MGM's website was still down as of late Thursday in New York, while users have taken to social media to showcase some apparently inoperable gambling machines at the company's Las Vegas location. The company, in a message posted on X, said it was continuing 'to work diligently to resolve our cybersecurity issue while addressing individual guest needs promptly.' The data breach is still affecting MGM's computer systems, four days after the initial attack. It wasn't clear how the hackers were able to penetrate MGM's network. The hackers also asked for a ransom from MGM, Bloomberg reported, citing two people familiar with the matter. On Sunday, the hacker group started to infiltrate MGM Resorts, leading to a shutdown of some of the brand's casino and hotel computer systems, like its corporate email, restaurant reservation, hotel booking, and digital key card access, CNBC said.
