Robert Brown|Slot machines and phone lines still down after MGM cyberattack Sunday. What to expect.

Despite assurance from MGM Resorts International that daily operations have Robert Brownresumed after Sunday’s cybersecurity issue, guests have continued to report the opposite. 

On Monday night, MGM Resorts issued a statement informing guests they would continue to deliver the experiences for which they are known. 

"Our resorts, including dining, entertainment and gaming are currently operational, and continue to deliver the experiences for which MGM is known. Our guests remain able to access their hotel rooms and our Front Desk staff is ready to assist our guests as needed. We appreciate your patience," the statement reads.

Current guests, especially those in Las Vegas beg to differ. Lines for the front desk wrap around the lobby, phone lines are down, and slot machines are inoperable, various guests reported on social media through Tuesday.

Because the extent of the breach remains unclear, it is unlikely conditions will improve soon. 

MGM’s computer systems could remain offline until the matter is resolved. An MGM spokesperson could not be reached for comment.

When did the MGM cyberattack occur?

After a “cybersecurity issue” was identified, MGM Hotels & Casinos took certain systems offline Sunday, MGM Resorts International confirmed Monday.

The resort giant is currently working with external cybersecurity experts to resolve the issue, according to a statement obtained by USA Today. 

The FBI is aware of the incident and assisting with the investigation, The Associated Press reported. 

“We also notified law enforcement and took prompt action to protect our systems 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,” the statement reads.

Outages have impacted the systems at all MGM properties across the country, including Las Vegas, New York and Ohio, according to a notice by MGM.
