The South Korean Ministry of the Interior and Safety reported that a fire broke out at the National Information Resource Management Institute on the evening of September 26, causing complete destruction of the government's core file storage system. Nearly seven years of work documents of approximately 750,000 civil servants since 2018 were entirely lost due to the lack of external backups. This incident has caused disruptions in the operations of multiple departments, becoming the most severe government data security incident in recent years.
