Suspension and restoration
After unauthorized access to a service it uses was discovered early on 9 November, Meijiza stopped online bookings/lookups and telephone meal reservations. The 13:00 update restored FamilyMart payment and issuance; a separate notice that day confirmed all functions restored. One advance-sale window would reopen at 10:00 on the 10th with an extended deadline. [1] [2]
The compromised operator, whether data leaked, fields and counts are not identified. Impact investigation continues, so restoration is not investigation completion. A system company named in general terms is not inferred to be the breached provider. [1] [2]
