The Target data breach, which resulted in millions of shoppers having sensitive personal information stolen, was worse than initially thought. 

The company previously believed that hackers stole credit and debit card information from 40-million shoppers after Thanksgiving, but today it announced that an additional 70-million shoppers may have been affected. Target warns that information such as names, addresses, phone numbers and email addresses may have been stolen. 

Target says they will try to reach out to as many customers as possible to inform them of the breach. Those who may have used a credit or debit card at Target between November 27th and December 15th are advised to call their credit card company and request a new account number.
