I received $1000 and was asked to send it back. How was this scam meant to work?
This is a very trivial scam. Flow is like this: Send money to Mr. X (you, in this case). Call Mr. X and ask for the money back, because mistake. Usually they ask for a wire transfer/cash/gift cards/prepaid cards or something else irreversible/untraceable. Mr. X initiates transfer back to Scammer. Accept the transfer from Mr. X Dispute the original transfer or otherwise cancel it through the netbank Mr. X cannot dispute his transfer to the Scammer, since it was genuinely and intentionally initiated by Mr. X. End up with twice the money, at the expense of Mr. X In other countries this is usually done with forged checks, but transfers can work just as well. As long as the transfer can be retroactively canceled or reversed - the scam works. You mentioned money laundering - this is definitely a possibility as well. They transfer dirty money to you from unidentified sources, and you send a "gift" to them with a clear paper trail. When the audit comes - the only proof is that you actually sent them the gift, and no-one will believe your story. You'll have to explain why the Mr. Z who's now in jail sent you a $1K of his drug money. However, in this case I think it is more likely a scam, and the scammer didn't really know what he was doing...
