GMO Internet Group confirmed the use of 'Artex' AI in attacks that were 'almost exclusively targeting Japan,' indicating a state-linked or state-sponsored campaign. The scale and AI-driven nature mark a notable escalation in cyber operations against Japan, though attribution remains partially inferred.
