In India millions of debit cards were “compromised”
A number of major Indian banks are taking safety measures amid fears that the security of more than 3.2 million debit cards has been compromised, BBC reported on Friday.
Some of the affected banks have been asking their customers to change security codes. They are also blocking and replacing debit cards.
The breach is thought to have been caused by malware on an ATM network.
Some customers are complaining that large sums of money have been taken from their accounts. Indian banks have issued nearly 700 million debit cards.
The National Payments Corporation of India (NPCI), which controls all retail payments systems in India, confirmed in a statement that there was a "possible compromise at one of the payment switch provider's systems".
"All affected banks have been alerted by card networks that a total card base of about 3.2 million could have been possibly compromised,"
the NCPI statement said.
It added that a total of 13m rupees ($194,612) have been withdrawn, mainly in China and the US, through fraudulent transactions so far, affecting 19 banks and 641 customers.
The NPCI has urged customers "not to panic"
because "corrective actions already have been taken"."The advisory issued by NPCI to banks for re-cardification [reissuing of new cards] is more a preventive exercise,"
Payment platforms like Visa, Mastercard and RuPay said their own networks were not affected but they were helping Indian authorities in their investigation. Several banks have also confirmed that they were taking measures to avoid fraudulent transactions.
