Unauthorized login damage with Nintendo Network ID

Nintendo revealed on April 24 that an unauthorized login to the "Nintendo Network ID" [hereinafter NNID] occurred.

Unauthorized login is due to a password list attack using login IDs and passwords that were obtained illegally from services other than the company's. It seems that an attack occurred around the beginning of April and spoofing logins were being performed.

NNID is an ID for using services for Nintendo 3DS series and Wii U. Although it is different from the Nintendo account, the company has abolished the linkage function because it can be linked. If you use a common password, you may be able to log in to your Nintendo account, so you will be required to reset your password.

About 160,000 NNIDs received unauthorized login. Information that may have been viewed by a third party includes nickname, date of birth, country / region, and email address. If you are linked to a Nintendo account, your registered name, date of birth, gender, country / region, and email address.

The company urges users not to reuse the same password when resetting their password, including other external services. Two-step authentication can be set for Nintendo accounts, so I would like to introduce it.
