Evan Schumann at The Hack Report reports today that some Cuban nationals were arrested in Florida with card dumps from the Polo and TJX breaches. The interesting thing to note is that the Secret Service says these guys in FL received the data from Eastern Europe. But from what we already know about TJX, the original hackers weren't from Europe, they were in and likely from Minnesota.
It'd be pretty cool to see a path analysis of these card numbers if one could be put together. How many times are the cards sold before they're actually used?
