MGM Resorts confirmed on Monday that it was hit by a cybersecurity issue, shutting down systems across its suite of casinos. The hotel giant owns a notable swath of casinos along the Las Vegas Strip, where some gamblers reported slot machines being taken offline because of the incident. At MGM Resorts' international properties, hotels are currently taking reservations via phone because of website shutdowns.
"MGM Resorts recently identified a cybersecurity issue affecting some of the company's systems," the company wrote in a statement. It said the company "took prompt action to protect our systems and data, including shutting down certain systems" in response to the attack. MGM Resorts has not confirmed how widespread the shut down is, what systems have been affected or other details about the incident.
Customer anecdotes report issues making reservations, using ATM machines, playing certain games and mobile key entry into hotel rooms, but Engadget has not independently confirmed these reports. While MGM Resorts informed the Las Vegas Metropolitan Police Department about the incident, the department said in a statement that these types of incidents are typically passed along to federal agencies.
Hotel and casino giant MGM Resorts has confirmed a “cybersecurity issue” is to blame for an ongoing outage affecting systems at the company's Las Vegas properties.
“MGM Resorts recently identified a cybersecurity issue affecting some of the company’s systems,” the company said in a statement posted to X, formerly Twitter, on Monday.
“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 statement reads.
According to reports on social media, the incident has led to outages impacting ATM cash dispensers and slot machines at MGM’s Las Vegas casinos, and forced hotel restaurants to accept cash-only payments. Guests also report that they cannot charge anything to their rooms and are unable to use their digital room keys.
A notice on the MGM Resorts website — also affected by the ongoing outage — confirms that the incident impacts all of its Las Vegas resorts, including Aria, the Bellagio, Luxor, MGM Grand and Mandalay Bay. Guests are advised to call to make a reservation or to speak to a concierge.
A source with knowledge of the incident told TechCrunch that all of MGM’s properties, including those outside of Las Vegas, appear to be affected by the incident. The websites of several of MGM's regional resorts, including MGM Springfield in Massachusetts, MGM National Harbor and the Empire City Casino in New York, were all offline at the time of writing.
