MGM Resort Expects $100 Million Fallout from Recent Cyberattack

Executive Summary

MGM Resorts International, one of the world’s largest gambling firms, recently suffered a cyberattack resulting in a projected $100 million financial hit for the third quarter.

Although the breach exposed sensitive customer data predating March 2019, no evidence of identity theft or fraud has emerged. Also, the company determined that no customer bank or payment information was compromised.

MGM Resorts expects a minor dip in occupancy rates for October but anticipates a strong fourth quarter.

Despite the financial impact, MGM Resorts believes it has adequate insurance coverage, though the full extent of the breach’s consequences is yet to be determined.

Attack and Response

MGM Resorts promptly responded to the cyberattack by shutting down its systems to contain potential damage.

Customers shared images on social media following the attack, showing slot machines displaying error messages and long queues at hotels in Las Vegas. MGM has not commented on whether any ransom was demanded or paid.

While we experienced disruptions at some of our properties, operations at our affected properties have returned to normal, and the vast majority of our systems have been restored

said MGM Resorts President and CEO Bill Hornbuckle in an open letter to customers.

Hornbuckle apologized to customers and also expressed gratitude to employees who were stretched thin by the attack, as hotel services like reservations, casino gaming, digital keys and other services were disrupted.
