I knew a guy who was scammed. And I've read articles of similar things. He got a fake cashier's check, deposited. Spent the money. Then when it turned out to be fake fit hit the shan. I don't recall his details.
However, they've started doing the same thing with Zelle. They convince the mark that they sent too much money by mistake. Then ask that the extra cash be sent to them by some other service. It's usually done to the elderly. Oddly, the guy I knew was my age. But it turns out the guy was into shady stuff.
