• •LG Uplus implements a 24/7 AI monitoring system to combat holiday phishing threats.

On September 13, 2026, LG Uplus announced a 24-hour special response system utilizing its AI-based Secure.AI+ to combat a surge in voice phishing and smishing attacks during the Chuseok holiday. The telecom carrier aims to protect customers from malicious texts impersonating delivery services and fraudulent investment apps. These attacks can lead to the installation of malware that turns smartphones into 'zombie phones,' allowing criminals to manipulate calls and intercept communications. LG Uplus will operate a dedicated monitoring team in Seoul, enhancing tracking and blocking of malicious app control servers. The company has established a hotline with police for rapid response to confirmed infections and alerts customers via KakaoTalk if their devices are compromised. Continuous training of the AI system on spam patterns is also part of the strategy. Precautionary measures have been advised for customers, including avoiding links from unknown sources.
