Unauthorized access occurred in part of the transaction system operated by GMOペイメントゲートウェイ, and information including prepaid card numbers may have leaked, including information processed by a specific function provided to Life Card. A total of 69 records are affected, and part of the service is currently suspended while countermeasures are implemented.
GMOペイメントゲートウェイ (GMO-PG) explained that the affected portion of the transaction system it disclosed as having been subject to unauthorized access was a specific function provided to Life Card. The information that may have leaked includes names, email addresses and telephone numbers, as well as numbers from V Preca, a prepaid card issued by Life Card.
A total of 69 records are reportedly affected. The company said that the same service provided to other companies and its payment processing services operate on separate platforms and are not currently affected. The incident occurred on 30 October. Part of the affected service is currently suspended while the cause is investigated and measures to prevent recurrence are implemented.
The incident is attributed to unauthorized activity in part of a payment system provided by a GMO subsidiary. GMO-PG is expected to disclose again whether there was an impact and the specific scope of any impact based on the results of its investigation.
The announcement is being compared with previous reports of unauthorized access incidents involving the GMO group, and increased system monitoring and stronger security measures are being sought to prevent similar incidents from recurring.
