AI Case Study

SK Telecom to prevent voice phishing cyber attacks using AI

SK Telecom in collaboration with South Korea's finance watch dog, the Financial Supervisory Service (FSS), plan to combat voice phishing attacks with the use of AI. Based on the watchdog's provision of financial fraud data, the company is building an AI system aimed at alerting callers if a voice phishing call is being suspected. The difference with older practices to identify such cases is that the system will base its predictions on the context of the calls rather than preset keywords. The company has stated that the system is expected to launch in the first half of 2019.

Project Overview

"South Korea's finance watch dog, the Financial Supervisory Service (FSS), together with SK Telecom, will develop AI to prevent voice phishing attacks.

The FSS will provide its data on financial fraud while the telecommunications carrier will build an AI system that alerts callers when it is suspected that they have received a voice phishing call.

Existing filtering methods detect phishing attacks based on the use of certain keywords. The new AI system will detect phishing attacks based on context, the FSS said.

The service is expected to roll out sometime in the first half of next year.

"Phishing, whether through voice or email, has risen globally as a serious threat. Cybersecurity company FireEye, which examined over half-a-billion emails sent between January and June 2018, found that one in 101 emails were classified as being malicious.

The FSS said damages caused by voice phishing in the first half of this year amounted to 180.2 billion won ($159 million), an increase of a staggering 73.7 percent from a year ago."
