Background Hiap Seng Engineering Ltd (the “ Organisation ”) notified the Personal Data Protection Commission (the “ Commission ”) on 14 June 2024 of a data breach incident where its servers were infected by ransomware which encrypted files that contained personal data (the “ Incident ”).

Passwords were found stored in the VPN device’s configuration file and were encrypted using old encryption methods, which the threat actor was likely able to decrypt. The Incident affected the personal data of 10,000 individuals that included employees, ex-employees and contractor, most of which were stored and encrypted by the Organisation in an on-premise payroll software. Types of personal data affected included a combination of name, address, NRIC/FIN number, date of birth, photograph, work permit number, bank account details, telephone number and passport number. Upon discovery of the Incident, the Organisation took prompt remedial actions including an update of all account passwords and firewall rules, implementing geo-blocking to allow VPN connectivity from local IP addresses only, implementing two-factor authentication for all accounts on the network and procuring a new server with up-to-date security features.
