Mirae Asset Life said it detected anomalies in some systems on October 25, 2026, recognised a cyber intrusion, and confirmed a personal data leak early on October 26 after analysis with an outside firm [1]. Leaked items vary by customer and include names, resident registration numbers, bank accounts and retirement pension data plus some employee data; according to Yonhap, the Financial Supervisory Service launched an urgent on-site inspection [1][2]. The company urges customers to beware of smishing and voice phishing impersonating it, not respond to or click links in messages of unclear origin, and not enter personal or financial details on request [1].
