Overview
- Attackers gained access to backend tools on December 27, triggering fake ban-ticker messages, random bans and unbans, unlocking all cosmetics, and crediting accounts with approximately 2 billion R6 Credits and Renown.
- Ubisoft intentionally shut down Rainbow Six Siege and its Marketplace, confirmed a rollback of all transactions from 11:00 UTC on December 27, and said players would not be punished for spending the illicit credits.
- Following testing, Ubisoft completed the rollback and brought servers back online via a soft launch before fully reopening, warning that login queues may occur as services scale up.
- The rollback applies to players who logged in between December 27 at 10:49 UTC and December 29, and a small percentage may temporarily lose access to some owned items while fixes are applied over the next two weeks.
- The Marketplace remains closed during the investigation, and separate third‑party claims of a broader Ubisoft breach via a MongoDB flaw and possible source code or data theft remain unverified.
