(Newser) – Hackers breached Citibank's systems early last month and may have made off with the personal data of hundreds of thousands of customers, the bank has revealed.

The bank says only credit card customers were affected, but the Times has spoken to several customers who say their debit cards were compromised. Analysts say it's very unusual for a financial institution to be attacked directly, as hackers tend to avoid their secure servers in favor of stealing account information indirectly.
