Seoul:South Korea's state-run Financial Security Institute (FSI) has announced a data leak following a hacking attack that targeted its security assessment system, officials revealed on Tuesday.
According to Yonhap News Agency, the FSI, which is responsible for overseeing financial information from banks and insurers, detected the breach the previous day. Financial authorities have confirmed that unauthorized external access led to the data leak at 3 p.m. on Monday, prompting the institute to immediately block the affected system.
The FSI has since reported the incident to the Financial Services Commission and the Korea Internet & Security Agency (KISA). The leaked information was reportedly extracted from the FSI's website used for conducting security assessments of financial institutions. It included approximately 200 administration forms, around 300 pieces of personal data such as names and birthdates, and about 350 pieces of information linked to users of the system.
Officials have indicated that the attack involved a sophisticated cyber technique, where the hacker frequently altered internet protocol addresses to mimic legitimate access.
