Ron Reese, a Las Vegas Sands spokesman, said the sites were restored early Monday. The company first became aware of the hacking on February 12 when the company email went down.
Reese declined comment on whether the company’s U.S. internal systems were also operating again. The Nevada Gaming Control Board and FBI are investigating the hacking.
The hackers defaced the sites with images condemning CEO Sheldon Adelson for comments he made last fall at Yeshiva University in New York about using nuclear weapons on Iran. The hacking affected Sands’ corporate website, the sites for casinos in Pennsylvania and the Italian-themed Venetian and Palazzo on the Las Vegas Strip as well as casinos in China and Singapore.
