MGM Resorts International said it’s investigating a cyberattack that forced the gaming company to shut down certain systems, in a Monday post on X, the social media site formerly known as Twitter.
Multiple reports indicate guests are unable to use digital room keys, payment systems are not working and hotel restaurants can only accept cash.
The company said it has notified law enforcement and brought in outside cybersecurity experts to assist in the investigation.
MGM said the investigation is ongoing, and it is “working diligently to determine the nature and scope of the matter.”
MGM Resorts includes more than 30 hotel and gaming properties in the U.S. and abroad. A spokesperson for the city of Las Vegas referred questions to county officials.
MGM previously suffered a massive breach, as the personal data of about 10.6 million customers was posted on a hacking forum in 2020.
