SK Telecom faces fines of up to 30 million won and is mandated to implement security reforms following a data breach affecting 26.96 million users. The breach exposed sensitive USIM information due to poor management and unencrypted data. The government has ordered enhanced security measures, including improved password controls and direct reporting to the CEO by the chief security officer. In response, SK Telecom plans to invest 700 billion won in cybersecurity and has launched a 500 billion won customer relief program. The company also revised its 2025 sales forecast down to 170 trillion won, and its shares fell nearly 6%.
