Rainbow Six Siege Hack Forces Ubisoft to Shut Down Servers and Roll Back Progress

Ubisoft temporarily shut down Tom Clancy’s Rainbow Six Siege after a serious security incident disrupted live servers and affected player accounts across several platforms. The publisher suspended online services and began emergency maintenance once it became clear that in-game systems had been altered without authorization. Ubisoft confirmed that the issue required immediate action to protect Siege’s economy and competitive environment.

Players first noticed the problem when accounts suddenly received large amounts of in-game currency and cosmetic items unlocked without purchase. Others reported unusual ban messages appearing in public feeds and match histories. As screenshots and clips spread across social media and community forums, Ubisoft acknowledged the situation and took Siege offline to stop further damage, as reported by PC-Spieler.

What Ubisoft Confirmed About the Incident

Ubisoft stated that attackers exploited a weakness in Siege’s backend services rather than using traditional cheat software installed on player systems. The exploit allowed unauthorized changes to account inventories and moderation tools. Because the issue occurred server-side, affected players had no way to avoid or prevent the impact once the exploit went live.

To contain the situation, Ubisoft disabled several live services and initiated a full rollback. This process aimed to reverse all changes made during the affected time window, including currency grants, item unlocks, and moderation actions. According to IGN, Ubisoft confirmed that players would not face penalties for items or currency received as a result of the incident.

Impact on Servers, Progress, and Competitive Play

The hack disrupted matchmaking, ranked play, and the in-game store, forcing Ubisoft to suspend Siege’s live environment while engineers worked to stabilize affected systems. Some players reported missing or altered inventories after logging in during the incident window, while others could not connect at all once servers went offline.

Ubisoft warned that any progress made during the affected period might be reversed as part of the rollback process. The publisher advised players to avoid making purchases or inventory changes until services fully stabilized. As The Verge noted, restoring trust in Siege’s in-game economy became a top priority during the recovery.

Account Security and Player Safety

Ubisoft addressed concerns about personal data by stating that it found no evidence of leaked passwords or compromised personal information. The company clarified that the exploit affected game services and backend systems, not account credential storage or payment data.

Even so, Ubisoft encouraged players to enable two-factor authentication and remain alert for unusual account activity. Large-scale service incidents often lead to increased caution across live-service games, especially when server-side vulnerabilities are involved.

What Comes Next for Rainbow Six Siege

Ubisoft has brought Siege servers back online in stages while continuing to monitor for abnormal behavior. The company said it deployed additional security checks and began a broader review of the systems involved in the incident. Ubisoft has not shared deeper technical details but stated that further updates will follow if needed.

The incident highlights the risks faced by long-running live-service games that rely on centralized backend systems. For Rainbow Six Siege, Ubisoft’s response and transparency now matter as much as the breach itself. How the publisher strengthens its infrastructure will remain under close watch from players and the wider PC gaming community.
