DBS Group (SGX:D05) said a ransomware attack on its vendor for the printing of customer statements and letters, Toppan Next Tech, "potentially compromised" customer statements/letters of about 8,200 DBS customers.

The Singaporean lender was informed by Toppan Next Tech on April 5 about the attack. However, DBS said its systems are not compromised and customers' deposits and monies are safe. Additionally, the lender has not observed any unauthorized DBS transactions resulting from the incident, according to a Monday release.

DBS said the majority of the affected data relates to accounts of its trading platform, DBS Vickers, while the rest pertains mainly to Cashline loan accounts.

Compromised customer data could include customers' first and last name, postal address, and details on equities held under DBS Vickers and Cashline loans, the release noted.
