South Korea’s LG Uplus will launch an AI-driven anti-phishing feature in its ixi-O AI agent starting June 30.

The tool detects AI-generated voices during phone calls to combat rising voice phishing and deepfake scams.

It can identify manipulated voices within five seconds and alerts users to potential fraud, such as impersonation or fake hostage situations.

The system was trained on 3,000 hours of call data, or about 2 million calls. It uses voice activity detection, speech-to-text, and anti-spoofing analysis.

The feature runs on-device without storing data externally, reducing privacy risks.

LG Uplus will also analyze calling patterns from flagged numbers and collaborate with the National Forensic Service to compare voices with a phishing criminal database.

🧠 Food for thought

1️⃣ Voice phishing attacks are rapidly evolving with AI, creating urgent market need

LG Uplus’s technology addresses a rapidly growing threat landscape where voice phishing attacks have increased significantly as AI improves voice cloning capabilities 1.

The timing is critical as AI-powered attacks are becoming more sophisticated and harder to detect, with 73% of enterprises experiencing AI-related security breaches in the past year at an average cost of $4.8 million per incident 1.

These AI-enhanced attacks are particularly challenging to combat because they take longer to identify and contain—averaging 290 days compared to 207 days for traditional breaches 2.

The company’s focus on detecting “abnormal high-frequency noise or unnatural variations in pronunciations” directly addresses the technical vulnerabilities in current deepfake voice technologies that organizations and individuals struggle to identify without assistance.

2️⃣ On-device AI represents a strategic shift in telecommunications security

LG Uplus’s approach of using on-device AI rather than server-based processing represents an important evolution in telecommunications security architecture.

By processing voice analysis locally on the device without storing user information on telecom servers, LG Uplus is addressing growing privacy concerns while still providing advanced protection—a balancing act that’s becoming increasingly important as the AI cybersecurity market is projected to grow from $24.82 billion in 2024 to $146.5 billion by 2034 1.
