My problem isn't so much the skimming as it is the length of time it took you guys to fix the problem :( 

It's not just the corporations getting breached, either-- hospitals are a very popular target, esp. for identity theft, and as someone mentioned, your credit card can get skimmed there, as well.  As was clearly the case here, most of these incidents are the doing of organized crime-- a lot of viruses too-- I've seen a lot of places give a figure of 40% of the viruses out there-- and generally they're the more virulent ones like the FBI and ILoveYou viruses, used to gather your personal information or ransomware.

(Whereas adware trojans and DNS tend to be the result of corporations and anti-establishmentarians, respectively.  Though counterintelligence groups are responsible for their share of DNS viruses as well...)
