a sophisticated security breach and clearly something that target is still getting its ahead around and i think federal envesters are getting their head around. i mean, at the end of the day, the thing to do if you re a target customer is call your bank and ask for a new credit or debit card. that s going to buy yourself peace of mind and security. if i was a target shopper, that would be the first thing that i would do. with the pin breaches, the security expert is exactly right. it s really hard to decrypt these kind i have pin codes because the key that decrypts them is held on the actual pin device, the hardware device in the store. so they would have to get access to countless numbers of pin devices and match them up with the credit card that they were swiped on in order to decrypt your code. i wouldn t worry too much about someone going to an atm and making a withdrawal with your stolen debit card but i would go and go ahead and call your bank
