Nintendo

Nintendo confirmed a breach by the hacking group Crimson Collective, who accessed some of its external web servers. The company clarified that no sensitive data—such as development, business, personal, or payment information—was compromised. The breach was limited to public-facing systems, with no impact on user data or internal game assets. The attackers posted alleged proof online, including folders and files from the intrusion, but Nintendo affirmed that the incident did not expose critical or confidential information. The group is known for similar attacks, including a claimed breach of Red Hat, where they exfiltrated 570 GB of data. Their modus operandi involves breaching systems, stealing data, and attempting blackmail. Nintendo has historically pursued legal action against hackers, as seen in the 2024 Teraleak incident involving Game Freak’s Pokémon data. Users were advised to enable 2FA, update passwords, and avoid phishing attempts, though no direct harm to accounts was reported.
