NEW YORK (CNNMoney) -- Citigroup acknowledged that a hack attack last month stole millions of dollars from customers' credit card accounts.

Citigroup (C, Fortune 500) told CNN that about $2.7 million was stolen from about 3,400 accounts on May 10.


The hackers actually accessed a much larger number of accounts: 360,083. Fewer than 1% of the hacked accounts had money removed from them, according to Citigroup.

The bank reiterated that customers will not be responsible from financial losses stemming from the attacks.

"Customers are not liable for any fraud on the accounts and are 100% protected," the bank said.
