MGM Resorts International (NSX:MGM), the owner of hotels and casinos across the US, said it suffered a cyber-attack which caused a shutdown of all its digital systems including the ones used for guest reservations and bookings.
Falling victim to the attack late on Monday, nearly all of the group’s online activities were initially impacted, with gamblers at the group’s casino floors unable to play, while hotel electronic key cards and staff emails also stopped working.

Betting at the casinos has reportedly resumed with all systems back online, but customers using the group’s hotels and restaurants haven’t been as lucky, with booking and reservation systems yet to have come back online.
Unfortunately, the company’s website is also down and has been replaced with a list of phone numbers for ticketing, booking and hotel services, with hotel customers being told to get in direct contact with their site concierge to sort out any problems.
Hotel operations are one of the key driving forces in MGM’s performances every year and rake in more cash than its casino divisions, with the former bringing in US$706 million in revenues during the company’s last quarter compared to casino sales of US$492 million.
Whether this cyber incident has resulted in customer information being stolen by hackers remains unconfirmed, but the FBI said that the incident was “ongoing”.
Back in 2010, the personal details of over 10 million MGM customers were stolen via access to the group’s cloud server and uploaded online to a hacking forum - among the information released was people’s phone numbers, emails, dates of birth, and home addresses.
MGM Resorts dropped over 2% following the news and closed trading on Monday at US$42.70.
