DBS Bank and Bank of China, Singapore, have been accessed with user data following a ransomware assault on a printing merchant in Singapore.  ,
Toppan Next Tech ( TNT ) gave the Personal Data Protection Commission a report on Sunday evening ( Apr 6), according to the CSA and MAS on Monday.
” The hazard actor has retrieved customer data from DBS Bank and Bank of China Limited, Singapore unit,” the statement reads. No consumer log-in details have been compromised, according to the government.
DBS claimed that TNT had given the company information about the incident at around 10.20pm on Saturday.  ,
” Client statements/letters of about 8, 200 DBS users have been possible compromised, according to preliminary studies. These statements and letters mostly relate to DBS Vickers transactions.
The remaining consists primarily of Cashline product accounts. The bank stated that studies into the event are continuing.
DBS added that no damage to its devices had been done.  ,
Payments and funds held by users are secure. There is no proof of any unapproved DBS purchases that resulted from the affair to date.
The bank claimed that TNT’s tentative analysis  showed that the potentially affected statements and letters were primarily those that were sent to individual customers.
They were dated December 2024, January 2025 and February 2025.
DBS stated that it sends TNT user comments and letters for printing in encrypted files.
It’s unknown if the risk actor was able to decode the files because investigations are still being conducted.
First and last names, addresses, and information about equities held under DBS Vickers and Cashline loans are included in the statements/letters that could have been compromised, according to the statement. It also noted that the documents do not have login credentials, passwords, NRICs, loan balances, or full wealth holdings.
The affair did not occur within DBS’s techniques, but the lender claimed it takes it seriously and is contacting potential customers as a matter of concern.
By Tuesday, affected users who have registered their email addresses with the lender will be informed.
The user will be informed by actual message when DBS does not have the company’s contact address.
DBS instantly suspended all printing jobs with TNT and increased security to keep an eye on any suspicious or unusual bill action after being informed of the event.
TNT is getting assistance from CSA in their studies and is giving them advice on isolation actions.  ,
MAS is” close relationship” with the affected lenders regarding their customer follow-up and danger mitigating measures.  ,
According to CSA and MAS,” The effected banks have placed the appropriate accounts under increased checking and are contacting the affected customers as a matter of priority.”  ,
Organizations are advised to consult CSA’s expert for prevention and mitigation measures as ransom threats become more frequent and sophisticated.
