Target breach could cost hundreds of millions, probe starts

The theft of credit and debit card data from 40 million Target Corp customers could end up costing hundreds of millions of dollars, but it is unclear who will bear the expense, lawyers and industry sources said. 

Target said on Thursday hackers had stolen the data of shoppers who visited its stores during the first three weeks of the holiday season. Americas's third-largest retailer said it was working with federal law enforcement and outside experts to prevent similar attacks in the future.
