high severity November 21, 2025 · 4 min read Unverified claim — what this is

MSG.COM Listed by clop Ransomware Group

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

MSG.com is a website owned by The Madison Square Garden Company, a sports and entertainment company based in the United States. The site features content pertaining to the company's various properties, including the New York Knicks, the New York Rangers, and Madison Square Gardens. It provides news, updates, event schedules, ticket purchasing options, and more.
— from Clop’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.

On November 21, 2025, the clop ransomware group added msg.com to its public leak site, claiming that internal files had been exfiltrated from the company behind the New York Knicks, New York Rangers, and Madison Square Garden.

Already exposed?

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 582 companies.

Reported Details from Reporting

Public reporting indicates the incident stems from a ransomware attack in which attackers gained access to MSG’s systems, copied internal documents, and later listed the victim on their dark-web leak page when negotiations apparently failed. The exact number of people whose information appears in the files remains unknown, but the data includes a range of sensitive internal records. Available reporting describes the exposed material as internal files rather than a structured database of customer records, though such documents frequently contain employee, vendor, partner, and customer details.

November 21, 2025 marks the date the listing appeared. The clop group’s leak site, accessible only via Tor, serves as both proof of compromise and a countdown for further data publication if demands are not met.

Why This Matters for You and Your Family

When a company like MSG suffers a breach, the information that leaks can reach far beyond employees. Tickets, season passes, hospitality packages, and fan-club sign-ups often tie personal details—names, addresses, email addresses, phone numbers, and payment records—to your household. If any of those records sit inside the stolen files, your family’s contact information may now be in the hands of criminals who openly sell or publish it.

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.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
