Overview
- Rainbow Six Siege and its Marketplace were intentionally taken offline as Ubisoft investigates a compromise of in‑game systems across all platforms.
- Player reports and screenshots indicate attackers granted roughly 2 billion R6 Credits and unlocked developer‑only cosmetics, with a cash value estimated at about $13.33 million.
- Attackers also manipulated moderation tools to ban and unban accounts and display fake ban messages; Ubisoft noted the ban ticker had already been disabled and said a ShieldGuard ban wave was unrelated.
- Ubisoft confirmed a rollback of all transactions made after 11:00 AM UTC on December 27 and reiterated that players will not be punished for spending the windfall; services remained down as of December 28.
- Security researchers cited unverified claims of a wider breach via a MongoDB flaw affecting internal systems, which remain under investigation, and community figures urged players to stay offline and secure their accounts with password changes and 2FA.
