Personal information of some Club 21 members has been compromised, after hackers breached the luxury retail company's computer servers.
In an electronic mailer to its members yesterday, the company said that the May 19 attack on its computer servers resulted in "unauthorised access to data that included some customer information".
Club 21 said its ongoing investigations into the breach showed that hackers may have gained access to information such as members' names, gender, NRIC numbers, passport numbers and dates of birth, as well as addresses, telephone numbers and e-mail addresses.
"In a few limited cases, income range and past sales data were also affected. Much of this was partial in nature," said the circular, which was signed off by Club 21 Singapore general manager Yip Tien Tien.
Ms Yip said the company reported the incident to police.
"We also immediately triggered our incident response process. The break-in point was swiftly identified and closed; access to the data was removed," she said.
The circular added that while the matter was being investigated by the police, members were advised to be vigilant about their personal data, and employ good practices.
This includes never using components of personal data, like date of birth, for passwords.
