Ransomware Attack Compromises Data of Over 11,000 DBS, Bank of China Customers in Singapore

A ransomware attack on Toppan Next Tech, a printing vendor for DBS Bank and Bank of China in Singapore, has potentially compromised the personal information of over 11,000 customers. DBS Bank reported that around 8,200 customer statements were affected, mainly relating to its brokerage arm, DBS Vickers, and Cashline loan accounts. The compromised data includes names, postal addresses, and details of equities, but does not include login credentials or financial balances. Bank of China confirmed that approximately 3,000 of its customers were impacted, with compromised data limited to names, addresses, and some loan account numbers. Both banks have placed affected accounts under enhanced monitoring and are actively contacting the impacted customers. The Cyber Security Agency of Singapore and the Monetary Authority of Singapore are assisting in the investigation and advising on containment measures, with ongoing inquiries into whether the data was decrypted by the attackers.
