South Korea’s science ministry classified incidents reported by Douzone as serious and formed a public-private investigation team on October 25. Abnormal access to the Smart A 10 development server and suspicious activity in the APO backup service are under examination, with possible exposure of some personal information disclosed. The affected population and scale remain unconfirmed, so the total number of service customers is not a breach-victim count. Customer companies should monitor official notices and individual notifications while checking relevant logs and potential impact.
