1.00.18 - Anti DC Hack & Bad Packets

Hello guys i'm asking for some help (if someone wants to help me) :P:

So i'm using 1.00.18 GS and i have no source just files from internet and i want to fix the dc hack & bad packets gs crash.

I have the code for anti-dc hack, but dont know how to use it. I don't have sources, so i cant add it in protocolcore.

My question is if i make one .dll file and put it in there and hook it to the game server it will work or not

// DC Hack Fix
case 0x18:
if(aLen != 5 || aRecv[3] > 7)
{
Log.AddTime("[Anti-Hack][Crash Attempt] [DC Hack] (%s)(%s)",gObj[aIndex].AccountID,gObj[aIndex].Name);
Log.Hack("[Anti-Hack][Crash Attempt] [DC Hack] (%s)(%s)\n",gObj[aIndex].AccountID,gObj[aIndex].Name);
CloseClient(aIndex);
return;
}
break;

The code is from shatter open source (S2)
