The Crimson Collective hacking group claims to have breached Nintendo's security and stolen files from the gaming company.
A high-profile hacking group called Crimson Collective claimed that it had successfully hacked Nintendo, which is notorious for being litigious and overprotective of its intellectual property. Cybersecurity intelligence firm Hackmanac shared a screenshot on X that allegedly showed proof of the attack, with folders that seemingly stored Nintendo data, including production assets, developer files, and backups. However, the Japanese gaming giant is yet to make a statement about this attack, so we’re unsure if this is real or just a made-up screenshot.

Crimson Collective is the group behind the recent attack on Red Hat, during which it gained unauthorized access to the company’s GitHub repositories and stole about 570GB of data. The group then attempted to extort the company but was simply dismissed. Red Hat eventually confirmed the breach, opting to work with the authorities to pursue the attackers and collaborating with its affected clients to rectify the issue.

If this attack on Nintendo is legitimate and perpetrated by the same party, then it’s likely they are attempting the same tactic of contacting the gaming giant through official channels and asking for payment to delete the stolen data, or else they will leak it.

This isn’t the first time that hackers have attacked a gaming company. Rockstar was previously targeted by an attack in 2023, and some of the source code for Grand Theft Auto VI was leaked online. In the same year, Insomniac Games, the studio behind several Spider-Man titles, was hit by a ransomware attack, and files related to games and employees were made available for download on the internet. CD Projekt Red was also a victim in 2021, after the source codes for Cyberpunk 2077, The Witcher 3, and several other titles, along with several different files, were stolen and threatened to be released publicly if the company did not pay.

Despite all the noise, Nintendo is known for keeping its secrets. Unless customer or personal data has been targeted or leaked, where it’s required by law to notify the public of an attack, it’s unlikely that the company will disclose any details of this breach. So, without confirmation from the makers of the Switch 2, we can only guess if Crimson Collective’s exploit is true or not.

We are writing to provide an update regarding a security incident related to a specific GitLab environment used by our Red Hat Consulting team. Red Hat takes the security and integrity of our systems and the data entrusted to us extremely seriously, and we are addressing this issue with the highest priority.

What happened
We recently detected unauthorized access to a GitLab instance used for internal Red Hat Consulting collaboration in select engagements. Upon detection, we promptly launched a thorough investigation, removed the unauthorized party’s access, isolated the instance, and contacted the appropriate authorities. Our investigation, which is ongoing, found that an unauthorized third party had accessed and copied some data from this instance.

We have now implemented additional hardening measures designed to help prevent further access and contain the issue.

Scope and impact on customers
We understand you may have questions about whether this incident affects you. Based on our investigation to date, we can share:

Impact on Red Hat products and supply chain: At this time, we have no reason to believe this security issue impacts any of our other Red Hat services or products, including our software supply chain or downloading Red Hat software from official channels.
Consulting customers: If you are a Red Hat Consulting customer, our analysis is ongoing. The compromised GitLab instance housed consulting engagement data, which may include, for example, Red Hat’s project specifications, example code snippets, and internal communications about consulting services. This GitLab instance typically does not house sensitive personal data. While our analysis remains ongoing, we have not identified sensitive personal data within the impacted data at this time. We will notify you directly if we believe you have been impacted.
Other customers: If you are not a Red Hat Consulting customer, there is currently no evidence that you have been affected by this incident.
For clarity, this incident is unrelated to a Red Hat OpenShift AI vulnerability (CVE-2025-10725) that was announced yesterday.

Our next steps
We are engaging directly with any customers who may be impacted.

Thank you for your continued trust in Red Hat. We appreciate your patience as we continue our investigation.
