The website of a casino operator owned by Jewish billionaire Sheldon Adelson was hacked by unidentified vandals who criticized his support for Israel.

The hackers on Tuesday took over the home page of websites run by the Las Vegas Sands Corp., the world’s largest casino operator, owned by Adelson. In addition to criticizing Adelson over comments he made in October about Iran and its nuclear program, the hackers also posted personal information about employees including e-mail addresses and social security numbers, according to The Morning Call newspaper based in Allentown, Pa.

The company e-mail system also reportedly was not working, and the Sands’ corporate website and the sites of its resorts in Las Vegas; Macau, China; and Singapore did not function.

The Las Vegas Sands websites were down on Wednesday, with messages saying they were undergoing maintenance.

During the hacking incident, the homepage of the website of the Sands Casino Resort in Bethlehem, Pa., showed a photo of Adelson standing next to Israeli Prime Minister Benjamin Netanyahu and dialogue saying “Damn A, don’t let your tongue cut your throat. Encouraging the use of weapons of mass destruction, under any condition, is a crime.” It was signed by the Anti-WMD team, according to The Morning Call.

The page also showed a map of the world with flames where Sands has casinos in the United States.
