GMOペイメントゲートウェイ announced that activity by an unauthorized user occurred on 30 October in its issuing support service provided to credit card companies and other clients. The incident involved the leakage of 69 records of user information relating to Life Card's Visa prepaid card, V Preca.
The leaked information comprised 63 sets of names, email addresses, telephone numbers and partial addresses; 3 sets of V Preca numbers, V Preca-specific security codes, expiry dates and names; and 3 partial V Preca numbers. Life Card processed account closures for the 3 records and said that no unauthorized use had been confirmed.
Life Card's V Preca is a reloadable Visa prepaid card that can be used for online payments and other transactions. GMOペイメントゲートウェイ's issuing support service provides via API the functions required for card issuance and transaction processing. The incident occurred within the scope of a specific function provided for V Preca and reportedly did not affect services for other customers.
The two companies will contact affected individuals individually, suspend part of the affected service, and proceed with countermeasures and security checks. They plan to announce the service resumption once security has been confirmed.
