KB Kookmin Bank Launches AI-Based Next-Generation Voice Phishing Monitoring System

[Asia Economy Reporter Kim Hyo-jin] KB Kookmin Bank announced on the 11th that it has established and implemented an 'AI-based Next-Generation Voice Phishing Monitoring System' to protect financial consumers.

This system was developed to respond to increasingly sophisticated voice phishing scam techniques. To this end, AI and big data were integrated into the existing system over approximately eight months starting last year to complete it.

KB Kookmin Bank stated that the number of cases involving fraudulent accounts decreased by about 42% from May to July during the pilot operation of the AI-based next-generation voice phishing monitoring system, compared to the period when the existing system was in operation. Through this, KB Kookmin Bank explained that it has prevented a total of about 1,450 cases and financial fraud damages amounting to approximately 15 billion KRW, including the pilot operation period this year.

KB Kookmin Bank said, “We will do our best to proactively protect customers from voice phishing damage by stabilizing and advancing the next-generation monitoring system through continuous AI learning in the future.”

To prevent voice phishing scam damage, KB Kookmin Bank introduced the RCS (Rich Communication Service)-based messaging service in June, the first in the banking sector, which allows customers to verify bank logo information in text messages. The RCS-based messaging service is effective in preventing customer fraud damage caused by phishing messages because the company logo and name are displayed in the sender information even if the customer has not saved the phone number.

The voice phishing malicious app blocking service, which has been in operation since April, has blocked about 20,400 malicious apps to date. This service guides customers using the KB Star Banking, Liiv, and Liiv Talk Talk apps to delete the app from their smartphones if a 'malicious app of unknown origin' is detected when running the app.

A KB Kookmin Bank official said, “About 20% of customers do not delete the malicious apps even after receiving deletion guidance,” and urged, “If you use financial services without deleting malicious apps, you may continuously be exposed to voice phishing risks, so you should delete malicious apps immediately upon receiving guidance to prevent damage in advance.”
