Executive Summary

Marina Bay Sands, a luxury hotel and casino that is a landmark in Singapore, has recently experienced a major cyberattack. Since its opening in 2010, Marina Bay Sands has been renowned for its unique architecture and upscale amenities, located in the heart of the bustling city district of Singapore.

However, the resort is currently managing the fallout from a security breach that compromised the personal data of 665,000 customers.

This breach is part of a concerning pattern of cyberattacks targeting the hotel and casino sector. Other industry giants, such as MGM Resorts and Caesars Entertainment, have also been victims of similar breaches. The frequent occurrence of these incidents has highlighted the urgent necessity for the industry to bolster its cyber defences and develop swift, effective incident response plans.
