I'm not very savvy when it comes to the bank systems, and all I'm aware of are bank robberies. However, I never heard of this event, and this is indeed concerning. I doubt it would happen to towns with low crime rates, but knowing your money gets stolen is really depressing...
Upping the security would help for a little bit, but the security isn't optimal. This somewhat reminds me of another problem we are having: Identify theft. It relates a bit to this...and at least there are some steps being taken to end this hacking charade...
