Rainbow Six Siege undergoes emergency shutdown after a massive attack on the credit system

Ubisoft faced a serious security crisis when unidentified hacker groups gained access to the administrative internal systems of Rainbow Six Siege. As a result of the incident, 2 billion premium credits were transferred to player accounts, representing a potential loss of approximately $13.3 million. The attack occurred on December 26, 2025, affecting over 34,000 active platform users daily.

Scale of the attack and Ubisoft's immediate response

The injections included not only in-game currency but also developer resource skins, Alpha Packs, and spontaneous account bans. The breach involved systems on PC, Xbox, and PlayStation simultaneously, disrupting the normal functioning of the title. Ubisoft decided on a radical step — suspending Rainbow Six Siege servers on all platforms on December 27.

The game development team announced a recovery strategy, restoring account states from 11:00 UTC without imposing sanctions on players who illegally distributed the funds. Ubisoft's statement emphasized:

“We are currently restoring previous states, followed by comprehensive quality control tests to ensure the security and integrity of accounts.”

Restoration and control tests

Currently, Rainbow Six Siege is undergoing limited functionality testing with a selected group of players. The full schedule for restoring access remains uncertain, as the audit of the entire internal infrastructure is still ongoing. Ubisoft has not provided specific dates, focusing instead on the quality of the recovery procedures.

This situation highlights a fundamental difference between centralized game systems and true decentralization. In the case of Rainbow Six Siege — as with many titles — the service provider can fully revoke transactions and alter account states. Even cryptocurrency projects like the Flow blockchain have demonstrated similar capabilities in the past, showing that true immutability is rarer than it seems.

Industry security context

Ubisoft actively invests in the Web3 space, collaborating with Immutable to implement blockchain infrastructure for titles like Might & Magic. Meanwhile, the cryptocurrency sector faces its own security challenges — 某 exchange recently experienced a breach resulting in the loss of about $37 million worth of tokens. The platform responded with a comprehensive user support plan, implementing new security protocols.

The Rainbow Six Siege incident serves as a reminder that, regardless of industry — gaming or cryptocurrencies — central access points remain potential targets for advanced attacks. Ubisoft's current priority is fully restoring game functionality and regaining the trust of the gaming community.
