SINGAPORE – A recent ransomware attack on Toppan Next Tech (TNT), a third-party printing vendor, has potentially compromised the personal information of over 11,000 customers from DBS Bank and the Bank of China (BoC) in Singapore. DBS disclosed that approximately 8,200 client statements might have been exposed, primarily affecting its trading platform, DBS Vickers, and cashline loan accounts. The compromised data includes customers’ names, addresses, and details of their equity and loan holdings.
Similarly, BoC reported that data from around 3,000 customers, used in printed correspondence managed by TNT, were potentially compromised. The exposed information may encompass names, addresses, and, in certain cases, loan account numbers. Both banks have assured customers that their core banking systems remain secure, and no login credentials or passwords were compromised. The affected communications were predominantly sent between December 2024 and February 2025.

Upon discovering the breach, DBS promptly notified the Monetary Authority of Singapore (MAS) and the Cyber Security Agency of Singapore (CSA). Both regulatory bodies are collaborating with the banks and TNT to investigate and manage the situation. DBS has reached out to the affected customers, advising them to remain vigilant and monitor their account activities closely. The bank has also offered complimentary credit monitoring services to the impacted individuals.
In response to the incident, BoC has implemented additional security measures to safeguard customer information and is working closely with TNT to assess the full extent of the breach. The bank has also contacted affected customers, providing guidance on monitoring their accounts for any unusual activities.
This incident underscores the critical importance of robust cybersecurity measures, not only within financial institutions but also among their third-party vendors. As cyber threats continue to evolve, banks and their partners must remain vigilant and proactive in protecting sensitive customer information. Customers are advised to stay alert for any suspicious activities related to their accounts and report any anomalies to their respective banks promptly.
