30 lakh debit cards under threat to exposure to suspect ATMs

MUMBAI: Close to 30 lakh debit cards are understood to have been used in ATMs that are suspected to have exposed card and PIN details to malware at the back end.

While State Bank of India (SBI) has decided to reissue debit cards to six lakh customers who had used their cards at suspect networks, other banks are asking customers to change their ATM PIN. They are also blocking international transactions that can be conducted without PIN.

The problem relates to the feared breach in the systems of Hitachi Payment Services, which manages the ATM network processing for Yes Bank. The matter came to light around July. The private bank maintained that no compromise had been detected in its ATM network and that the measures were proactive.
