MGM Resorts International announced that it is negotiating with a cybersecurity issue that affected some of its systems, including its primary website, online reservations, and in-casino services, like ATMs, slot machines, and credit card machines.
The company disclosed on its X, formerly known as Twitter, “MGM Resorts recently identified a cybersecurity issue affecting some of the Company’s systems.”
It occurs that the outage began on Sunday night and computer systems in the resorts are currently down.
Reports online note that the firm swapped to manual operations, with the ATMs and credit card machines on properties having been impacted.
The MGM Resorts central website is also down, now reporting that consumers can make hotel reservations “at any of our destinations” over the phone.
MGM Rewards customers are also impacted, and they’ve been advised to contact a Member Services number between 6 AM and 11 PM, Pacific time.
All MGM websites operating the same domain name as the primary one – i.e. mgmresorts.com – have been out of service for hours.
Experts inspected several of them, and they all displayed the same note, guiding visitors to contact a phone number, including MGM National Harbor, Empire City Casino, MGM Springfield, MGM Grand Detroit, Beau Rivage, and The Borgata.
Some guests reported that their room keys were not functioning, according to FOX5.
Local Las Vegas media outlet Vital Vegas also informs that the slot machines are not operational, instead showing a temporarily unreachable message.
Reports have confirmed that the MGM Rewards app is no longer operating, urging users to visit the front desk for help. However, the cyberattack does not affect further MGM apps, such as MGM+ and the MGM Sportsbook.
The essence of the cybersecurity incident has not been revealed publicly, and the assaulter’s aim remains unspecified.
