The cyberattack, which was days later claimed by hackers from ALPHV subgroup Scattered Spider, caused widespread disruption across MGM’s properties, shutting down ATMs and slot machines and pulling the company’s website and online booking systems offline.
The hotel and casino giant first disclosed it had been targeted by a large-scale cyberattack on September 11. MGM Resorts has confirmed hackers stole an unspecified amount of customers’ personal information during a September cyberattack that will cost the hotel and casino giant an estimated $100 million.
