Nintendo yesterday confirmed that an additional 140,000 Nintendo Network IDs were breached back in April 2020, bringing the total number of compromised accounts to 160,000.
“We posted a report on unauthorized login on April 24th, but as a result of continuing the investigation after that, there were approximately 140,000 additional NNIDs that may have been accessed maliciously. It turned out that it was. We have also reset the passwords for these 140,000 NNIDs and the Nintendo accounts that were linked with them, and contacted the customer separately. At the same time, we are taking additional security measures,” Nintendo advised.
“Less than 1% of all NNIDs around the world that may have been illegally logged in may have actually been fraudulently traded through their Nintendo account. We are still in the process of refunding in each country, but we have already finished refunding for most customers.”
All Nintendo Switch users are recommended to enable and use two-factor authentication to secure their accounts.
