We've had our credit card hacked because our Credit union was hacked and several hundred cards were compromised. What made it funny was we had just been there to talk to the credit department on what we could do to protect ourselves and to put a security pass code on our accounts the week before. Our friend at the CU called us up to alert us that our card was one of the numbers hacked and asked if we had enjoyed the groceries bought in ITALY along with a great (expensive) dinner and show tickets. We asked why only some of the cards got hacked and according to our friend the first four numbers are the financial institution on credit/debit cards and that if the hackers get that number to show a real financial institution, they use a machine to run different combinations of numbers till they hit a working card number and only use some of the numbers the hackers bring up. Yes they(CU) issued new credit AND debit cards and took care of the charges. We don't use that card unless it's an emergency and we only do a purchase once a year to keep it active but pay it off immediately.She called as soon as the numbers were discovered before the letters went out, we had just paid it off and she knew we were NOT in Italy as the date of purchases was same day we had been in to see her and pay off the card.
