- GMO Internet Group's information security subsidiary discovered six attacking devices exclusively targeting Japanese firms and identified Artex as an autonomous AI agent employed in the cyberattacks.
- Artex is described as a China-linked AI penetration tool with high capability of diagnosing system vulnerabilities, deployed against companies in retail, logistics, and financial sectors.
- Eight Japanese companies disclosed in September and October that data had been leaked or possibly leaked following unauthorized access incidents.
- GMO announced the findings on October 19 via its blog, pinpointing Artex as the tool used in the attacks on Japanese entities.
- A separate investigation by another security firm linked Artex to a series of unauthorized accesses against South Korean financial institutions since late September.
- Cybersecurity minister Toshiharu Furukawa said at an October 20 press conference that the government is analyzing whether AI was used maliciously and vowed continued efforts to prevent cyberattacks.
Why it matters: Eight companies across three sectors confirmed data leaks in just two months, and the same China-linked AI tool hit South Korean financial institutions — pointing to a coordinated, cross-border AI-powered campaign targeting two US-aligned economies. Japan's cybersecurity minister publicly committing to a formal AI-malice probe marks a notable policy escalation against AI-driven intrusion tools.
