Suwon: The recent service disruption in Samsung Pay, a mobile payment system operated by Samsung Electronics Co., was caused by a firewall error at a data center in Suwon, just south of Seoul, government officials said. On June 2, Samsung Pay experienced service errors lasting over three hours beginning at around 7 a.m., affecting card payments and new card registration.
According to Yonhap News Agency, Samsung Electronics restored the service by switching operations from its main data center operated by Samsung SDS Co. in Suwon to a backup center run by KT Corp. in Seoul. The company initially said the failure appeared to stem from network line issues with card companies.
In interim findings submitted to Rep. Kim Jang-kyom of the main opposition People Power Party, the Ministry of Science and ICT identified the internal firewall on the dedicated network connecting to card companies at the Suwon data center as the point of failure. The ministry noted that a further investigation is needed to pinpoint the detailed cause, including potential issues in the network equipment.
It added that there was no evidence of a cyberattack, citing the results of regular and follow-up security inspections conducted by Samsung SDS.
