Target Hack Included PIN Numbers
by Tyler Durden
When the first response taken by major banks such as JPMorgan, in the aftermath of the massive 40 million credit and debit card hack of the third largest US retailer Target, was to lower ATM withdrawal and purchase limits, it became clear that there was more here than simply a well-organized credit card number scrape. And indeed, as Reuters reports, the hackers who compromised up to 40 million credit cards and debit cards also managed to steal encrypted personal identification numbers (PINs) according to a senior payments executive familiar with the situation. And since from there to emptying bank accounts and saved deposits is only a keystroke away, with no credit card processor intermediate to offload liability to, banks had no choice but to immediately limit debit card access to as much 10% of their clients, in JPM’s case, in an unprecedented first, which just may have shown the way of how to limit a cash withdrawal panic if and when the need to do so arises.
