Gaming regulators are now working to ensure Sands did everything possible to protect employee information. Email wasn't functioning and company employees remain unable to log into their work computers. The damage the hacking has done goes beyond the defaced websites, which Sands took down Tuesday morning. Sands spokesman Ron Reese declined to discuss whether credit card information was breached in the hacking, and instead pointed to a statement the company made Wednesday saying it was working through a step-by-step process to ascertain what systems had been impacted. Las Vegas-based casino operator Affinity Gaming announced in December that its credit-card transactions had been hacked and warned its 300,000 customers to take steps to protect themselves from identity theft.
