MGM Resorts is facing ‘Ongoing’ cyber incident that sent reservation and booking systems offline
KEY POINTS
- MGM Resorts said it had suffered a cybersecurity “issue” which the FBI characterized as “ongoing.”
- The casino operator’s gaming floors were back online as of Monday evening but the company did not provide a further update on its reservation and room booking systems, which had been taken down earlier.
- MGM shares fell about 2.4% by the close of trading Monday.
Casino and lodging operator MGM Resorts shut down a number of its computer systems including its website in response to a “cybersecurity issue,” the company said in a social media post Monday.
The initial shutdown impacted nearly every aspect of the casino operator’s business. Reservation systems, booking systems, hotel electronic key card systems, and the casino floors were all apparently impacted by the outage.
The company’s email systems were also apparently taken down in response to the cybersecurity issue, and have not yet come back online.
The company said that as of Monday evening, their casino floors were back online. But the reservation systems that power their thousands of hotel rooms and the booking system that controls reservations for their restaurants are apparently still down, more than a day after the first reports of the incident began to circulate.
“We quickly began an investigation with assistance from leading external cybersecurity experts,” MGM said in a post on X, formerly known as Twitter. “We also notified law enforcement and took prompt action to protect our systems and data, including shutting down certain systems.”
