It was back in April when Nintendo, a Japanese video game company,?revealed?a
major data breach where about 160,000 accounts of Nintendo Switch users were
compromised. Now, the video game giant hasconfirmed
[https://www.nintendo.co.jp/support/information/2020/0424.html#20200609]that
more number of users were affected by the breach than previously known, bringing
the total number of breached user accounts to 300,000.

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?, mentioned Nintendo in
its updatedblog post
[https://www.nintendo.co.jp/support/information/2020/0424.html#20200609]. ?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?.

With the surge in popularity of Nintendo Switch among users, these accounts
became more vulnerable to hack attacks as more hackers started to target them.
Personal data of users that got compromised included date of birth, and email
addresses. Nintendo added in the blog post that ?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?.

The security vulnerability was found to exist when users linked their Nintendo
3DS and Wii U?s Nintendo Network ID (NNID) with their Nintendo Switch. Following
which the company abolished the function to log in to a Nintendo account via
NNID. It also added an extra security step where password resets are to be
performed sequentially for NNIDs and Nintendo accounts that may have been
illegally logged in.

?We deeply apologise for causing trouble and worries to customers,? Nintendo
said in itsstatement
