MADISON SQUARE GARDEN ENTERTAINMENT CORP. was the subject of a data breach notification filed with the IL Attorney General. The AG filing was recorded on December 16, 2025.
From the AG filing description
Madison Square Garden Entertainment Corp. operates at the intersection of live entertainment, hospitality, and digital ticketing, managing world-renowned venues, iconic productions, and extensive customer engagement platforms. Because of this dynamic business model, the company routinely collects and processes vast volumes of personal, financial, and behavioral data from millions of patrons, event attendees, employees, and corporate partners. This information is gathered through digital box offices, mobile applications, loyalty programs, merchandise purchases, and direct-to-consumer marketing initiatives. Consequently, Madison Square Garden Entertainment Corp. functions as a massive repository of sensitive consumer and employee details, creating a high-value target for cybercriminals seeking to exploit inadequately secured digital infrastructure. In 2025, Madison Square Garden Entertainment Corp. reported a significant data security incident to the Illinois Attorney General, alerting affected individuals that their private information may have been compromised. While the exact vector of the attack remains under investigation, breaches involving major entertainment and ticketing conglomerates typically involve sophisticated external intrusions, ransomware deployments, or third-party vendor vulnerabilities that bypass perimeter defenses. Modern cyber threats target the complex supply chains and interconnected databases that entertainment enterprises rely on to manage high-volume ticket sales and customer relations, often leaving network perimeters exposed to unauthorized third-party extraction over extended periods before detection. The exposure resulting from this incident potentially compromises a wide array of sensitive information, including full names, mailing addresses, email addresses, phone numbers, payment card details, and account credentials. When consumer and employee data of this nature falls into unauthorized hands, victims face severe, multi-faceted risks. Cybercriminals can exploit financial account details to execute unauthorized fraudulent transactions or initiate account takeovers across other platforms using recycled credentials. Furthermore, personally identifiable information can be leveraged for sophisticated phishing schemes, targeted identity theft, and synthetic fraud, leaving affected individuals vulnerable to long-term financial distress and the exhausting burden of monitoring their credit profiles. As a commercial entity handling sensitive consumer and employee data, Madison Square Garden Entertainment Corp. had a strict legal and regulatory obligation to implement robust cybersecurity measures. Under state consumer protection statutes, such as the Illinois Consumer Fraud and Deceptive Business Practices Act, along with established common-law negligence principles, companies are required to maintain reasonable security procedures appropriate to the sensitivity of the data they store. Failing to encrypt payment data, leaving databases unprotected against known vulnerabilities, or neglecting to properly vet third-party vendors constitutes a clear breach of these legal duties. This incident suggests a potential failure in the company's duty of care, leaving its patrons and workforce exposed to preventable harm. Receiving an official data breach notification letter from Madison Square Garden Entertainment Corp. serves as formal legal acknowledgment that your personal information was compromised due to inadequate corporate security practices. Under modern jurisprudence, this notification establishes the legal standing necessary to participate in a class action lawsuit aimed at holding the company accountable for failing to safeguard your data. Crucially, you do not need to prove that you have already suffered actual financial loss or identity theft to join a class action; the increased risk of future harm and the loss of privacy are legally cognizable injuries. Our firm handles these complex data privacy cases on a strict contingency fee basis, meaning you pay nothing out of pocket, and we only recover fees if we successfully secure a recovery on your behalf.

Common categories of compensation in data breach class actions
Courts recognize that the time spent monitoring accounts, placing credit freezes, and dealing with the aftermath of a breach has real economic value. This category of damages is recoverable even without direct financial loss.
When login credentials are exposed, the costs of downstream account compromises — password managers, security audits, and recovery costs for hijacked downstream accounts — can be recovered. Courts in recent class actions have awarded damages for credential exposure even without proven misuse.
Several state data breach laws provide for statutory minimum damages — fixed amounts recoverable per affected individual regardless of actual loss. These provisions exist specifically to make legal action viable for victims who have not yet experienced direct harm.
Note: an attorney general breach filing does not by itself establish a settlement fund, a payment amount, or a claim deadline. If an official settlement notice is later issued, rely on that notice for payment details and deadlines.
Applicable State Law
This breach was reported under the Illinois Personal Information Protection Act (PIPA), which mandates notification and establishes your right to seek damages.
No. Under Illinois Personal Information Protection Act (PIPA) and federal law, the unauthorized exposure of your personal data — regardless of whether it has been actively misused — can be sufficient grounds for a claim. The breach itself is the injury.
Nothing. The Law Office of David S. Harris handles data breach cases on contingency — you pay zero upfront and owe nothing unless compensation is recovered.
Statutes of limitations for data breach claims vary by state but typically run 2–4 years. Depending on when you learned of the breach, you may still have time. Contact our office for a free eligibility review — there is no cost to find out.

Not necessarily. Many data breach victims are never notified directly. If your personal information was held by MADISON SQUARE GARDEN ENTERTAINMENT CORP. during the relevant period, you may still qualify even without receiving a letter. A free eligibility review can confirm your status.
