As far as I know - it would probably be a wire transfer - name may not matter. Depends on how they try to access the account. Did they ask for the routing number and checking account number of the bank, name of the bank, etc? Or just his account number?

What is interesting to note is that they called back - probably thinking they could get more info from your brother. I would report to the cops - they will put a bulletin on the news...that kind of stuff gets picked up pretty quick.
