After Rainbow Six Siege was hacked and players were charged billions of in-game credits, Ubisoft urgently shut down the servers and rolled back the data.

PANews reported on December 29th that, according to Cointelegraph, French gaming giant Ubisoft was forced to suspend the online services of Rainbow Six Siege after a hacker exploited the vulnerability, distributing 2 billion R6 credits (in-game currency) to every player. On December 27th, the game team first confirmed the exploit through the X platform, subsequently releasing a series of updates and suspending game servers and the trading market the following day.

Reports from players on social media indicate that hackers gained control of key parts of the game's online system. Players claim that upon logging in, everyone received 2 billion R6 points, along with rare items such as skins and weapons. Screenshots shared by players also show that the hackers controlled the game's messaging and banning systems. The game sells 15,000 R6 points for $99.99 each, meaning players would need to spend approximately $13.33 million to accumulate 2 billion R6 points. On December 28th, the Rainbow Six Siege team announced on the X platform that they were working to revert R6 points earned after 11 AM UTC. The game is currently being tested with a small number of players in preparation for a relaunch.
