If you don't have the coding knowledge to handle hackers on your own then chances are you shouldn't be running a pserver.
That being said there are a number of ways to handle hacks.
#1: Client side, check processes, check for injection, etc. If it happens send a report packet to the server and crash the client. If it's repeated then ban the client.
#2: Server side, calculate chance of a player landing a hit and if it becomes increasingly high over more than just a few hits then have it reported to a gm to check out/ban.
#3: Client side 2: run a mini scan of the conquer.exe in use and running processes and send a scan confirmation packet to the server before ever allowing them to log in (Ie: Server side check incoming connections for proper ip/confirmation packet before login) Should be combined with other methods though.
#4: Having proper staff/reporting.
