MIAMI (CBSMiami) – Days after a major data breach at Target stores, the company has released more information about the issue.
According to a statement from Target, PINs are safe.
The statement read: “While we previously shared that encrypted data was obtained, this morning through additional forensics work we were able to confirm that strongly encrypted PIN data was removed. We remain confident that PIN numbers are safe and secure. The PIN information was fully encrypted at the keypad, remained encrypted within our system, and remained encrypted when it was removed from our systems.”
Target also included more information about how PIN and the encryption process works.
“When a guest uses a debit card in our stores and enters a PIN, the PIN is encrypted at the keypad with what is known as Triple DES. Triple DES encryption is a highly secure encryption standard used broadly throughout the U.S. Target does not have access to nor does it store the encryption key within our system. The PIN information is encrypted within Target’s systems and can only be decrypted when it is received by our external, independent payment processor. What this means is that the “key” necessary to decrypt that data has never existed within Target’s system and could not have been taken during this incident.”
Target said that about 40 million credit and debit card accounts were possibly affected by the data breach that occurred just as the holiday shopping season shifted into high gear.
The chain said that accounts of customers who made purchases using their cards at its U.S. stores between Nov. 27 and Dec. 15 may have been exposed. The stolen data includes customer names, credit and debit card numbers, card expiration dates and the three-digit security codes located on the backs of cards.
The Minneapolis based company said it immediately told authorities and financial institutions once it became aware of the breach and that it is teaming with a third-party forensics firm to investigate the matter and prevent future breaches. It said it is putting all “appropriate resources” toward the issue.
Target Corp. advised customers to check their statements carefully. Those who suspect there has been unauthorized activity on their cards should report it to their credit card companies and call Target at 866-852-8680. Cases of identity theft can also be reported to law enforcement or the Federal Trade Commission.
