South Korea's PIPC fined KT Corporation KRW 53.979 billion ($39 million) for data protection violations, escalating enforcement over a breach that exposed subscriber data and enabled fraudulent mobile payments. Investigators said the compromise affected 16,647 KT subscribers and led to losses of KRW 240 million ($167,400) for at least 368 customers. The regulator also said KT's controls were inadequate and that the company deleted logs from compromised servers during the investigation. The order requires KT to strengthen femtocell security, improve privacy governance, and expand ISMS-P coverage to its mobile network systems.
