Re: DLL Injection

[valente500]

Well if I change the DLL_PROCESS_ATTACH case to this:
case DLL_PROCESS_ATTACH:
        MessageBoxA(null, "Injected!", "DLL", MB_OK);
        
        g_hInst = hInstance;
        dll_process_attach(hInstance, true);
        
        try
        {
                *cast(int*)0x12FE6C = 1337;
        }
        catch(Exception e)
        {
                MessageBoxA(null, "Exception!", "DLL", MB_OK);
        }
        
        MessageBoxA(null, "Finished!", "DLL", MB_OK);
break;


then I get the "Injected!" and "Finished!" MessageBox()s popping 
up, but not the "Exception!", so yes the code does get past the 
cast line (but still crashes). The same thing happens even if I 
remove the try/catch block and the cast line altogether.

I changed my post-mortem debugger from the default Dr. Watson to 
Visual Studio's just-in-time debugger, and after it displays 
"Finished!", I get an unhandled win32 exception in the injected 
process.

And yer, I would normally use WriteProcessMemory() for something 
this trivial, but I want to eventually do some more advanced 
stuff.
