AI Cyberattacks Target Major South Korean Banks, Prompting Security Alert

· Reviewed by the editor

South Korean financial authorities convened emergency meetings over the weekend after automated cyberattacks using AI agents targeted at least seven financial firms, including commercial giants Shinhan, KB Kookmin, and Hana Bank. Attackers utilized automated credential stuffing on external employee and partner portals to harvest customer identification records, with Welcome Savings Bank confirming leaks of up to 2,200 corporate records. While core financial ledgers and sensitive banking transaction passwords remain secure, authorities detected probing patterns across multiple servers. Regulators have instructed domestic lenders to overhaul credential safeguards and urged users to avoid reusing passwords.

So what

Change passwords immediately on any South Korean banking or financial apps you use, especially if you share the same password across multiple websites.
