Target Gives More Details on Its Credit Card Hack
The company said that there is no indication that any debit card PIN numbers were compromised in a statement on Friday. It also said that, it doesn't appear that the three- or four-digit security code visible on the face of credits cards were breached. That means that the debit and credit cards that were compromised cannot be used to withdraw cash from an ATM or to shop online.
Target also said it believes customers' birth dates and social security numbers weren't compromised.
judging by the scope of the breach and the kind of information that criminals got, security experts say hackers targeted the retailer's point-of-sale system. That means they either slipped malware into the terminals where customers swipe their credit cards, or they collected customer data while it was on route from Target to its credit card processors.
