ARTEX AI agent goes closed-source after being linked to South Korean bank cyberattacks

The Straits Times, carrying Reuters reporting, says ARTEX’s developer announced on October 8 that the AI agent had been made closed-source, with no further public releases or maintenance support. The developer said ARTEX was intended for security testing and opposed illegal use. CrowdStrike said the likely suspect behind cyberattacks at South Korean banks used ARTEX and Claude Code. At least nine banks had disclosed attacks or been reported as targets since late September.
