Overview

• Asahi and investigators are treating the breach as ransomware, with experts reporting traces that suggest a possible unauthorized transfer of data.
• Most of the brewer’s roughly 30 domestic factories have halted output after ordering and shipping systems were disabled, though handwritten orders and limited emergency shipments have begun.
• Major retailers including 7‑Eleven, FamilyMart and Lawson have posted notices and warned customers that Asahi beer and other beverages could run short within days.
• The company says the disruption is confined to Japan, with European and UK manufacturing and supplies operating normally.
• Asahi has delayed planned product launches, works with external cyber specialists and police, and has not provided an estimate for full restoration as its shares fall over the week.
