The Verge is reporting that Target has recently become a target for hackers during the busy holiday season. Krebs on Security says the popular retailer is investigating a serious breach that could involve “millions” of customer credit and debit card records. Krebs says that the unfortunate breach “involves the theft of data stored on the magnetic stripe of cards used at the stores.” Online sales are said to be unaffected.
The Verge says that data that was stolen is “track data” which allows crooks to create counterfeit cards by encoding the information onto any card with a magnetic stripe. If the thieves also were able to intercept PIN data for debit transactions, they would theoretically be able to reproduce stolen debit cards and use them to withdraw cash from ATMs.
