Howdy folks!
Argh! That's all I can say at this point...
Further investigation is currently pointing to the credit card processing company being hacked. Since we do not keep credit card numbers on any server for more than a few days (the legal period in our jurisdiction is 30 days, but ours are rarely 'in play' for more than 2-3 days given the way we operate), it appears that only cards that actually had orders processed on them could be potentially impacted.
We've got nearly 30,000 customers in our databases, and all the folks reporting issues had orders 'processed' within the same timeframe. It appears that many card numbers that did not even exist on our servers at the time, but were processed (for DCU or other pre-orders) in the given timeframe, were compromised.
The processor has been notified, but they're not talking (yet.) I can't say as I blame them, as it could be them, or the bank itself or the Visa/MC system. We've re-routed our processing to our secondary processor until they can give us a full report on our inquiry. This not only gives us a little more comfort, but the loss of business will hopefully light a fire under their asses to provide an answer.
In the meantime, we've been running non-stop site testing all weekend to ensure that our cart itself is secure. All tests show that upon entering the actual cart pages, the URL is redirecting to the https SSL (Secured Socket Layers) pages, meaning that 256-bit encryption is still in play. At this encryption level, we can all remain confident that data submitted to us remains secure.
As I was very clearly inf0rmed when I reported the concern to the processor, I've told you as much as I am legally allowed to without threat of lawsuit and/or fines at this point. Apparently even if it comes back as proven to be a processor problem, there are strict limits as to what I am allowed to tell our customers. On one hand, that just seems crazy to me. At the same time, I would guess that a breech of this sort could have much further reaching economic implications were it not handled properly by the impacted retailer(s).
Hope that helps. Please feel free to share this inf0 with any other boards where the topic may arise. Keep a sharp eye on your credit card activity for the next few days. And, as always, please feel free to let us know if you have any questions at all.
Thanks,
