ShinyHunters Leaks 45GB of Stolen Madison Square Garden Data, Including Personal Information of Celebrities and Executives Hackers from the ShinyHunters group have published nearly 45GB of stolen data from Madison Square Garden (MSG) online, exposing personal information of customers, high-profile sports figures, and celebrities. The leaked files include details such as addresses, contact information, and internal MSG communications, with some entries labeled under categories like "claim to fame" and "cost of talent." A sample reviewed by 404 Media revealed sensitive data tied to New York Knicks personalities, MSG executives, and their families. Among those listed were actor Ben Stiller marked as "Low Risk" and rapper A Boogie wit da Hoodie, the only individual labeled "High Risk." The leak also contained customer emails, including one complaining about MSG’s facial recognition systems, which have previously drawn scrutiny for invasive surveillance practices. ShinyHunters, known for past data breaches, posted the files on June 11, just days after the Knicks’ NBA Finals victory a timing that amplified attention on the breach. The group’s website included a ransom demand, stating that non-payment would result in public exposure of the data. MSG has not responded to requests for comment, and the group’s site indicates no ransom was paid. This incident follows a separate breach in March, when MSG confirmed a cyberattack targeting Oracle’s E-Business Suite, attributed to the Cl0p ransomware group. Cl0p had listed MSG as a victim in November 2025. The latest leak underscores ongoing cybersecurity risks for major entertainment and sports organizations.

Madison Square Garden Sports Faces Data Breach Amid Franchise Spin-Off Discussions Madison Square Garden Sports (MSGS), owner of the New York Knicks and Rangers, is navigating a dual challenge: a significant data breach and renewed investor scrutiny over a potential franchise spin-off. The company reportedly suffered a breach exposing over 26 million corporate and customer records linked to the Knicks, raising concerns about operational and reputational risks. The incident coincides with heightened attention on MSGS’s corporate structure, particularly a February 2026 board decision to explore separating the Knicks and Rangers into standalone public companies. Analysts and commentators, including Jim Cramer, have highlighted a "sum-of-the-parts" valuation argument, suggesting the franchises may be worth more individually than under the current structure. However, the breach adds pressure to MSGS’s near-term resilience, complicating investor confidence. Financially, MSGS projects $1.1 billion in revenue and $107 million in earnings by 2029, though some analysts remain bearish, citing flat revenue growth, media rights uncertainty, and reliance on just two teams. The breach and spin-off debate could further weigh on valuations, with some estimates suggesting the stock may be overvalued by as much as 50%. The situation underscores the balancing act for MSGS: managing long-term franchise value against immediate operational and cybersecurity risks. The outcome of the spin-off exploration and the fallout from the breach will likely shape the company’s investment narrative in the coming months.

Madison Square Garden Faces Lawsuit After ShinyHunters Data Breach Exposes Sensitive Visitor Data A New York resident has filed a negligence lawsuit against Madison Square Garden (MSG) following a data breach linked to the hacking group ShinyHunters, which exposed sensitive visitor information. The breach, disclosed in a complaint filed Tuesday in the U.S. District Court for the Southern District of New York, involved threat assessment reports, biometric data, and internal correspondence related to MSG’s facial recognition surveillance system. MSG, home to the 2026 NBA champion New York Knicks, collects facial recognition data on visitors as part of its security measures. The leaked information reportedly includes personal and biometric details, raising concerns over privacy and security practices. The lawsuit alleges that MSG failed to adequately protect the data, leading to its exposure. The breach highlights growing risks associated with biometric surveillance and the potential legal consequences for organizations handling sensitive data. No further details on the scale of the leak or affected individuals have been confirmed. The case is pending in federal court.
