Anyone storing CCs in plain text deserve to get hacked.
Actually, anyone storing CC's these days EXCEPT the CC processors themselves pretty much deserve to get hacked because there is no good reason to do it, not even for recurring billing.
Anyone storing security codes needs to be dragged out in the city square and flogged, that's plainly against the rules and in many places an actual crime.
Someone was either being lazy or too cheap to upgrade to modern APIs, obviously violating every CC processing rule in the book, and got what they deserved IMO.
Hopefully these people never get permission to process another credit card again but the greedy companies will just slap 'em with a little fine, smile and look the other way after all the dust settles.
