attackers themselves. No independent party has verified that a breach took place, what records may have been involved, or whether any client data changed hands. The filing date is September 01, 2026. The record does not state how many people were affected, does not list any specific categories of information, and does not provide an incident date.

What a Leak-Site Listing Actually Establishes

Ransomware groups frequently publish the names of law firms on leak sites as leverage in extortion negotiations. These listings are marketing material produced by the attackers. They are sometimes genuine, sometimes exaggerated, sometimes recycled from older incidents, and occasionally fabricated to pressure the target into paying.

A listing alone does not constitute confirmation that any breach occurred or that any client files were taken. Real confirmation would require an admission by the company, a regulatory filing with specific details, or forensic evidence released by a trusted third party. Until one of those appears, the incident remains an unverified claim. This distinction is important because many law firms and their clients treat every leak-site posting as proven fact, even though history shows a meaningful percentage of such claims never receive independent corroboration.

The Pattern Law Firms Face Repeatedly

Ransomware operators have made law firms a consistent target class in double-extortion operations. The attackers know these organisations hold sensitive client records across litigation, mergers, intellectual property, and regulatory matters. A single successful intrusion can give them leverage over both the firm and its clients.

Because the record here provides no technical details, it is impossible to say how initial access was gained or whether preventive controls failed. What is known is that this class of claim continues regardless of the actual security practices at any single firm. The next listing will appear, and the same uncertainty will apply. Clients cannot eliminate the risk that their law firm appears on a leak site, but they can limit what a stolen credential would allow an attacker to do.

What Remains Permanent and What You Still Control

What you can still control is access to your Holland & Knight account and any linked services. A single reused password across multiple sites creates an identity chain that attackers exploit. By isolating the credential tied to this firm you reduce the blast radius of any potential compromise.

Concrete Actions That Address This Specific Claim

  • Enable multi-factor authentication on the Holland & Knight account if it is offered. A second factor blocks credential-stuffing even if the password has been obtained.
  • Review recent account activity and statements for any changes you did not authorize. Law-firm client portals sometimes contain billing records or case updates that could reveal broader activity.
  • Monitor for any direct notification from Holland & Knight. Because the record contains no incident date, a letter sent to your last known address is the only practical way to learn whether your specific records were included. If you have moved in recent years, contact the firm directly to confirm your current status.

Unverified claim — what this report is
This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.

Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source.
