A day after Target announced that forty million of its shoppers had their credit and debit card data breached, the company provided details about the extent of the hack and what information could have been compromised.
Target, the nation's No. 2 general merchandise retailer, said cards used at the brick-and-mortar stores between Nov. 27 and Dec. 15 2013, may have been impacted.
The Department of Commerce and Consumer Affairs in Hawaii says that a number of Hawaii residents may have been affected by the breach.
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.
The retailer said it gave Visa, MasterCard, Discover and American Express the card numbers of those who may have been impacted, and that these companies will monitor those cards for fraud.
Target is also monitoring its own card, the REDcard, for potential unauthorized activity.
To help answer customer questions, Target set up a hotline for customers. Shoppers have been reporting long hold times, so Target said it will beef up its staffing. That hotline number is 1-866-852-8680.
Target didn't specify how its systems were hacked. But 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.
The retailer said it notified authorities and financial institutions immediately after it was made aware of the unauthorized access, and hired a forensics team to investigate how the breach may have happened. The issue that allowed the breach has been identified and resolved, according to Target spokeswoman Molly Snyder.
