dll-injection

I am making a 'mod' dll that modifies behaviour of the target process. I succeeded to inject my dll and hook some functions of target. But it requires more work to do when I need to hook some APIs BEFORE main module starts(more clearly, before the entry-point). I need to start the target program manually with CREATE_SUSPENDED attribute, inject, then resume. But some applications start with its own launcher program, some often start from x64 processes... such various environment make it hard to automate it. Seems like the best way's inject hooking dll to all process and handle CreateProcess.

I'm working on a C# application which uses the EasyHook library for DLL Injection. EasyHook requires that any application using it be strongly named. In order to strongly name the application I need to make sure that all the libraries I use are strongly named as well. This is easy to do for all of my managed libraries, but I also have an unmanaged c++ library which I need to strongly name. After some searching I can't seem to find a way to sign my unmanaged dll, even with the source code. Can this be done, and if so what do I need to do? Thanks for any suggestions or assistance! I assume that

I am facing a problem related to get out all the controls from some hooked process. My SpyDll launched into hooked process sucessfully, But when I check the statement Control control = Control.FromHandle(MainWindowHandle), it returns null into control object where "MainWindowhandle"is just a native main window handle of that hooked process, which you always take from .NET "Process" class after launching that process. But STRANGLY it happens that in some other hooked process which is the same C# .NET application, it returns valid object of Main "WinForm". So why it will not work in above case?

Following code will inject dll and DllMain will be called. How I call specific function from DLL, not just DllMain? DWORD pid; HANDLE hd; LPVOID gp, rs, proc; gp = (LPVOID)GetProcAddress(GetModuleHandle(L"Kernel32.dll"), "LoadLibraryA"); pid = 6096; hd = OpenProcess(PROCESS_ALL_ACCESS, 0, pid); rs = (LPVOID)VirtualAllocEx(hd, 0, sizeof(DLL_NAME), MEM_RESERVE | MEM_COMMIT, PAGE_READWRITE); if (!WriteProcessMemory(hd, (LPVOID)rs, DLL_NAME, strlen(DLL_NAME), 0)) { printf("WriteProcessMemory %d", GetLastError()); } if (!CreateRemoteThread(hd, 0, 0, (LPTHREAD_START_ROUTINE)gp, rs, 0, 0)) { printf(

Recently I have become interested in Linux, and am trying to create a program which is capable of injecting a shared object (i.e. .so file, 'dynamically loadable library', "DLL" under Windows.) I know this can be done by setting an environmental variable, but I want to do it on a process which is already running. I already know how to do this under Windows. There are several ways, but generally speaking you can just call LoadLibrary() by creating a remote thread using CreateRemoteThread(). Of course you need the address of LoadLibrary in the remote process, but (in my experience) it is always

I am working on DLL Injection but getting the error as failed to hook process: 87 The parameter is incorrect. The target process as well as the dll are both 64 bit. The Injection code is: BOOL HookInjection(TCHAR target[], TCHAR *dll_name) { // https://msdn.microsoft.com/en-us/library/windows/desktop/ms644990(v=vs.85).aspx // SetWindowsHookEx can be used to inject a DLL into another process.
