Signs of hacking targeting the financial sector have spread beyond banks and secondary financial firms to internet banks and the insurance and securities industries. South Korea\'s Financial Supervisory Service identified 33 IP addresses linked to hacking attempts, or 28 excluding duplicates, and asked financial firms to block them and conduct self-checks. Police formed a dedicated team and opened a formal investigation. The government called for swift clarification of the circumstances and measures to minimise damage.

South Korea\'s telecommunications industry has pushed back against discussions on extending no-fault compensation for voice phishing losses to telecom carriers. The Korea Telecommunications Operators Association said carriers do not manage financial transactions and are restricted from arbitrarily listening to or checking call and text content. It said telecom networks are a channel for information, while transfers and withdrawals occur within the financial system. It cited overseas examples and said carriers will keep strengthening prevention efforts with the government and finance sector.
