Cyberattack on major South Korean banks may have been carried out by one person using AI tools

An October 8 post citing a CrowdStrike report says a cyberattack on some of South Korea’s biggest banks the previous week may have been carried out by one person using ARTEX, DeepSeek v4.1-Flash, GLM-5.3, Grok 4.6 and Claude Code. Another post claims the suspected attacker left directory listing enabled on their server, and that researchers found files and reviewed Claude Code sessions.
