A prominent hacker organization has reportedly executed a significant data breach against Nintendo, potentially exposing sensitive details regarding future game releases. As 2025 progresses, Nintendo has seen substantial activity with the anticipated Switch 2 and exclusive titles, including Mario Kart World, Donkey Kong Bananza, and the forthcoming Pokémon Legends: Z-A.
Information shared by Twitter user Hackman (via Game Rant) indicates that the hacker group Crimson Collective claims to have extracted over 570 gigabytes of confidential data from Nintendo. While there is presently no evidence that personal data of employees has been compromised, if the allegations are validated, this breach could be among the most critical crises faced by Nintendo.

Over 570 GB of Data Potentially Compromised
Allegations shared on social media reportedly outline the various data folders accessed during this breach. Categories mentioned include game assets, production timelines, and stress test documentation. The statements from Crimson Collective imply that they possess sensitive information related to upcoming Nintendo titles.
This is not the first instance of Crimson Collective claiming a breach against Nintendo. The group also took responsibility for defacing Nintendo’s website in September 2025, coinciding with their reported intrusions into private GitHub repositories utilized by various clients like Red Hat and Claro Colombia.
Nintendo Has Experienced Data Breaches Previously
Game Freak, Developer of Pokémon, Experienced Significant Data Leaks
Nintendo has previously faced numerous major security breaches, with a significant incident involving Pokémon developer Game Freak being particularly noteworthy. Known as the “Teraleak,” the massive hack from October 2024 resulted in the leak of data regarding Pokémon Legends: Z-A, alongside insights into potential Generation 10 Pokémon titles, including unreleased designs and lore concepts.
In the spring of 2020, Nintendo acknowledged that approximately 160,000 Switch accounts were compromised, placing sensitive personal information at risk. Fortunately, credit card data remained secure, though details such as usernames, birth dates, regional information, gender, and email addresses were exposed.
As of now, there is no official confirmation regarding the recent Nintendo data breach or the involvement of Crimson Collective. However, further updates are anticipated as the situation develops.
