In Latest Attack, Hackers Steal Citibank Card Data - ABC News

About 200,000 Citibank credit card customers in North America have had their names, account numbers and email addresses stolen by hackers who broke into Citi's online account site.

Citigroup Inc. said it discovered that account information for about 1 percent of its credit card customers had been viewed by hackers. Citi has more than 21 million credit card customers in North America, according to its 2010 annual report. The New York-based bank, which discovered the problem during routine monitoring, didn't say exactly how many accounts were breached. Citi said it was contacting those customers.
Just 1%...kind of wondering how access was that limited...if perhaps these customers were part of an individual database?
