Several major hotels in Las Vegas, including the Bellagio, were left with faulty door locks, inoperable slot machines and other problems Monday after hotel officials said they were hit with a cyberattack.

The FBI said it is investigating the attack on MGM Resorts International hotels and has been in contact with the chain since Sunday. The hotel company said in a statement Monday morning that "it took prompt action to protect our system and data, including shutting down certain systems."

"Our investigation is ongoing, and we are working diligently to determine the nature and scope of the matter," MGM said in a post on X, formerly known as Twitter.

The company would not provide additional details of what was affected, however, it appeared to disrupt several key hotel systems.

On Monday night, MGM said its "casino gaming floors" were operational.

"We continue to work diligently to resolve this issue," the company said in a statement.

Bellagio guests were unable to charge anything to their rooms, make reservations, or use their digital room keys, according to ABC affiliate KTNV.

Several slot machines also appeared to be out of service at the Aria casino, KTNV reported.

The MGM international website was also down and was not allowing online bookings. The site redirected customers to their hotel's phone numbers for help.

Editor’s note: The cyberattack happened Sunday morning. An earlier version had an incorrect day, but has been updated in this latest version.
