Iranian hackers unleashed a withering cyberattack on the Las Vegas Sands Corp, the world's largest operator of casinos and a property of the avowedly pro-Israel billionaire and Benjamin Netanyahu-backer Sheldon Adelson, earlier this year, according to a report by Bloomberg News. The attack cost the company some $40 million in damages due to the technological meltdown that resulted in loss of key data, according to the report.
