Ubisoft has brought Rainbow Six Siege back online after a massive exploit wreaked havoc on player accounts, in-game currency, and backend systems.

- The game is now live again, though long login queues persist and the in-game Marketplace remains closed.
What Happened?
A strange and large-scale cyberattack hit Rainbow Six Siege late December, leading to chaos in the game’s systems. The breach injected billions of R6 Credits into accounts, unlocked rare developer-only cosmetics, and randomly banned or unbanned players. Ubisoft responded by shutting down the game globally and initiating a full rollback to restore order.

Ubisoft’s Response to the Chaos
Ubisoft quickly acknowledged the breach on social media and took the game offline on December 27. The attack led to:
- Unexpected in-game currency spikes in player accounts.
- Unlocked rare and developer-only skins.
- Random account bans and reversals.
- Backend system disruptions.
In its update, Ubisoft assured players that they would not be punished for spending any of the illicitly received credits. Instead, the company focused on restoring balance by rolling back transactions to their pre-breach state.
“Our live tests are now complete and we are opening the game to all players,” Ubisoft announced on X. “Please note that you may experience a queue when connecting, as our services ramp up.”

The Rollback and Recovery
Ubisoft conducted a full rollback of player data to revert inventories and transactions made after the incident. According to the company:
- Players who did not log in between December 27 and December 29 will see no changes to their inventories.
- A small number of players may temporarily lose access to certain owned items.
- Investigations and inventory corrections will continue for at least two weeks.
The rollback was carried out with “extreme care,” and Ubisoft emphasized the importance of quality control to avoid further data corruption or account issues. However, as of now, many users still face long login queues, with some claiming wait times up to 24 hours.
The Marketplace and Server Status
While the main game is back online, Ubisoft confirmed that the Rainbow Six Siege Marketplace will remain closed until further notice. This suggests that backend security audits are still underway, likely due to the nature of the breach.
At the height of the chaos, estimates showed that around 2 billion R6 Credits, valued at over 13 million dollars, were injected into accounts. The breach raised serious questions about Ubisoft’s backend security, with researchers suggesting that weak API authorizations may have been exploited.
As of now, Ubisoft has not confirmed the exact cause of the hack but stated that server restoration is its top priority.
SQ Magazine’s Takeaway
I’ve seen my fair share of online game meltdowns, but this Rainbow Six Siege situation was on another level. Players woke up with billions in-game, others got banned out of nowhere, and everything felt like a digital riot. While Ubisoft acted fast, the fact that this could happen points to deeper problems in how game infrastructures are secured. If you’re a Siege player, change your password and keep an eye on your account. And yeah, maybe avoid the Marketplace for a while.
