The Cyber Security Agency of Singapore (CSA) and the Monetary Authority of Singapore (MAS) are aware of a ransomware attack reported by Toppan Next Tech (TNT) to the Personal Data Protection Commission on the evening of 6 April 2025.

The attack has led to customer information from DBS Bank and Bank of China Limited, Singapore branch, being extracted by the threat actor. No customer log-in information has been compromised.

CSA is aiding TNT in their investigations and is advising them on containment measures. MAS is in close engagement with the affected banks on their risk mitigating measures and follow-up with customers. The impacted banks have placed the relevant accounts on enhanced monitoring, and are contacting affected customers as a matter of priority.

Ransomware threats are increasing in frequency and sophistication. CSA advises organisations to refer to CSA’s advisory for prevention and mitigation measures to deal with ransomware.
