Citi Bank Reveals Attack... One Month Late

An anonymous reader writes "Is account security a thing of the past? Quote: 'We're talking a fairly serious hack, too. The personal and account information of some 200,000 Citibank card holders in North America was breached, reports Reuters, including contact specifics like names and email addresses. The solitary bit of good news? Citibank claims far more sensitive info like social security numbers, birth dates, card expiry dates and CVV card security codes was not compromised.'"

    Um, of COURSE CVV data wasn't compromised... What nimrod would store CVV in the same system as PAN? (That's Primary Account Number, for those of you who don't play with credit card data enough to stop using 'card number' as the term).

    In fact, just stating that CVV wasn't compromised bugs me. That should NEVER be exposed to anything that returns data. Heres how it should work:

    1. Merchant swipes your card into terminal (or keys it into whatever).
    2. Merchant reads and enters your CVV (or CVC or CVV2 or CID) into whatever.
    3. Authorization request is sent to the processor.
    4. Processor compares PAN and CVV to their records.
    5. Processor makes a decision.
    6. Processor responds to request.
    7. Merchant's system discards CVV if it didn't already.

    The CVV may not be saved by the merchant per PCI specs, and also per every processor spec that I'm aware of. If someone is able to get and match CVV etc with PAN, they do it by either intercepting authorization data or reching in and compromising processor and/or issuer databases that should not be connected to any external network. These should only be accessible by the 'inside' or secure side of trusted platforms, never externally.

    So you should hear of CVV-type data being disclosed only by terminals or POS software being compromised, or by someone carrying the data out of a building.

    And that Citi actually said this worries me just a little. Like hearing your 3rd grader's teacher telling you they always wear a condom to work. Um, why? that should NEVER be an issue, sirs.

    Of course, Citi might just be covering their bases, claming that no other data, even the stuff that should not even be connected, was taken. Again, doing it wrong, guys.

    ps - as an aside, there is a good chance that up to 30% of all cards in use have been compromised somehow, and no one bothers to replace them. Too expensive, they will run out of numbers faster than IPv4, and they handle the ongoing threat of fraud with existing fraud systems. No problem. Well, not much of a problem. I bet Citi doesn't even bother to replace these cards.

    Second aside, while waiting a month sounds bad, perhaps Citi was gathering history and understanding how these details would be used, to both crack the fraud rings and maybe connect them to the infiltrators. This will happen more and more as the banks especially decide to fight back and make an effort to find the perps of the intrusions. And about time.
