TD Ameritrade Corp.
The online brokerage company was hacked and had its contact information for more than 6.3 million customers stolen. TD Ameritrade, an Omaha-based company, admitted that the sensitive information in their database had been lost and mentioned that Social Security numbers and account numbers, were not taken.
In a strange twist of events, the company didn’t let anyone know just when the hack took place, because it was still looking into the theft at the time. Since then, there hasn’t been any clearly defined detail as to what happened with Ameritrade.
