I posed that question to my bank and was told (unconvincingly) that they do catch people, just it's kept quiet. I would think it would be the opposite - publicly tar and feather these people to deter more theft.
The Target hacker was Ukranian.
Who is going to go get him?
“but never do I hear anyone has been caught, much less prosecuted?”
NSA or govt is the culprit no doubt.
