The maker of the agent used on Korean banks deleted its code.
CrowdStrike said on Wednesday that one attacker ran the open penetration-testing tool ARTEX against five South Korean lenders. Investigators read the attacker's own Claude Code logs, which held a résumé CrowdStrike thinks is his. ARTEX's author then removed the GitHub page, and the project is now closed to the public.
Why it mattersOpen security tools let small teams test their own systems, and let one person attack five banks. The author's own answer to that was to take the tool away from everyone.
