According to a recent report from ZDNet, millions of previous guests of MGM Resorts hotels had their information posted online by hackers.

Among the guests on the list were Justin Bieber, Twitter CEO Jack Dorsey and officials with the Department of Homeland Security and Transportation Security Administration, according to ZDNet.
