AI-powered hacking tools enabled a likely single attacker to breach multiple South Korean banks

A single suspected attacker breached several South Korean banks between late September and early October, and CrowdStrike says AI tooling made that scale possible. The attacker used ARTEX, an open-source Chinese penetration testing tool in which language models find security flaws automatically, along with Claude Code. More than 25,000 customer records were taken from Shinhan Bank alone.
