MGM Resorts shuts down IT systems after cyberattack

MGM Resorts International disclosed today that it is dealing with a cybersecurity issue that impacted some of its systems, including its main website, online reservations, and in-casino services, like ATMs, slot machines, and credit card machines.

“MGM Resorts recently identified a cybersecurity issue affecting some of the Company’s systems,” the company announced on its profile page on X (formerly known as Twitter). The company says it started an investigation immediately after detecting the issue “and took prompt action to protect our systems and data, including shutting down certain systems.”

It appears that the outage started on Sunday night and computer systems in the resorts are currently down.

Reports online note that the company switched to manual operations, with the ATMs and credit card machines on properties having been affected.

The MGM Resorts main website is also down, currently informing that customers can make hotel reservations “at any of our destinations” over the phone.
