South Korea Warns AI-Linked Bank Hacks Exposed Data at 7 Financial Firms

3 articles · Updated · Financial Times · Oct 6

Summary

  • Seven South Korean financial firms suffered data leaks in a week of suspected AI-assisted cyber attacks, prompting President Lee Jae Myung to warn of a new threat and police to open a full investigation.
  • About 25,000 Shinhan Bank customers were exposed after an attacker bypassed identity checks on a loan-broker portal, while Yegaram Savings Bank lost data on roughly 40,000 customers and Welcome Savings Bank on 2,200 corporate clients.
  • The attacks appear to have hit weaker third-party systems rather than core payment networks, and identical or similar IP addresses suggest at least some breaches may have come from a single attacker.
  • Officials and researchers said evidence pointed to Artex, a Chinese-language open-source AI tool for finding and testing vulnerabilities, as regulators ordered 24-hour monitoring and asked cloud providers to block suspect overseas IPs.
  • The wave is likely to sharpen scrutiny of South Korean cyber security after earlier breaches at Coupang, TVing, LotteCard and KT, and amid wider global concern over AI-enabled hacking.
