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.
