Since Ubisoft’s recent Rainbow Six Siege currency hack, the company has shut down false claims of an additional data breach.
This weekend, players of Tom Clancy’s Rainbow Six Siege were left confused after a major in-game exploit disrupted normal play. Following the incident, Ubisoft temporarily shut down the game’s servers and marketplace across all platforms. Players reported receiving developer-only cosmetic items, billions of in-game credits and, in some cases, account bans. Ubisoft also responded to claims that the incident involved a broader data breach. Those allegations have since been debunked, with the company confirming that no user data was compromised.
On the morning of Saturday, December 27, 2025, a slew of Rainbow Six Siege players reported seeing huge amounts of in-game currency, Renown, Alpha Packs, and even exclusive cosmetic items they never unlocked. At the same time, numerous accounts were hit with random bans. Some players explained these bans were later reversed, adding to confusion around what was actually happening on Ubisoft’s backend systems. Sources revealed that a hacker gifted players a combined $339,960,000,000,000 worth of in-game currency.
One report stated that “numerous accounts, including those belonging to Ubisoft, streamers and possibly official profiles, received random or erroneous bans, some of which were later reversed.” The report added that the incident appeared to be the result of an active exploit, warning players to avoid logging in until Ubisoft confirmed it was safe to do so. According to a post on the official Tom Clancy’s Rainbow Six Siege X account, the backend team investigated the issue for approximately an hour before making the decision to shut down the game’s servers and marketplace.
As of Sunday night, Ubisoft said it had completed testing and restored access to Tom Clancy’s Rainbow Six Siege, allowing players to return to the servers. In a post on X, the company outlined next steps as it continues to address the issue and assess compensation.
“The rollback is complete,” the post said. “Players who did not log in between Dec. 27 at 10:49 UTC and Dec. 29 should see no changes to their inventory. For those who did connect after Dec. 27 at 10:49 UTC, a small percentage of players may temporarily lose access to some owned items. Investigations and corrections will continue over the next two weeks.” Ubisoft added that the in-game marketplace remains closed pending further investigation.
Separately, claims circulated online suggesting a second, unrelated incident had occurred at the same time. Those allegations alleged Ubisoft had suffered a large-scale data breach involving roughly 900 gigabytes of data, including source code, internal tools and development materials from past and upcoming projects. However, the group behind those claims did not provide any evidence to support them, and the allegations have since been widely dismissed. While multiple data breach claims surfaced across social media, much of the discussion appears to have stemmed from individuals attempting to capitalize on the attention surrounding the in-game exploit rather than from verified information.
Sources from Ubisoft told Insider Gaming that “the company’s security team have been made aware of some breaches earlier this year following leaks surrounding projects such as ‘Scout’ and the since-cancelled Far Cry game codenamed ‘Talisker’.” Otherwise, only one hack incident has been reported, and the Rainbow Six Siege teams are currently working to mitigate it.
