What I don't understand about these massive breaches is that once a pattern has been established all the cards get flagged... right? Which greatly increases the likelihood of subsequent transactions being flagged on the spot, which makes the risk of being caught much greater. Wouldn't the hackers and their clients be better served by much smaller batches of credit cards that aren't clearly from the same breach?

Those are just stingrays though, right? It's unclear as the article says towers but doesn't say whether anyone has actually seen a tower, only that they've detected attacks through their secure android phones.

If this is just a report of stingray use it should come as no surprise that they are in widespread use & that non-targeted phones latch on to the signals.

Can you expand on why it costs so much to upgrade a basestation? the fiber is already rolled out, the contracts between land owners have already been signed, the surveys for radio propagation have already been done. I honestly don't think the upgrade from 3g to LTE was nearly as expensive as the upgrade from EDGE/2g networks to 3g was for carriers. Also it was much, much quicker for them to roll out LTE networks vs 3g networks.
