SK Telecom announced on January 13, 2026, that it blocked approximately 1.1 billion telecom fraud attempts in 2025, marking a 35% increase from the previous year. This surge in blocked attempts is attributed to the extensive deployment of artificial intelligence in their spam and phishing prevention systems. Despite the increase in prevention efforts, voice phishing losses in Korea continued to rise as scammers adapted their tactics.
