Target representatives have confirmed that the PIN data was stolen through over 40 million accounts. Earlier the company has emailed users that their information is secure and very safe.
Target has released an official statement this morning:
"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."
