Target Data Breach, Target Corp. said a massive payment card data breach that occurred during the first three weeks of the holiday shopping season affected up to 70 million people, far more than previously estimated.
Target said an ongoing forensic investigation showed that certain customer information in addition to payment card data was stolen during the data breach.
The investigation showed that the stolen information included names, mailing addresses, phone numbers and email addresses.
“I know that it is frustrating for our guests to learn that this information was taken and we are truly sorry they are having to endure this,” Chief Executive Gregg Steinhafel said in a statement.
Target on Friday lowered its earnings expectations for the last three months of 2013, adjusting for the expected sales decline in the wake of the issue, which came weeks before Christmas.
Target said they will attempt to contact affected customers. The company has already offered one free year of free credit monitoring and ID theft protections to store customers.
