Ubisoft, the publisher behind the long-running tactical shooter Tom Clancy’s Rainbow Six Siege, has suspended the game’s online services after a major cybersecurity incident that saw hackers distribute a vast number of in-game tokens across player accounts. The breach has forced the company to take unprecedented action, including shutting down servers, disabling the in-game marketplace, and initiating extensive rollbacks to undo the effects of the intrusion.

This event has left the gaming community shaken as both casual and competitive players grapple with its implications. The incident has also reignited discussions about online game security and digital economies. The details of what occurred, how Ubisoft is responding, and what players can expect next are explored below.
A Sudden Surge of Free Currency
On December 27, 2025, thousands of Rainbow Six Siege players began reporting something unusual: millions, and in many cases billions, of R6 Credits, Renown, and exclusive cosmetic items showing up in their accounts without explanation. This premium in-game currency is normally purchased with real money; for example, 15,000 R6 Credits retail for $99.99 USD. (KuCoin)
According to multiple reports, hackers managed to exploit Ubisoft’s backend systems, granting approximately 2 billion R6 Credits to each account. Valued at roughly $13.3 million USD per player at standard pricing, the scale of the distribution is unprecedented in the game’s history. (Cointelegraph)
As a result of the breach, players saw:
- Massive, unauthorized credit balances
- All cosmetic items — including ultra-rare skins — unlocked
- Unanticipated bans and unbans
- Messages appearing in moderation feeds that were not sent by Ubisoft systems
These effects spread across PC and console players, creating confusion and concern within the community. (Dexerto)
How Ubisoft Responded
Barely hours after the exploit began circulating, Ubisoft issued a public acknowledgement that something was wrong. Via its official Rainbow Six Siege account on X (formerly Twitter), the publisher confirmed its teams were investigating an active incident affecting the game’s services. (Dexerto)
Within a short timeframe, Ubisoft made two crucial decisions:
- Suspension of All Game Servers and Marketplace Operations
Ubisoft temporarily took Rainbow Six Siege offline across all platforms — PC, PlayStation, and Xbox — to halt further effects of the breach and prevent additional manipulation of the in-game economy. (GenerationAmiga.com) - Rollback of Transaction Records
The company announced that all in-game transactions logged after 11:00 AM UTC on December 27 would be rolled back, effectively removing unauthorized purchases or spending that resulted from the hack. Ubisoft assured players that no one will be penalized for spending credits they received during the incident. (NewsBytes)
At the time of writing, the game remains offline as Ubisoft works to restore services and verify the rollback process. There is no confirmed timeline for service restoration. (Reddit)
Technical Details and Speculations
While Ubisoft has not fully disclosed the precise vulnerability exploited by the hackers, cybersecurity research groups and third-party reporting suggest that a flaw known as MongoBleed — a vulnerability affecting database systems — may have played a role. The alleged exploit may have allowed unauthorized access to internal services, granting attackers administrative privileges. (Rescana)
Players also report seeing manipulation of moderation systems, including fake ban messages displayed during matches — though Ubisoft later clarified that the ban ticker was disabled in a previous update and that fake messages came from the attack itself, not Ubisoft’s systems. (Dexerto)
Regardless of the exact method, what is clear is that attackers were able to interact with backend tools normally reserved for developers, indicating a potentially serious breach of internal infrastructure. (Rescana)
Community Impact and Player Reactions
Across social platforms, players have expressed a mix of confusion, amusement, and concern. Some community members shared screenshots of their inflated currency balances, while others experienced sudden bans or restored accounts without explanation. (Reddit)
One recurring community theme is the tension between an influx of free content and the potential long-term impact on player trust. Although Ubisoft has promised not to punish legitimate players for the unexpected credits, many veterans caution against spending them until services are fully restored and account states have stabilized.

Professional streamers and influencers have also weighed in, noting that a flood of free currency and rare items could disrupt the in-game market and erode the value of items that players spent real money to obtain. (Dot Esports)
Broader Implications for Online Game Security
This incident is part of a wider pattern of cybersecurity challenges facing live-service games. As popular titles increasingly rely on online services, digital economies, and persistent player data, the potential attack surface expands. When backend systems are compromised, consequences can range from economic disruption to reputational harm.
Industry analysts are already observing that a breach of this scale will likely prompt developers and publishers alike to re-examine security protocols for internal tools, API access, and database configurations. Third-party reporting suggests the possibility of code or credential leaks, although this remains speculative until verified by Ubisoft. (Breached Company)
Ubisoft’s Official Statements
Ubisoft’s public responses have been consistent:
- Teams are actively investigating the incident
- Servers and the marketplace remain offline until resolution
- A rollback of unauthorized transactions is underway
- Players will not be punished for unintended credit gains
These statements have been shared across Ubisoft’s support channels and gaming news outlets. (Dexerto)
What Players Should Do Now
For players affected by the outage or considering logging back into the game once services return, the safest steps include:
- Avoid spending unauthorized credits until Ubisoft completes the rollback
- Monitor official Ubisoft accounts for updates on server status
- Check account transaction histories after rollback completion
- Enable two-factor authentication (2FA) if not already set up
Staying informed is critical, as Ubisoft will likely post further guidance and updates as part of its recovery process. (NewsBytes)
Final Thoughts
This breach — resulting in roughly $13.3 million in unauthorized in-game tokens distributed across player accounts — represents one of the most disruptive cybersecurity events Rainbow Six Siege has ever faced. The suspension of online services and ongoing rollback underscore not only the severity of the incident but also the fragility of digital economies in live-service games. (KuCoin)
As Ubisoft works to restore stability, the gaming community and industry at large will be watching closely. For now, players are advised to stay patient, heed official announcements, and prepare for the eventual return of one of the gaming world’s most enduring tactical shooters.
