On Friday, Target backtracked and said that debit-card PINs were among the financial information stolen from millions of customers who shopped at the retailer in late November and early December. However, it said the stolen personal identification numbers, which customers type into keypads to make secure transactions, were encrypted and that this strongly reduces risk to customers.
In addition to the encrypted PINs, customer names, credit and debit card numbers, card expiration dates and the embedded code on the magnetic strip on back of the cards were stolen.
Target has said it is still in the early stages of investigating the breach. It has been working with the Secret Service and the Department of Justice.
Target’s stock price rose 95 cents to $63.42 in afternoon trading Tuesday. It is nearly even with its price before the company disclosed the data breach.
