FSI Confirms Data Leak After Hacking Attack
South Korea's state-run Financial Security Institute (FSI) reported a data leak following a hacking attack targeting its security assessment system, officials said Tuesday. The FSI, which oversees financial information protection, confirmed the leak on November 9 and notified authorities including the Financial Services Commission, according to Yonhap and the Korea Times. The attack is part of a broader wave of cyberattacks on the financial sector; earlier, Mirae Asset Securities confirmed a breach compromising the personal data of about 39,000 customers and employees, prompting an on-site inspection by the Financial Supervisory Service, and the regulator reported over 470,000 personal data records leaked from 37 financial firms over the past month with funds stolen estimated at 1 billion won ($745,000). Korean media and blogs are reacting with alarm, framing the FSI breach as a serious blow—one headline calls it "문지기도 뚫렸다" (even the gatekeeper was breached)—and urging stronger cybersecurity measures across the sector.
