A major cyberattack has left MGM Resorts scrambling. The attack has impacted everything from the customer website to the gaming floor to the electronic room key system to corporate emails. What began on Monday has extended into Tuesday with the company’s website remaining offline.

MGM posted the following message on Twitter Monday afternoon acknowledging the issues:

“MGM Resorts recently identified a cybersecurity issue affecting some of the company’s systems. Promptly after detecting the issue, we quickly began an investigation with assistance from leading external cybersecurity experts. 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 message concluded.

Later, the company posted a follow-up:

“As an update to our previous statement, 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.”

For a while, even the slot machines were down for the count, as documented by the Twitter account Las Vegas Locally:

This is not the first major breach for the company either. In 2019, the company fell prey to hackers that obtained personal data of over 100 million users but did not report the incident until the following year.
