Ubisoft Breach: Investigating claims of a Wider Attack Beyond Rainbow Six Siege
If you possess any facts concerning this incident, or any other unreported security breaches, you can confidentially reach out to us via Signal at 646-961-3731 or email us at tips@bleepingcomputer.com.
Recent events have brought Ubisoft’s security into question, sparking rumors of a considerably larger breach than initially acknowledged. While Ubisoft has confirmed an in-game abuse issue within Rainbow Six Siege,unverified reports suggest a more extensive compromise of their infrastructure. let’s break down what we know, what’s being claimed, and what it means for you.
The Initial Incident: Rainbow Six Siege Abuse
Ubisoft has publicly stated that an unauthorized party exploited a vulnerability to manipulate bans and in-game inventories within Rainbow Six Siege. Importantly, they’ve confirmed this incident did not involve access to user data.
Emerging Claims: A Potential multi-Group Breach
Security research group VX-Underground has brought forth claims from multiple threat actors, alleging a far broader scope to the attack. These claims center around a MongoDB vulnerability known as “MongoBleed” (CVE-2025-14847).
This flaw is especially concerning as it allows attackers to potentially leak sensitive information – including credentials and authentication keys – from exposed MongoDB instances without needing authentication. A proof-of-concept (PoC) exploit is already publicly available, actively searching for secrets within vulnerable servers.
Here’s a breakdown of the allegations made by different groups, as reported by VX-Underground:
* One group asserts they exploited a Rainbow Six Siege service to manipulate bans and in-game items, explicitly stating no user data was accessed.
* A second group claims to have leveraged MongoBleed to gain access to Ubisoft’s internal Git repositories. They allege stealing a considerable archive of source code spanning from the 1990s to the present day.
* A third group alleges they successfully stole Ubisoft user data through MongoBleed and are currently attempting to extort the company for a ransom payment.
* A fourth group challenges some of these claims, suggesting the second group had prolonged access to Ubisoft’s source code prior to any recent events.
What Dose MongoBleed Mean for you?
MongoBleed is a serious vulnerability. If exploited, it could expose sensitive data stored within a mongodb database. This data could include usernames, passwords, API keys, and other critical information. For Ubisoft, this could mean compromised internal systems and potentially, user data.
Verification Status: Proceed with Caution
Currently, BleepingComputer has been unable to independently verify any of these claims. This includes confirmation of MongoBleed exploitation, source code access, or user data theft. It’s crucial to understand that these remain allegations at this time.
We are actively monitoring the situation and will provide updates as more information becomes available. Ubisoft has only publicly confirmed the Rainbow six Siege in-game abuse. ther is currently no public evidence supporting a wider breach.
staying informed
This is a developing story. BleepingComputer will continue to investigate and provide updates as Ubisoft releases further details or as we independently verify these claims.We are committed to keeping you informed about the evolving security landscape and potential risks to your data.
