Looks like the coins are sent to a
coinpayments wallet, you can contact them and explain your case and they might block the account or if you are lucky enough and if you could provide evidence they might help you in recovering the coins. I have seen coins being recovered after the hackers sending to exchanges in the past, the faster you contact their customer support and state your case the better .
How do you know it's a Coinpayments wallet? I don't see it labelled anywhere.
At the very least, Coinpayments -- or any third party service -- will require a police report. That's hurdle #1 for the OP, and time is of the essence. Recovery is unlikely and Coinpayments isn't known for responsiveness.
Did all the inputs in that transaction belong to your wallet? Or is it possible he imported your private keys into another wallet?
