"The server contained no consumer information. The protection of our customer information is our utmost priority," said Nintendo of America, the U.S. branch of Nintendo, in an e-mailed statement to Reuters. "We constantly monitor our security."
Lulzdec twittered, "Re: Nintendo, we just got a config file and made it clear that we didn't mean any harm. Nintendo had already fixed it anyway. <3 them." On the hacker group's official site, "Considering fun is now restricted to Friday, where we look forward to the weekend, weekend, we have now taken it upon ourselves to spread fun, fun, fun, throughout the entire calender (sic) year."
Considering Nintendo doesn't hold user information - forcing gamers to repurchase items when they want to re-install - there was probably nothing Lulzsec actually wanted.
