"the request for cash was urgent"
The request may be urgent, but the account number should already be recorded if the accounting department is worth anything. That means that there should be no transfers to account numbers that aren't already recognized. CEOs need to impress their financial department that no transfers should ever be allowed, under any circumstances, to an unrecognized account no matter who calls.
I realize that a small company is less likely to have proper procedures in place, but a small company would probably not have over 200 grand to throw away. Here, we're talking about a company that does have that kind of money lying around. It is therefor a large company and should have proper procedures in place.
In any case, I'm guessing they are seriously thinking about implementing them now.
