Nintendo, the Japanese maker of the Wii game console and Super Mario games, says it was targeted in recent online data attacks, but that no personal or company information was lost.
Kyoto-based Nintendo Co. spokesman Ken Toyoda said on Sunday that the server of an affiliate of Nintendo's US unit was accessed unlawfully a few weeks ago, but that there were no damages. He declined to elaborate.
The damage from what could be a spate of hacking was more serious at rival Sony Corp.
Sony has said massive personal information is suspected of having been stolen after security was compromised for its network service for the PlayStation 3 game machine, for other online services and, in the past week, from Sony Pictures' website.
