The BSE on Tuesday sought clarification from State Bank of India, ICICI Bank, HDFC Bank, Axis Bank, and YES Bank regarding recent media reports on cyber attacks.

This comes in the wake of a serious case of card data compromise coming to light whereby 19 banks received complaints from 641 customers about fraudulent withdrawals totalling Rs 1.30 crore in September.

The exchange said reply is awaited from the banks.

In a statement, the National Payments Corporation of India (NPCI), the umbrella organisation for all retail payment systems in India, had last month said that initially a few banks complained that their customers’ cards were being used fraudulently, mainly in China and the US, while the customers were in India.

Apprehending that this could be a case of card data compromise, all ATM/PoS terminals in India and three card networks — RuPay, Visa and MasterCard — had worked in a collaborative manner in September, it said.
