The mail password was fifty-four thousand

Fifty-four thousand mailboxes. The password is in this one.

The So-net member book, as of today’s notice, did not take the login password. Four leftover mail products did. Mail service (G) — the old GyaO domains: 24,655, free. A-Box extra mailboxes on so-net.ne.jp: 17,672, paid. VAIO mail: 7,005. PostPet: 5,069. Total 54,401 addresses plus the mailbox password. The company reset those passwords today and is telling people to set a new one in My Page.

This is not 2.58 million passwords. It is four old products that still issued a mailbox. A So-net member who never held one of those four is in the member book and out of this file. A leaver from March who still had the VAIO box is in both.

They have stood up a desk. They have not confirmed secondary use as of this evening. The next mail that already knows the old GyaO address and asks you to “confirm the ISP password” is someone else.

What 54,401 will be asked to cover

It will be briefed as every So-net password. It is 54,401 mailboxes on four leftover services. It will be briefed as the 2.58 million. That number is the member book from this morning’s other sentence. Do not add them. The mailbox password is the one that still opens something.

If you are in the 54,401, the reset they did today is the incident. If you are only in the member book, you do not have a So-net mailbox password in this take. A reuse of that mailbox password on another site is your problem, not their count.

Fifty-four thousand is a mailbox slice. The password is the part that keeps working after the member file looks like “no passwords.”
