Ubisoft's online game Rainbow Six Siege faced significant disruptions due to a security breach that resulted in unauthorized in-game transactions for players. The incident led to the server shutdown on December 27, 2025, affecting users across PC, PlayStation, and Xbox platforms. Players reported discrepancies in their accounts, with some seeing either inflated credits or bans.
On December 29, the company announced the completion of a transaction rollback and the reopening of game servers, though the Marketplace remains inaccessible. Players who accessed the game between December 27 at 10:49 UTC and December 29 were assured they wouldn't face bans for using gained credits. Ubisoft emphasized the need for thorough quality control tests to maintain account integrity.
Initially, the company acknowledged the issue on social media early Saturday and began addressing it promptly. Despite the rollback and server restoration, Ubisoft warned that users might experience delays due to the high volume of players reconnecting.
