Marina Bay Sands Shopping Membership Programme Data Security Incident 

7 November 2023

Marina Bay Sands became aware of a data security incident on 20 October 2023 involving unauthorized third-party access on 19 and 20 October 2023 to some of our customers’ loyalty programme membership data.

Upon discovery of the incident, our teams immediately took action to resolve it. Investigations have since determined that an unknown third party accessed customer data of about 665,000 non-casino rewards programme members.

Based on our investigation, we do not have evidence to date that the unauthorized third party has misused the data to cause harm to customers.

We do not believe that membership data from our casino rewards programme, Sands Rewards Club, was affected.

After learning of the issue, we quickly launched an investigation, have been working with a leading external cybersecurity firm, and have taken action to further strengthen our systems and protect data.

The relevant personal data that was affected, where applicable, comprises:

• Name
• Email address
• Mobile phone number
• Phone number
• Country of residence
• Membership number and tier

We will be reaching out to Sands LifeStyle loyalty programme members and sincerely apologize for the inconvenience caused by this incident. We have reported it to the relevant authorities in Singapore and other countries where applicable and are working with them in their inquiries into the issue.
