How to get someone's real IP if they are using VPN

[FHRITP]

hello there, a couple of days ago i got hacked on steam. cant really tell if he is pro or not but he got my account information through a trojan horse wich i discovered after cleaning up my pc

i am gonna use a third-party software called "wireshark" to get his ip (set up a connection with him through steam from another user)
problem is, i suspect and believe he is using a VPN, is there any way to get to his real IP address?? plz post how to get past his vpn of any methods.

Counter-hacking is still hacking. You aren't going to get help here, at least not from me.
