Boannews reports that Korean builder GS E&C confirmed unauthorized external access around 22:15 on October 28, 2026 to the community facility reservation system (formerly FMCS) of its Xi apartments, leaking resident data, and reported it to KISA and the Personal Information Protection Commission ^[2]. Possibly leaked items include name, nickname, birth date, phone, gender, email, address, member number, residence type, one-way encrypted password and RF card number, varying by resident; GS E&C had declined a government probe, but the science ministry ordered an ex officio investigation on November 11 after a review committee deliberation ^[2][1]. GS E&C advises residents to watch for smishing, voice phishing and requests for personal data and to change their passwords, including the same password reused on other sites ^[2].
