In what could be the biggest breach of financial data in India, a malware injected in systems of Hitachi Payment Services, which provides ATM, and other services has lead to the compromise of 3.2 million debit card details. The banks affected include the State Bank of India, HDFC, ICICI, YES Bank and Axis Bank.
Of the debit cards affected, 2.6 million are on Visa and MasterCard platforms, while 600,000 are on the home-grown RuPay platform. The affected banks have asked card holders to change their pin numbers, and some have even reissued the cards. The malware infection reportedly took place weeks ago but came to the notice of the banks only a few days ago.
