I once worked for a small rural bank. It's scary how vulnerable the system is. Large banks like WF and BofA process their own data. However, most regional banks use a data processing company called FiServ. They process about 40% of all retail transactions, credit updates, etc. Hit FiServ with a denial of service attack at around 6am on consecutive days and/or penetrate their servers with viruses, and you could cause a MAJOR panic in retail banking.
