SK Telecom’s AI-Driven Anti-Fraud Efforts Boost Stock Amid Rising Phishing Losses

SK Telecom's stock (SKT) edged higher after the South Korean telecom giant revealed it blocked 1.1 billion spam calls and phishing attempts in 2025 using advanced AI filters. The 35% year-over-year increase in prevented fraud attempts demonstrates the efficacy of its machine learning systems, which analyze call patterns to flag suspicious activity—even from unreported numbers.

While the volume of voice phishing cases declined, financial losses per incident nearly doubled, exceeding 1 trillion won ($718 million) in the first 10 months of 2025. The paradox highlights evolving scam tactics—fraudsters now target fewer victims with higher-value attacks. SK Telecom's dual-layer AI now intercepts 250 million robocalls and 850 million malicious texts monthly.

Industry analysts suggest RCS verification could further reduce false positives. 'When telecoms weaponize AI against fraud, they don't just protect customers—they protect their own valuation,' noted a Seoul-based fintech strategist. The stock's uptick reflects market confidence in proactive cybersecurity investments.
