Accidentally overwriting Yahoo personal information to another ID Up to approximately 390,000 cases August 6 23:47
Yahoo announced that there was a problem with the ID registration system, and personal information such as address and telephone number was accidentally overwritten with another ID.
The maximum number of potentially changed IDs is approximately 390,000.
According to the announcement, when a user with a Yahoo ID changes their personal information such as their name, address, and telephone number, the ID of another user is accidentally overwritten.
The problem was that between the 29th of last month and the 4th of this month, the maximum number of IDs that may have been changed was 387,000.
From the inquiry from the user, I found that the problem occurred on the 4th.
When I checked it at the company, I found that the cause was that the system was updated, and I restored the system to the original state, and now there is no malfunction.
The company asks the user to contact the user and re-enter the information that has been changed by mistake after deleting it.
This means that there are cases where the company reports that the ordered package has not arrived or the package ordered by another person has arrived.
Yahoo apologizes, "I apologize for the great inconvenience," and is working to prevent a recurrence.
