Introduction
MGM Resorts International, one of the world’s largest casino and hospitality companies, suffered a major cyberattack that disrupted operations across several of its hotels and casinos. The attack affected slot machines, hotel reservations, digital room keys, payment systems, and other critical services, causing significant inconvenience for guests and financial losses for the company.
Industry analysts estimated that MGM could be losing up to $8.4 million in revenue every day while the disruptions continued.
What Happened?
The cybersecurity incident forced MGM Resorts to shut down parts of its computer systems to protect customer data and contain the attack.
As a result, many services experienced disruptions, including:
- Slot machines going offline.
- Hotel reservation systems becoming unavailable.
- Digital room keys failing to work.
- Credit card and payment processing issues.
- Customer service delays.
Although hotels remained open, many operations had to be handled manually until systems were restored.
Estimated Financial Losses
According to analysts, MGM Resorts could lose between $4.2 million and $8.4 million in daily revenue, depending on how long the disruptions lasted.
The company was also expected to experience reduced cash flow as casino operations, hotel bookings, and customer services were interrupted.
These losses highlighted how costly cyberattacks can be for businesses that rely heavily on digital systems.
