Hana Bank and KISA Establish Joint Defense Against Financial Fraud with Real-Time Verification Service

As financial fraud exploiting artificial intelligence (AI) and digital technology continues to rise, Hana Bank is implementing a system to proactively block these threats.

On June 26, Hana Bank announced that it has signed a memorandum of understanding (MOU) with the Korea Internet & Security Agency (KISA) to prevent and jointly respond to telecommunications financial fraud, including smishing.

This agreement aims to protect financial consumers from the increasing number of text message-based malware scams (smishing). According to KISA, the number of detected smishing messages surged from approximately 500,000 in 2023 to about 44.81 million in 2025, an increase of nearly 80 times in just two years.

In response, Hana Bank has developed a 'real-time smishing verification service' that integrates KISA data within its mobile banking app, Hana 1Q. When users receive a suspicious message, they can activate the service by clicking on the 'share message' feature within the app.

Alongside the service launch, Hana Bank plans to establish a dedicated monitoring team for its Financial Transaction Monitoring System (FDS) and hire additional staff for its help desk this year. The bank reported preventing voice phishing losses of 281.8 billion won in 2024 and 218.5 billion won in 2025.

Lee Ho-seong, President of Hana Bank, stated, "To combat increasingly sophisticated smishing crimes, proactive and technical joint responses are essential. We will make every effort to prevent financial crimes affecting the public through substantial and active consumer protection initiatives."
