Marina Bay Sands’ Security Breach Affects 665,000 Customers

Singapore’s Marina Bay Sands (MBS), a luxury resort and casino, disclosed in a public notice that personal data of 665K customers was exposed in a security incident.

According to the integrated luxury resort, the incident discovered on October 20, had an unauthorized third-party gain access to information belonging to members of the Sands LifeStyle loyalty program.

‘’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,’’ the statement read.

The leaked personal data included members’ name, email address, phone numbers, country of residence, membership numbers and tiers. However, based on its investigation, the company said that it did not find any evidence that the attackers had misused the data to harm the customers.

Nevertheless, this type of information can be used for various targeted scams, including phishing attacks.

Based on its investigation, MBS went on to say that casino members, who are part of the Sands Rewards Club, were not impacted by this incident.

In addition to an investigation, the company also engaged a third-party cybersecurity firm to gain further understanding of the attack and related damages. It has also deployed additional security measures to strengthen its system and protect data.

It further stated that Sands LifeStyle loyalty program members who had their data exposed in this breach, would be notified individually of this incident. The incident was also reported to the relevant authorities in Singapore and other countries where applicable.

This incident comes close on the heels of another major hacking incident of the famous MGM Resorts International and Caesars Entertainment in September 2023. The financially motivated attack is said to be carried out by the notorious ransomware group Scattered Spider (also known as UNC3944), believed to be a subgroup of ALPHV/ BlackCat gang.
