Miura: network intrusion

An August 14 intrusion through an overseas group company disrupted some services. August's notice identified 161,383 trade entries and 5,537 individual-customer shipping entries, among other datasets, as potentially exposed; these are records, not people. The May 2026 final report identified leakage or possible leakage of 5,021 group-staff records, including business contacts and passwords. No secondary harm was confirmed.
