According to the update， the gaming floors， featuring various slots， table games and poker rooms have resumed operations， and the guests will now be able to use slot dollars and freeplay. Furthermore， the slot ticket-in/ticket-out systems are now functioning smoothly. 

This announcement comes after MGM Resorts encountered a cybersecurity attack last week， impacting several of the company’s systems. The breach disrupted services， affecting the functionality of slot machines and necessitating a shutdown of the company’s internal computer systems. 

In an official statement， MGM Resorts acknowledged the situation， stating， “MGM Resorts recently identified a cybersecurity issue affecting some of the company’s systems. Promptly after detecting the issue， we initiated an investigation with the assistance of leading external cybersecurity experts. 

“We also notified law enforcement and took prompt action to protect our systems and data，Online Casino Games including shutting down certain systems. Our investigation is ongoing， and we are working diligently to determine the nature and scope of the matter.”

Upon detecting the issue， MGM Resorts immediately started an investigation in collaboration with external cybersecurity experts.

The cyber attack is believed to have been carried out by a group called ALPHV， using ransomware. The attack compelled the resort to shut down its computer systems， resulting in the disabling of hotel room pass cards， the booking system and gaming machines on the casino floor. 

This incident follows a similar cybersecurity breach at Caesars Entertainment， which also recently reported a breach. However， reports suggest that Caesars Entertainment chose to pay a ransom of approximately $15m， effectively preventing any disruptions in their operations.

Furthermore， in April 2023， Gateway Casinos in Ontario also experienced system outages due to a cybersecurity incident and was forced to close its locations.
