SetTarget

[dna001]

Hi
It's my first post on this forum, so first a big thanks for all the informations a found on it.


I'm having some trouble with the SetTarget function. Each time I called it I've got a wow critical error.

This is what I know. Tell me if I'm wrong =)

The SetTarget function located at 0x4C46F0 (3.2.2 Info Dump Thread) takes a WGUID as argument

I'm working in C# using the Fasm lib

Based on the Lbot source I found on this forum and Code Using SelectTarget - Game Deception - Forums

uint codecave = memory.AllocateMemory();

uint dwHiWord = (uint)(GUID >> 32);
uint dwLoWord = (uint)GUID; 

memory.Asm.Clear();
memory.Asm.AddLine("MOV EAX, [0x{0}]", dwHiWord.ToString("X"));
memory.Asm.AddLine("PUSH EAX");
memory.Asm.AddLine("MOV EAX, [0x{0}]", dwLoWord.ToString("X"));
memory.Asm.AddLine("PUSH EAX");
memory.Asm.AddLine("CALL 0x4C46F0");
memory.Asm.AddLine("ADD esp, 0x08");
memory.Asm.AddLine("RETN");

memory.Asm.InjectAndExecute(codecave);
memory.FreeMemory(codecave);

If someone can give me a little help, I will apreciate.

PS: Excuse me for my poor English

I think InjectAndExecute works with CreateRemoteThread, so you need to set thread base into FS segment register or something like that.

edit: also 0x004C46F0 is not target in 3.2.2a, its 0x004C4940

Well thanks for your answer Kryso ! My offset was wrong and my code too :\

memory.Asm.AddLine("MOV EAX, [0x{0}]", dwHiWord.ToString("X"));
memory.Asm.AddLine("PUSH EAX");
memory.Asm.AddLine("MOV EAX, [0x{0}]", dwLoWord.ToString("X"));
memory.Asm.AddLine("PUSH EAX");

Thanks for the help !
