What happened
On June 8, 2026, internal security monitoring alerted SPay, Inc., which does business as Stack Sports, to suspicious activity affecting its Sports Affinity platform. A forensic investigation confirmed that an unauthorized actor had embedded malicious code in the platform's checkout flow, capturing payment details that customers entered during online transactions between May 8 and June 22, 2026. According to the company's notice filed with the California Attorney General, the company engaged incident-response and cybersecurity counsel to investigate the intrusion and assess the scope of transactions involved.
Stack Sports reports that it removed the unauthorized code by June 10, 2026 and forcibly cleared residual elements from customer browser caches by June 22, 2026. A transaction-by-transaction review completed on July 17, 2026 identified the affected individuals, and the company began mailing notification letters on July 27, 2026. The notice states that the information potentially captured includes cardholder name, payment-card number, expiration date, card security code (CVV), and, for customers who paid by ACH or eCheck, checking-account number. Stack Sports says no account credentials, Social Security numbers, or driver's-license numbers were involved. The company is offering 24 months of complimentary IDX credit monitoring and CyberScan internet monitoring, a $1 million identity-theft insurance policy, and fully managed recovery services, with enrollment required by October 27, 2026 using the code printed in each letter.
Because the incident involved live payment-card and bank-account data entered at checkout, affected customers may face a heightened risk of fraudulent charges and unauthorized account activity. Whether Stack Sports' pre-breach security practices for its Sports Affinity checkout pages met legal standards, the total number of individuals affected, and why the code remained active for roughly six weeks before it was detected are among the issues being evaluated.

Common questions
I received a data breach letter from Stack Sports. What should I do? +
Keep your notification letter, activate the free IDX credit and CyberScan monitoring using the enrollment code printed in your letter before the October 27, 2026 deadline, and closely monitor your payment-card and bank statements for unfamiliar activity. Because payment-card and checking-account data may have been captured, contact your card issuer or bank to report suspicious charges and request a replacement card or account number. You may also consider a credit freeze and can contact a data breach attorney for a free consultation. Accepting the free monitoring does not waive your right to sue.
Am I eligible to join a class action against Stack Sports? +
If you received a July 2026 breach notice from Stack Sports, or entered payment information on a Sports Affinity checkout page between May 8 and June 22, 2026, you are likely eligible for a free case evaluation.

What personal information was exposed in the breach? +
According to the company's public notice, the malicious code could have captured payment details typed into the Sports Affinity checkout pages during the breach window, including cardholder name, payment-card number, expiration date, card security code (CVV), and, for customers who paid by ACH or eCheck, checking-account number.
