Overnight warnings about two critical flaws in programming language PHP, used by 70% of websites, turned into preventive shutdowns across Japan. Banks including MUFG and Mizuho, JR operators, retailers such as Sukiya, the Japan Meteorological Agency, municipalities and ministries suspended services to patch, with Prime Minister Takaichi's own site taken offline and an unusual call for updates.
By afternoon the focus shifted from shutdowns to exploitation, with Asahi and Yomiuri reporting millions of attack attempts within hours of disclosure and confirmed hits on domestic servers. Yomiuri and Nikkei added Microsoft's finding that a China-linked group used AI to attack hundreds of organizations worldwide, while Capcom disclosed 11.77 million email addresses leaked.
Evening attention briefly moved to the NPB draft, with the Giants taking Yokohama High pitcher Oda Shoki and Nippon Ham selecting two-way Komoda Yosei.
