Re: PIN numbers
Based soley on how the RAM scraping works, stealing the PIN codes is certainly possible if they were transmitted from the pin pad to an infected system.  I too read they were encrypted but I don't know if that was fact or damage control to prevent panic.

I don't know if we would know by now.   The criminals could be waiting for a future opportunity.  Right now this is highly publicized.  If I had millions of valid cards, I'd would think using them in an "Office Space" manner (Superman 2, Richard Pryor stealing fractional pennies) would be lucrative and potentially repeatable for a long duration.  Better to stay below the radar by adding a $5.13 charge from Starbuks (pun intended) to millions of accounts...

PIN numbers
I'm curious about PIN numbers for debit cards. Target said PIN numbers were taken in the breach, but that the numbers were encrypted. And that claim has not backfired as far as I know.

Do we know if encrypted PIN numbers can be accessed when BlackPOS malware is running on the POS device and/or the payment servers? I guess if stolen PIN numbers were being exploited we would know by now.

Exploiting Payment Servers vs. POS Controllers
"Exploited payment servers not POS systems, not store controllers running Windows..."

Isn't BlackPOS Windows malware?  At least I thought it was.  Perhaps I'm mistaken.  If it is Windows malware, what difference does it make that they didn't compromise POS systems or store controllers running Windows?  Either way they still compromised Windows.

I guess it's probably worse if they compromised payment servers since by design, they should be even more critically protected than an individual POS as they are a much higher value target.
