Rainbow Six Siege temporarily shut down by Ubisoft after massive hacking incident

Ubisoft has temporarily shut down servers for Tom Clancy’s Rainbow Six Siege and its marketplace after players reported a massive hacking incident that resulted in strange behaviors, developer-only skins, and billions of credits being handed out. The incident comes at the worst possible time for Ubisoft, as Rainbow Six Siege has been enjoying continued success over the past month with its anniversary celebrations as well as daily reward giveaways.

Over the past few weeks, Siege has been gearing up for a big 2026, letting players mess around with new wildcard modifiers during Operation Tenfold Pursuit and giving them limited-time opportunities to earn daily rewards like the Roister and Great Consequence weapon skins and even a community artist bundle for operators like Smoke and Valkyrie. Ubisoft even surprised fans by releasing an Attack on Titan collaboration with Rainbow Six Siege that dresses Amaru up as Mikasa Ackerman and turns the hard-charging Oryx into an armored Titan. The bundle also comes with weapon skins, a universal charm, and more. Unfortunately, Rainbow Six Siege also saw an unwanted incident massively impact its game as well.

Rainbow Six Siege Temporary Taken Down by Ubisoft

On December 27, players had begun seeing some strange incidents while playing, including bizarre in-game messages as well as billions in R6 Credits being applied to accounts in Siege. Some players have even seen developer-only cosmetic skins becoming available to use out of the blue. After some players had begun to receive false bans, rumors quickly began circulating that Rainbow Six Siege had been breached by a hacker.

It wasn’t long before Ubisoft began posting updates from its official account and announced that Siege and the game’s Marketplace had been intentionally shut down while the development team worked on a fix. Five hours later, a new update from Ubisoft appeared and while the term “hack” wasn’t used, the studio provided fans with planned next steps, confirming that no bans would be issued to players who spent the credits they received and that the messages players had been seeing during matches were not triggered by the company as the ban ticker had been turned off in a previous update.

Ultimately, while Ubisoft continued to work on a permanent resolution to the incident, the studio would be rolling back all transactions to 11am UTC on December 27, a time deemed safe prior to the chaos that had ensued. Ubisoft also confirmed that its ShieldGuard system issued a banwave during the incident, but it wasn’t related to the events that were going on. Many players were surprised by how bad the situation got considering how often Ubisoft updates its anti-cheat systems for Rainbow Six Siege and its current push to remove cheating completely. Until the incident is fully resolved, players should likely avoid trying to access Rainbow Six Siege for now, waiting for official word from Ubisoft for when things are deemed all clear and good to go.

It’s been a long road for Siege, as the game experienced plenty of twists and turns, as well as ups and downs during development. While Rainbow Six Siege has reached its 10-year anniversary milestone, the developers recently opened up about the possible future of the franchise, hinting that the game could continue expanding and how “it’d be a shame” if the characters the team has developed and curated over the past 10 years were simply locked in Siege. Nothing has been announced or confirmed, but creative director Alexander Karpazis hinted that if there is a demand for it from fans, something like a single-player experience just might be possible down the road.
