Background The Personal Data Protection Commission (the “Commission”) was notified by Simmons (Southeast Asia) Private Limited ('SPL') on 17 August 2022 that it was subject to a ransomware attack on 10 August 2022. As a result of the attack, a test server containing the personal data of 87,824 customers was encrypted by ransomware. The personal data affected included the customers' name, address, email address, telephone number and customer information such as the sales order and date, product bought, amount paid, delivery date, time of delivery, date of payment, amount paid, mode of payment, and payment reference. The data of 128 employees, including their business email address, user ID, and password was also encrypted. The Commission noted that there was no evidence of exfiltration of the data. It was established that the threat actor(s) had likely gained access to the test server by exploiting an open Remote Desktop Protocol (“RDP”) port. The RDP port had been left open just 4 days earlier, on 6 August 2022, to facilitate access to the test server by a vendor for testing and development work. Remedial Actions After the incident, as part of a remediation plan, SPL put in place measures including: (a) Reformatted and restored the test server; (b) Closed the RDP port; (c) Ensured that any connection to any of SPL’s servers within its IT environment can only be made through a SSL/VPN or IPSec connection, and that all RDP ports on all its servers are closed to public internet access; (d) Issued a SSL/VPN account to its vendor for the vendor to connect to SPL’s network before accessing the test server; (e) Removed all production data containing personal data from test servers and will ensure that any future test servers will not contain personal data in any form; (f) Set up all future test servers on a separate domain so that the possibility of lateral movement is minim
