Wired - Citigroup has been forced to reveal that a recent hack of its network exposed the financial data of more than 360,000 customers, a much higher number than the bank originally disclosed.
The company said last week that hackers who breached Citi Account Online on May 10 had acquired the personal information of about 1 percent of its 21 million North America customers, or approximately 210,000 credit card holders. But in a note posted to its website late Wednesday, the company revealed the new number, and said that it had known the number of customers affected was much higher as early as May 24.
The note didn’t indicate why the company hadn’t disclosed the higher number before, but The New York Times reports that the revelation comes after Connecticut’s attorney general and several other state regulators have opened investigations into the breach and begun demanding more information about it.
