Company officials notified guests whose information may have been compromised. They said that they were confident that “no financial, payment card or password data” was taken.
The properties owned by MGM Resorts that were part of the hack were not released. But the company has resorts in Las Vegas, Atlantic City, Detroit, Washington, DC, China and Japan, the BBC reported.
The company also runs the MGM National Harbor resort near Washington, D.C., the MGM Springfield casino and resort in Massachusetts, and the Gold Strike Casino Resort in Tunica, Mississippi, near Memphis.
