Rainbow Six Siege Servers Taken Offline After Hack

• Hackers gained control of key Rainbow Six Siege systems, handed every player 2 billion R6 Credits and unlocked all items. • Ubisoft shut down the game's servers and in-game marketplace while it investigates; some transactions will be rolled back. • Ubisoft says players won't be punished for spending credits received, but it will revert transactions after 11:00 AM UTC on Saturday. • The injected 2 billion R6 Credits have an estimated retail value of roughly $13.33 million.

What happened

On Dec. 28, 2025, Ubisoft confirmed on X (formerly Twitter) that Rainbow Six Siege had been compromised and that it had taken the game’s servers and marketplace offline while it addressed the issue.

According to Ubisoft and security reports, attackers gained control over substantial portions of the game's backend. They used that access to ban and unban users, push custom messages to the ban ticker, unlock all in-game items, and credit every account with 2 billion R6 Credits and unlimited Renown.

How big is the impact?

Ubisoft sells R6 Credits in its store—15,000 credits cost $99.99—so the 2 billion credits issued in the exploit translate to an approximate retail value of $13.33 million. Beyond direct monetary figures, the incident undermines the integrity of in-game progression, cosmetics, and the Siege marketplace.

Players reported seeing unlocked cosmetic items and balance changes, while Ubisoft temporarily disabled services to prevent further abuse.

Ubisoft's response and rollback policy

Ubisoft said it will not punish players for spending any credits they received during the breach. However, the publisher announced it will roll back any transactions made after 11:00 AM UTC on Saturday (6:00 AM ET) to limit fraud and abuse of the compromised systems.

The company has kept the servers and marketplace offline as it investigates and secures affected systems. Ubisoft has also stated it is engaging its security teams to determine the breach's scope and prevent recurrence.

Player guidance and best practices

Players should avoid attempting to exploit the situation by trading or cashing out items gained during the incident. Even if Ubisoft says users won’t be punished, rolled-back transactions could lead to lost items or currency.

Keep an eye on official channels—Ubisoft's X account and support pages—for recovery timelines and instructions. Back up any account information and monitor email for communication from Ubisoft about account security steps or required password resets.

Wider implications

The incident highlights persistent risks in live-service games where virtual economies have real-world value. Publishers like Ubisoft must balance rapid incident response with transparent communication to protect players and preserve trust.

Ubisoft has been contacted for further comment; the company’s public posts remain the primary source of confirmed details while the investigation continues.
