The change history was the file

The church opened the pile. It authenticated one folder.

After KISA’s call yesterday, Yoido Full Gospel Church said it went through the suspected material with an outside firm and that one of seven sets, titled “Member Information Change History,” holds personal information. Names and dates of birth for 850,000 members. With those, 2,629 records of changes to resident registration numbers, 3,964 records of phone-number changes, and 7,202 records of address changes. At 1 a.m. they had already cut external access and rotated server passwords. Today’s sentence is the first one that names a file they are willing to own.

Oasis Security’s server-side count is still larger: about 960,000 member records, about 330,000 donation records, tens of thousands of approval documents, and thousands of internal chats, taken, in the firm’s telling, through a web shell on the ERP box. The church has not, in the account published today, confirmed the donation ledger or the messenger archive. One confirmed set out of seven suspected sets is a scope statement. It is not a finding that the other six are empty, and it is not a finding that they are full.

What 850,000 will be asked to mean

It will be briefed as “the whole membership database.” What they confirmed is a change log: who you are, when you were born, and the edits to the legal identity number, the phone, and the address. A change to a resident registration number is a smaller count than 850,000 and a worse fact than a birthday. The birthday tells a stranger which member. The changed legal number tells them the member tried to correct the key, and shows them the old one and the new one if both are in the history.

If your row is only a name and a date of birth, say that. If your row is one of the 2,629, the 3,964, or the 7,202, say that louder, and assume a phone or an address that used to be current is now a way to reach you or to impersonate the correction. Do not pay anyone offering to delete the church’s file. The confirmed copy is already in an investigation. A stranger does not have the only one.

The firm’s 960,000 was a belief about a server. The church’s 850,000 is a file it read. Keep them in different sentences.
