Late in 2013 national retailer Target's computer and point of sale systems were breached. In all about 70,000,000 (70 Million) customer records were stolen. The stolen data includes credit and debit card numbers, debit card pins, names, and addresses. This breach represents a huge risk for Target's customers' identity theft, and obviously the damage to affected customers' credit scores.
