According to news recently posted online by well-known content creator Nintendo Prime, Nintendo may be taking measures to investigate the source of internal leaks. Previously, a large number of rumors related to Nintendo's unannounced projects have appeared online, including details about upcoming games for the Switch 2.
Nintendo Prime said: "I have learned from 7 (yes, 7) different sources that Nintendo has officially launched the method of 'spreading false information internally' in an attempt to identify the leaker." This method is often called the "canary trap," and the specific operation is to distribute false information with slightly different details to different internal departments to trace the source of the leak.

He added that this is not the first time Nintendo has used such tactics, saying: "This is not the first time they have done this." It is unclear whether this move is a direct response to recent leaks or whether it is part of the company's regular internal management, but the news indicates that control of information flow within Nintendo may be further tightened in the short term.
This statement was echoed by other industry insiders, including Reese Riley, who runs the "Kiwi Talkz" channel, who said: "Yes, Nintendo and Rockstar are using this strategy." He also said that this is a very common operation for large companies that need to handle sensitive product information.
Previously, a major leak revealed purported details of multiple unannounced projects from Nintendo, including a new "Star Fox" series and a possible remake of "The Legend of Zelda: Ocarina of Time" in development, which also intensified speculation about Nintendo. None of these reports have been confirmed so far, and Nintendo has not issued any official comment on this leak or the internal response measures reported online.
If the news spread online is true, such control measures are likely to lead to fewer reliable leaks in the future - when high-profile product information is leaked in advance, companies often take action to strengthen internal controls.
