A hacker group known as Crimson Collective claims to have breached Nintendo’s internal systems and stolen approximately 570 GB of company data. Nintendo has not confirmed the breach, and no evidence of compromised customer data has emerged.
Details of the Alleged Breach
The hacking group Crimson Collective posted a screenshot on October 11, 2025, showing what appears to be internal Nintendo file directories. The image displays folders labeled with names such as production assets, developer previews, admin files, and stress test data.[1][2][3]
Cybersecurity monitoring account Hackmanac reported the claim on social media. The group accompanied their post with the statement, “Who said we do not have Nintendo topic files?”[4][5]
The alleged data volume of 570 GB has not been independently verified. No leaked files have surfaced publicly as of October 11, 2025.[6]
Who Is Crimson Collective
Crimson Collective gained attention in early October 2025 after claiming responsibility for breaching Red Hat’s GitHub repositories. Red Hat confirmed that incident on October 2, 2025, and stated it had contacted law enforcement.[7]
The group also allegedly attacked Claro Colombia in September 2025, claiming to have stolen customer invoices and financial records.[8]
In September 2025, Crimson Collective was credited with defacing Nintendo’s website, though details of that incident remain limited.[9]
Nintendo’s Response and Data Security
Nintendo has not issued a public statement regarding the alleged breach as of October 11, 2025. The company has not confirmed whether any systems were compromised.[10]
There is currently no indication that player accounts, personal information, or payment data were accessed in this alleged incident. The claims focus exclusively on internal company files.
Past Nintendo Security Incidents
Nintendo experienced the Gigaleak between 2018 and 2020, when source code and development materials for games including Pokemon and The Legend of Zelda were leaked online.
In 2020, the Nintendo Network ID system was breached, affecting over 300,000 user accounts.
Broader Cybersecurity Context
Major gaming companies have faced increased targeting by hacker groups. Rockstar Games suffered a significant breach in 2022 that resulted in early footage of Grand Theft Auto VI being leaked.
Game Freak, a Nintendo development partner, experienced intrusions that exposed Pokemon development documentation.
Last week, Discord notified users that a third party customer service platform had been compromised, exposing some user personal data including government identification documents.
