State of Connecticut v. Citibank, N.A.: Citibank has reached a $55,000 settlement with the state of Connecticut after hackers accessed the account information of more than 5,000 bank customers in-state and over 360,000 in North America.

The data breach occurred in May 2011, though the international banker did not report the theft of customers' account information until a month later. The hackers reportedly made $2.7 million worth of fraudulent charges using bank customers' accounts.
