There is one person that continiously attacks my own ftp servers. I observed the IPs he left but doing whois on all of them i concluded that those are proxy servers (socks 5). I even found the site where he is getting them (sockslist.net). So my question is: Can I somehow trace back him through the proxy so i can get his own IP address and report it to the ISP ?
Is there any way to find someone's real ip if he is using proxy, i.e. trace through the proxy ?
Also a friend of mine told me that the attacker might be using VPN for protection - any way of tracing the connection through the VPN ?
Thank you in advance.
