Name, phone numbers, email, employer, annual income, etc of over 70 lakh Indian debit/ credit cardholders are up on sale on the dark web, said security researcher Rajshekhar Rajaharia. The 2GB database has also information on whether users have activated mobile alerts. It also has PAN card details of 5 lakh cardholders. However, the card numbers are not available. The leak has probably happened from a third-party vendor of the bank who sells credit/debit.
