Overview

• A report KT submitted to Rep. Hwang Jung-a shows the fraud spread beyond initial zones to southern Seoul and Goyang.
• KT revised its tally to 362 victims across 764 transactions and says abnormal attempts were blocked in the early hours of Sept. 5.
• The company is tracking cases tied to intercepted ARS authorization calls, while some victims report unauthorized PASS verifications and app logins.
• Lawmakers fault KT for piecemeal disclosures and a narrowly scoped probe, urging a full investigation and direct notifications to affected users.
• The government says it will toughen penalties for delayed breach reporting and allow probes without company disclosure, as a separate Lotte Card leak hit about 2.97 million customers.
