Ubisoft pulls Rainbow Six Siege offline as attackers cause chaos

Just a heads up, if you buy something through our links, we may get a small share of the sale. It’s one of the ways we keep the lights on here. Click here for more.

Over the weekend, Ubisoft appears to have briefly lost the keys to one of its biggest games, Tom Clancy’s Rainbow Six Siege, and things got weird fast.

Rainbow Six Siege, a highly competitive, team-based tactical shooter known for careful strategy and destructible environments, suddenly turned into something closer to a digital purge. 

Attackers reportedly infiltrated the game’s systems and took control of several core functions, effectively running the asylum while Ubisoft watched from the hallway.

By Saturday, the situation had escalated enough that Ubisoft intentionally took the game offline. 

With no single-player campaign to fall back on, Siege players were left staring at error messages and touching grass. As of Sunday, the servers were still down.

A rollback is currently ongoing and afterwards, extensive quality control tests will be executed to ensure the integrity of accounts and effectiveness of changes. The team is focused on getting players back into the game as quickly as possible. Please know that this matter is… https://t.co/cG4zBIBBGB

There’s been no official word on who’s responsible, but the X account VX-Underground ominously claimed the Siege incident may have coincided with broader intrusions at Ubisoft, possibly involving stolen proprietary code or even user data. 

None of that has been confirmed, but it’s enough to make any IT department sweat through their hoodie.

According to Bleeping Computer, much of what we know so far comes from player reports. And those reports paint a picture of absolute chaos. 

Attackers allegedly seized control of player bans and unbans, opened every cosmetic item to everyone, and dumped roughly two billion in-game credits into accounts, along with an equally economy-shattering amount of renown.

For extra flair, one player claimed the ban notification pop-ups were hijacked to slowly scroll out the lyrics to It Wasn’t Me, which feels almost rude given the circumstances.

It’s one thing for Rainbow 6 Siege to be completely taken over by hackers

Those credits are normally bought with real money, and Bleeping Computer estimates the giveaway amounted to about $13.33 million in value, though sadly, no one actually became rich. 

Ubisoft later said players wouldn’t be punished for spending the credits, but also confirmed that all purchases were being rolled back as part of repairs. So yes, it was fun while it lasted.

Ubisoft says engineers are working “with extreme care” to restore service, but timing remains uncertain. 

For now, Rainbow Six Siege remains grounded, another reminder that even the most tightly controlled tactical shooter can devolve into total anarchy with the right exploit.
