19 Aug 2026 KDDI株式会社 (KDDI Corporation)KDDI: data protection authority guidance after leak of 12.2 million email credentials JapanData breaches and data security Reprimand or warning

Through a software vulnerability in a mail platform developed by KDDI and provided to several internet service providers, unauthorised parties obtained the credentials (email address and password) of 12,231,954 people; 7,616,173 passwords were stored in plain text, so mailboxes could be read (discovered on 17 June 2026). The authority gave KDDI guidance (shidō) under Art. 147 APPI to improve its technical security measures because access controls against attackers spreading through the system had been inadequate, required a report by 19 October 2026 and also gave such guidance to individual providers responsible for the plain-text storage.

What organisations can take from it

Passwords must never be stored in plain text, and platforms that serve many customers need layered defences against attackers spreading after a breach.
