Citi says hackers accessed customer data

One of the nation’s top controllers of credit card debt recently revealed that hackers had gained access to the personal information of hundreds of thousands of people who have its branded cards.

Citigroup recently said that a hacking attack had exposed the personal data for about 1 percent of all its credit cardholders, according to a report from the New York Times. The company’s latest annual report showed it had about 21 million credit card members in North America at the end of 2010.

Included in the exposed information was customers’ names, bank account numbers, addresses and email information, the report said. The company also noted that data including Social Security numbers, dates of birth, credit card expiration dates and security codes was not compromised. The company is now in the process of notifying those whose information was accessed in the attack.

Credit card data breaches resulting from targeted hacking efforts have been in the news quite a bit lately, as Sony recently suffered an attack that exposed the payment information for millions of customers on its PlayStation Network.
