Resolution Criteria

This market resolves YES if Rainbow Six Siege experiences another confirmed security breach or hack after the December 27, 2025 incident that results in unauthorized access to game systems, player accounts, or backend infrastructure. The breach must be publicly acknowledged by Ubisoft or verified by credible cybersecurity sources (e.g., BleepingComputer, security research groups, official CVE disclosures).

Resolution sources: Official Rainbow Six Siege X account announcements, Ubisoft's official security statements, or established cybersecurity news outlets.

The market resolves NO if no such breach occurs before the specified resolution date.

Background

Rainbow Six Siege suffered a breach that allowed hackers to abuse internal systems to ban and unban players, manipulate in-game moderation feeds, and grant massive amounts of in-game currency and cosmetic items to accounts worldwide. Rainbow Six Siege services were restored on December 29, 2025. Ubisoft confirmed there is no evidence of stolen account credentials or leaked personal information from this incident. A second round of outages came only a week after the first, though the severity was less than the initial breach.

Considerations

Ubisoft faces dual security crises as outsourced helpdesk staff have been accepting bribes for panel access since 2021. This incident underscores the growing importance of proactive security audits as live-service games age and internal systems become increasingly complex.

I'll search for the most current information about the Rainbow Six Siege security incidents to ensure the description is accurate and up-to-date.Based on my research, I can now provide an updated description. The search results confirm the December 27, 2025 incident and reveal a second breach occurred in early January 2026. Here's the refined description:

Resolution Criteria

This market resolves YES if Rainbow Six Siege experiences a confirmed security breach or hack after December 27, 2025 that results in unauthorized access to game systems, player accounts, or backend infrastructure. The breach must be publicly acknowledged by Ubisoft or verified by credible cybersecurity sources (e.g., BleepingComputer, VX-Underground, official CVE disclosures, or established security research groups).

Resolution sources: Official Rainbow Six Siege X account announcements, Ubisoft's official security statements, or established cybersecurity news outlets.

The market resolves NO if no such breach occurs before January 31, 2026.

Background

Rainbow Six Siege suffered a breach that allowed hackers to abuse internal systems to ban and unban players, manipulate in-game moderation feeds, and grant massive amounts of in-game currency and cosmetic items to accounts worldwide on December 27, 2025. Ubisoft has confirmed the in-game abuse in Rainbow Six Siege, and there is no public evidence of a larger breach of player credentials. A second hack came after Ubisoft put Rainbow 6 Siege X back online after a December breach, with hackers displaying custom messages in the game lobby on January 4-5, 2026.

Considerations

Ubisoft faces dual security crises as outsourced helpdesk staff have been accepting bribes for panel access since 2021. Multiple unrelated threat groups may have targeted Ubisoft simultaneously—one exploited Rainbow Six Siege services directly while another allegedly exploited a MongoDB vulnerability to access internal Git repositories. The rapid succession of incidents within days suggests systemic vulnerabilities beyond isolated exploits.
