Nintendo was recently subject to a hacking attempt on its US servers, the firm has admitted.
No services have been affected, and the company is at pains to stress that its customers' data remains safe.
"The server contained no consumer information. The protection of our customer information is our utmost priority. We constantly monitor our security," said Nintendo of America in a statement.
Hacker collective Lulzsec have admitted to being behind the incursion, but claimed on Twitter that "we didn't mean any harm."
Said Lulzsec in an earlier Tweet, "We're not targeting Nintendo. We like the N64 too much - we sincerely hope Nintendo plugs the gap." The hackers later confirmed that Nintendo had closed the security hole in question.
The group is also responsible for exploiting vulnerabilities in a number of Sony sites, and has previously claimed that "this is the beginning of the end for Sony."
