Shinhan Card said Wednesday that a financial regulator’s investigation found about 2,600 cases within a merchant data breach disclosed in December 2025 also involved leaked credit information.
In a notice posted on its website, the company said the findings relate to a personal data leak that occurred on Dec. 23, 2025, and that the regulator confirmed additional exposure of credit information.
Shinhan Card said it cannot individually notify 52 of the roughly 2,600 affected cases because the data subjects cannot be identified, and it is issuing the public notice for that reason.
The company said it took steps to block further leakage as soon as it became aware of the incident in December and completed a review of related internal processes. It emphasized that no separate leak has occurred since that time.
Shinhan Card previously reported that the December incident involved 192,088 leaked records tied to merchants. It said the latest review confirmed that about 2,600 of those cases qualify as leaks of personal credit information.
The company again apologized for the leak of personal credit information and said it will work to ensure customers can use Shinhan Card services with confidence.
