As a real estate underwriter at a regional bank, I order title work for loans that I am working on. Normally we close non-purchase loans in-house unless requested otherwise. Lots of the attorneys and title companies require that funds be wired. I have seen a couple of them lately where the wiring instructions were password protected and you had to call them for a password to even open them. The closers also contact the office doing the closing to match up the CD or HUD and wiring information gets verified before being sent. The loan administator or credit officer have to approve outgoing wires.
I could see where an individual sending payment for a transaction could be easily misled though.
