Microsoft is facing a massive hack of its Minecraft account, which would mean millions of accounts were stolen in one fell swoop.
The company is now investigating whether the hack was an act of cybercrime, and said that it’s taking “all necessary steps to prevent further damage” to its Minecraft accounts.
Minecraft is a free-to-play Minecraft game, but has earned millions of downloads and is available for free on Xbox Live, PlayStation Network, PC, and mobile platforms.
The breach has affected at least one million accounts, but Microsoft said it does not know the identity of the hacker.
Microsoft is working to confirm whether the account was stolen or hacked.
The account is now listed as “unsecured,” and users should be able to log in and play games normally.
Microsoft said that the account hack has not affected any other accounts, and that it will notify users about any issues.
Microsoft’s chief security officer, David A. Coates, said in a blog post that “the damage is real, and we are taking all necessary steps.”
Coates noted that “accounts in breach are locked to prevent unauthorized access to them,” and that Microsoft will notify players who lose their accounts if they attempt to log into Minecraft accounts from another network.
He added that the company will be providing instructions on how to restore an account, if it is lost.
Microsoft has not provided any evidence of the theft.
Minecraft accounts have also been compromised in the past.
In 2012, a hacker gained access to Minecraft accounts for $1 million.
In March 2014, a group of hackers stole a total of over $300 million in virtual currencies from a company called BitPay.
