[US] Received $1,400 via Apple Cash from a random number

Earlier today, I received an unexpected Apple Cash payment of $1,400 from an unknown number. The message just said “Yo” and included the payment — no name, no explanation. I replied asking who it was, but I haven’t gotten any response back.

The money does show up in my Apple Wallet, but idk. I’ve heard of scams where the sender does a chargeback or tries to trick you into sending the money back — could this be that?

Has anyone experienced this before or know what kind of scam this might be? I haven’t touched the money yet just in case. Any advice would help!
