Target Hit by Credit-Card Breach
Target Corp. was hit by an extensive theft of its customers’ credit card data over the key Black Friday weekend, people familiar with the matter said, in what appears to be a brazen breach of a major retailer’s information security.
The theft happened in stores, not online, the people said. It may have been the result of software installed at the machines customers use to swipe their cards when paying for their purchases, one of the people said.
