Full breach record for Madison Square Garden Entertainment Corp.5 incidents on file

The Madison Square Garden Company (MSG) notified customers of a payment card data breach affecting transactions at MSG venues in New York and Chicago between November 9, 2015, and October 24, 2016. External unauthorized access to MSG's payment processing system allowed the installation of a program that captured magnetic stripe data, including card numbers, names, expiration dates, and verification codes. MSG discovered the incident in late October 2016 after banks identified suspicious transaction patterns. The company engaged security firms, contained the breach, and implemented enhanced security measures. No specific count of affected individuals was disclosed.
