Sending Packets

[Interest07]

You mean you don't actually have one of those in your inventory?

[Smurfin]

not exactly lol, actually I used up all of the gsp I had before I got that message, was hoping it would do the opposite and keep giving me reps

[Interest07]

Hehehe, one can always try I suppose, but don't get your hopes up trying to cheat by sending packets, any decent game will check the actions server side

Botting will always be the easiest way to cheat

Am I blind or there`s no need for encryption? o.o

Interest07, just a quick question, not sendpacket related though but since u'r here i'll ask anyway

what can be used to detect connection state to the server so we can make an alarm to sound if a char is disconnected ?

sometimes having several clients running and logged in, after a few hours or days, only some of them might be disconnected while the others are fine.

By sending packets all clear, but somebody has found how to read the received packets?

Prolly have to see if the window informing you you have been disconnected is up. I've never looked around for it though, so don't have that info available.

This way you inject the packets just befor they are encrypted and sent to the server, so you don't need to encrypt them yourself indeed

[Smurfin]

can they put like 'reject unencrypted packet' routine in their patch ?

[Interest07]

Well, in order to send encrypted packets, they have to create the unencrypted packet first. Then send that packet to an encryption function. So you can always find the place where they do this, and inject your packet there. Until they start using a separate encryption function for every different packet, there won't be any problem.

They can't detect the fact you are injecting an unencrypted packet server side, because they are receiving an encrypted packet.

nice, then this sendpacket script will always work

Hello everyone, I am just switching from using C++ dll to inline C# code for injection code, but the client just crash all the time
Please take a look at the code and help me

public void testInjectNormalAtk(int pID)
        {
            string opcode = "";
            // asm
            // pushad;
            // mov eax, commonAtkAddress;
            // call eax;
            // popad;
            // ret;

            opcode += "60";
            opcode += "B8" + "5F51A0";
            opcode += "FFD0";
            opcode += "61";
            opcode += "C3";

            byte[] baOpcode = CalcBytes(opcode);

            IntPtr hProcess = openProcess(pID);

            IntPtr allocatedAddress = VirtualAllocEX(hProcess, IntPtr.Zero,  (IntPtr)baOpcode.Length );

            bool success = WriteMemory(hProcess, intPtr2UIntPtr(allocatedAddress), baOpcode, (uint)baOpcode.Length);

            IntPtr threadid = CreateRemoteThread(hProcess, allocatedAddress, IntPtr.Zero);

            WaitForSingleObject(hProcess);

            // clean up
            CloseHandle(threadid);
            VirtualAllocFree(hProcess, allocatedAddress, baOpcode.Length);
            CloseHandle(hProcess);
        }

Is there any thing wrong with the opcode ?

the last post was in wrong thread
thank all ^^

[Interest07]

I replied in the other thread you posted

[SunB]

I tracked the value in ESI when the call function call SendPackage but I dont know how to convert them like you guys did
Do I need to swap the high byte and low byte around? I think it's the way

[Smurfin]

Interest07, do yo have the log back in packet after using logout=1 or also the log in with id&pass packet after using logout=0 ?

[Interest07]

They aren't sent with this sendPacket function.

By the way I suppose nobody actually uses these cos I just noticed some mistakes hehehe.
