Attackers Caused So Much Chaos In Rainbow Six Siege, Ubisoft Shut Down The Entire Game
Over the weekend, Ubisoft apparently lost control of one of its biggest video games, Rainbow Six Siege, as attackers appeared to be breaking into it and taking over a number of key functions. The operators of the bizarro new game created a free-for-all mess that Ubisoft apparently couldn’t put to rest while keeping the game online.
So the game, a team-oriented tactical shooter like Counter-Strike but with an emphasis on destroying environments, was purposefully dropped on Saturday. As of this Sunday, it has not been supported. There is no campaign mode for the game, so there is nothing to play with the servers down.
There is no official statement about the identity of the alleged abusers.
The rollback is ongoing and after that, extensive quality control testing will be performed to ensure the integrity of the accounts and the effectiveness of the changes. The team is focused on getting players back into the game as quickly as possible. Please note that this matter… https://t.co/cG4zBIBBGB

Sadly, the X account of malware code and information repository VX-Underground claims that the Rainbow Six Siege attack coincided with several more extensive, and potentially even more dangerous, intrusions at Ubisoft, which are rumored to include the theft of proprietary code and possibly private user data, although none of this has been confirmed.
According to Bleeping Computer, there has been no public release of information about the status of the Rainbow Six Siege attack, and the reporting of that publication was taken from reports posted online by players.
How much damage was there? However, according to one X user, the attackers turned the ban announcement’s spoilers into a kind of meme sticker, making them remove the words “It wasn’t me” by Shaggy.

More importantly, Bleeping Computer claims that the attackers managed to ban players and ban mods, and distributed 2 billion credits in the game’s in-game currency, as well as an equally devastating amount of “renamed,” in-game playing points that also serve as currency. All skins and cosmetic items were unlocked for all players.
The credits are sold in real fiat currency, so, according to Bleeping Computer’s calculations, two billion credits translates to about $13.33 million—though it’s doubtful that someone has managed to turn that into real, real-world wealth.
Since their game is an asylum run by hostile inmates, Ubisoft took the Rainbow Six Siege servers, and the accompanying game market, offline while the developers prepared to put everything together. Ubisoft has posted on X that players will not be penalized for using credits that attackers have given them.
➡️ No one will be banned from using the received credits. A rollback of all transactions since 11 AM (UTC time) is in progress.
➡️ The ban ticker was disabled in the previous update. Any messages seen have not been processed by us.
➡️ The official R6 ShieldGuard ban wave has… https://t.co/zbPYDJQa3O

The bad news for players, is that as of Sunday, developers were in the process of rolling back all purchases as part of the fix.
The latest X post from Rainbow Six Siege as of this writing states that “The team is focused on getting players back into the game as soon as possible,” and that “the issue is being handled very carefully so, the timing cannot be guaranteed.”
Gizmodo reached out to Ubisoft for information on whether the attack actually extended beyond Rainbow Six Siege, whether data was stolen from Ubisoft, and whether there is any information yet on the nature of the attack and what vulnerabilities were exploited. We will update when we hear back.
