A string of hacking incidents in South Korea’s financial sector has led to confirmed personal data leaks at savings banks and mutual finance groups, prompting authorities to step up inspections and security requirements. Banks are moving to raise cybersecurity spending and expand fraud prevention systems using AI. Market volatility and a steep stock selloff also drew a policy response. Political debate intensified over postponing digital asset taxation and regulating exchange shareholders.

South Korea\'s Personal Information Protection Commission on Monday issued preventive guidelines as hacking that exploits security vulnerabilities using AI increases and concerns grow over data leaks and secondary 피해. The commission advised individuals to withdraw from unused websites, use services to check identity verification history, and regularly confirm account leaks or identity theft through public services. It also provided contact points for reporting privacy violations and financial fraud and urged organisations to review systems, devices and APIs handling personal data.
