Rainbow Six Siege has suffered a major security breach that forced Ubisoft to take the game’s servers offline after hackers gained access to backend systems. The attack did not target individual players directly, but instead exploited internal infrastructure, allowing unauthorized manipulation of the game’s economy and moderation tools.
We're aware of an incident currently affecting Rainbow Six Siege. Our teams are working on a resolution.

We will share further updates once available.
As a result of the hack, players across all platforms suddenly received massive amounts of in-game currency, including billions of R6 Credits, along with rare and normally unobtainable cosmetic items. Some users also reported random bans and unbans, indicating that internal administrative systems had been compromised. The scale of the disruption quickly made the game unplayable, prompting Ubisoft to shut down Siege servers and the in-game marketplace to contain the damage.
Ubisoft has acknowledged the incident and confirmed it is actively investigating and restoring systems. The company stated that players will not be punished for spending any unauthorized credits received during the breach and that a full rollback of transactions made during the affected period will be carried out to stabilize the in-game economy. Servers are expected to return once Ubisoft confirms the exploit has been fully closed.
At this stage, there is no evidence that player account credentials, passwords, or personal data were stolen. The breach appears limited to server-side access rather than direct account hacking. However, since backend systems were compromised, the situation is still considered serious until Ubisoft completes its security review.
For now, players are advised to wait for official confirmation before logging b . ack in. While accounts do not appear to be directly at risk, enabling two-factor authentication and updating passwords is recommended as a precaution once services are fully restored. Ubisoft has promised further updates as the investigation continues
