The sensitive data of its Visa and RuPay debit card customers were compromised as some unknown persons hacked into the ATM Switch (servers) at the headquarters, said the Police.
“2,800 false transactions of Rs. 2.5 crore using 400 debit cards took place. It’s an international attack on the banking system. No customer account affected, dummy cards were used and switching system of the bank was hacked. Probe underway,” said Milind Kale, Chairman, Cosmos Bank.
According to the tentative estimates, the hackers have drawn Rs 78 crore by 12,000 Visa card transactions and transferred it out of the country, including bank accounts in Hong Kong.
