MGM Resorts Faces Major Cybersecurity Breach: A Deep Dive into the Incident


In a significant cybersecurity event that has sent shockwaves across the hospitality and gaming industry, MGM Resorts, a titan with a yearly revenue of $13 billion as of 2022, has confirmed it is grappling with a severe cybersecurity issue. This incident has led to the shutdown of systems at key Las Vegas venues, including the iconic MGM Grand, disrupting operations and online services across its portfolio of resorts such as Aria, Bellagio, Luxor, and Mandalay Bay.

The Incident Unfolds

The cybersecurity breach has had a tangible impact on the ground, with local reports indicating that even though some slot machines appear operational, they are unplayable. The ripple effect of the breach extends to the booking systems, official websites, and even basic guest services like check-ins and room key functionalities, which have been severely hampered. In response, MGM Resorts has had to revert to manual processes for guest check-ins, emphasizing that their casino gaming floors remain “operational.”

The Response

MGM Resorts has been swift in its response to the crisis, stating:

“Promptly after detecting the issue, we quickly began an investigation with assistance from leading external cybersecurity experts.”

The involvement of law enforcement and proactive measures to protect systems and data, including shutting down certain systems, highlights the gravity of the situation and the company’s commitment to resolving the issue.

Speculations and Insights

While MGM Resorts has not disclosed specific details about the nature of the cybersecurity issue, the characteristics of the incident bear resemblances to a ransomware attack. The decision to take systems offline, as noted by Ryan McConechy, CTO of Barrier Networks, is a standard yet costly move for organizations with extensive and complex networks. This action underscores the challenges organizations face in balancing operational continuity with the imperative need to contain and mitigate cyber threats.

Financial Implications

The financial toll of the cybersecurity breach on MGM Resorts is significant, with the company incurring massive losses for every minute the gaming floor was down, not to mention the ongoing impact due to the downtime of reservations and website services. The incident serves as a stark reminder of the economic vulnerabilities companies face in the digital age, where cybersecurity breaches can lead to immediate and substantial financial setbacks.

Historical Context

This is not the first time MGM Resorts has faced cybersecurity challenges. A notable data breach in 2019 saw a hacker access a cloud server, leading to the theft of guest information. 

Moreover, vulnerabilities in third-party “rewards” kiosks in Las Vegas casinos were exposed in 2019, highlighting potential risks in the casino’s operational technology.

The Way Forward

As MGM Resorts continues to navigate through the aftermath of this cybersecurity incident, the broader industry watches closely. The event underscores the critical need for robust cybersecurity measures, continuous vigilance, and the importance of swift, coordinated responses to cyber threats. 

For MGM Resorts and similar entities, this incident will likely serve as a catalyst for strengthening cybersecurity protocols and resilience against future threats.

In conclusion, the cybersecurity breach at MGM Resorts serves as a potent reminder of the omnipresent cyber risks in today’s interconnected world. As details continue to unfold, the incident reinforces the imperative for comprehensive cybersecurity strategies and the need for constant innovation in safeguarding digital assets and operational integrity in the hospitality and gaming industry.
