With identity verification and public MyData out of service due to the fire at the Daejeon National Information Resources Service (NIRS), banking operations are also being disrupted. Major financial holding companies launched emergency responses to prepare for contingencies that could occur after weekday opening.
As of the 28th, according to the financial sector, the bank services most affected include verification of resident registration cards, passports, and foreigner registration. If authenticity verification becomes impossible, accounts cannot be opened or extended remotely through banking applications (apps). However, authenticity verification is possible using mobile IDs issued before the outage or a physical driver's license.
With a failure also occurring in the government's My Public Data, some general unsecured bank loans that use it are not operating. Another financial company also notified that the service to change the usage region of the people's livelihood recovery consumption coupons may not function smoothly. In addition, services such as Kookmin Secretary and the Digital Open Service are also down.
Major financial holding companies have activated emergency response systems. Shinhan Financial prepared to separate and switch systems immediately if an IT failure occurs to prevent a situation where all operations stop. KB Financial is operating a non-face-to-face emergency response council that includes Chair Yang Jong-hee and is conducting on-site checks of the response. Woori Financial also activated a crisis response council on the 26th to assess system impact and prepare alternative measures in case of problems.
In particular, for Korea Post's financial services, all services—deposits and withdrawals, transfers, use of automated teller machines (ATMs), and premium payments and payouts—are suspended. Government agency websites in the financial sector, including the Financial Services Commission, also remain inaccessible. The government plans to prioritize restoring Korea Post's financial services, as they are directly tied to the economic activities of low-income residents.
Government agency websites in the financial sector, including the Financial Services Commission, also remain inaccessible. Financial authorities held an emergency response meeting the previous day and asked financial companies to "clearly specify the details of anticipated financial service disruptions and available alternative transaction methods so that the public does not feel inconvenienced, and to inform them in detail in a timely manner."
The Central Disaster and Safety Countermeasures Headquarters of the Ministry of the Interior and Safety said that as of 7 a.m. that day, more than 50% of network equipment had been activated and 763 out of 767 core security devices had been restarted. The government aims to sequentially restart 551 services during the day. However, it is expected to take time to restore the systems in the data center directly affected by the fire.
