远程线程注入
2022/4/5 23:19:52
本文主要是介绍远程线程注入，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
在这里，我们使用两个方法，第一个是CreateRemoteThread方法，第二个是NtCreateThreadEx方法。通过查看源码可以发现CreaeteRemoteThread函数实现中调用了NtCreateThread函数的。
代码的最后，还给出用远程线程函数去启动一个ShellCode硬编码的线程函数 ，实现注入并弹出对话框。
一.使用CreateRemoteThread方法
一、启动远程线程去执行LoadLibrary（在目标进程家得到的函数的绝对地址/或者直接用当前进程的LoadLibrary的地址也可以）去执行在目标进程中已经写入的文件粒度对齐的DLL
#include "Ring3导入表Hook.h"
void _tmain(int argc, TCHAR *argv[], TCHAR *envp[])
{
//获得目标进程句柄
_tsetlocale(LC_ALL,_T("Chinese-simplified"));
TCHAR v1[MAX_PATH] = { 0 };
HANDLE ProcessHandle = NULL;
_stscanf(argv[0], _T("%p"), &ProcessHandle); //通过命令行接收父进程传递的目标进程的ProcessHandle
//提权
if (SunEnableSeDebugPrivilege(_T("SeDebugPrivilege"), TRUE) == FALSE)
{
return;
}
//获得动态库的完整路径
//获得当前.exe文件的位置
GetCurrentDirectory(MAX_PATH, v1);
//通过目标进程的完整路径进行数据的读取
#ifdef _WIN64
_tcscat_s(v1, _T("\\x64\\Dll.dll"));
#else
_tcscat_s(v1, _T("\\x86\\Dll.dll"));
#endif
//将该Dll注入到目标进程中（远程线程注入）
SunInjectionByRemoteThread(v1, ProcessHandle);
if (SunEnableSeDebugPrivilege(_T("SeDebugPrivilege"), FALSE) == FALSE)
{
return;
}
_tprintf(_T("Input AnyKey To Exit\r\n"));
_gettchar();
}
//提权
BOOL SunEnableSeDebugPrivilege(IN const TCHAR* PriviledgeName, BOOL IsEnable)
{
// 打开权限令牌
HANDLE ProcessHandle = GetCurrentProcess();
HANDLE TokenHandle = NULL;
TOKEN_PRIVILEGES TokenPrivileges = { 0 };
if (!OpenProcessToken(ProcessHandle, TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &TokenHandle))
{
return FALSE;
}
LUID v1;
if (!LookupPrivilegeValue(NULL, PriviledgeName, &v1))
{
CloseHandle(TokenHandle);
TokenHandle = NULL;
return FALSE;
}
TokenPrivileges.PrivilegeCount = 1;
TokenPrivileges.Privileges[0].Attributes = IsEnable == TRUE ? SE_PRIVILEGE_ENABLED : 0;
TokenPrivileges.Privileges[0].Luid = v1;
if (!AdjustTokenPrivileges(TokenHandle, FALSE, &TokenPrivileges,
sizeof(TOKEN_PRIVILEGES), NULL, NULL))
{
_tprintf(_T("LastError:%d\r\n"), GetLastError());
CloseHandle(TokenHandle);
TokenHandle = NULL;
return FALSE;
}
CloseHandle(TokenHandle);
TokenHandle = NULL;
return TRUE;
}
// 向目标进程写入DLL，并获得目标进程的Loadlibrary的函数地址，启动CreateRemoteThread去执行Loadlibrary加载DLL
BOOL SunInjectionByRemoteThread(TCHAR* DllFullPath, HANDLE ProcessHandle)
{
ULONG32 DllFullPathLength = 0;
PVOID VirtualAddress = NULL;
//在目标进程空间中申请内存
DllFullPathLength = (_tcslen(DllFullPath) + 1) * sizeof(TCHAR);
//目标进程空间中申请内存
VirtualAddress = VirtualAllocEx(ProcessHandle, NULL, DllFullPathLength, MEM_COMMIT | MEM_RESERVE, PAGE_READWRITE);
if (VirtualAddress == NULL)
{
int LastError = GetLastError();
_tprintf(_T("LastError:%d\r\n", LastError));
_tprintf(_T("VirtualAllocEx() Error\r\n"));
return FALSE;
}
//写入数据到目标进程空间
if (WriteProcessMemory(ProcessHandle, VirtualAddress, DllFullPath,
DllFullPathLength, NULL) == FALSE)
{
int LastError = GetLastError();
VirtualFreeEx(ProcessHandle, VirtualAddress, DllFullPathLength, MEM_RELEASE);
_tprintf(_T("WriteProcessMemory() Error\r\n"));
return FALSE;
}
PVOID LoadLibrary = NULL;
//得到导出函数Function（LoadLibrary）在目标进程下的绝对地址
#ifdef _UNICODE
LoadLibrary = (PVOID)SeGetProcAddressExW(ProcessHandle, L"Kernel32.dll", "LoadLibraryW"); //得到当前进程LoadLibraryW函数地址
#else
LoadLibrary = (PVOID)SeGetProcAddressExA(ProcessHandle, "Kernel32.dll", "LoadLibraryA");
#endif
// CreateRemoteThread --->让目标进程创建线程，去执行LoadLibrary(目标进程家的函数地址)加载目标进程中已经写入了文件粒度的DLL
// VirtualAddress是注入的DLL的地址
HANDLE ThreadHandle = CreateRemoteThread(ProcessHandle,
NULL, 0, (LPTHREAD_START_ROUTINE)LoadLibrary,
VirtualAddress, 0, NULL);
if (ThreadHandle == NULL)
{
_tprintf(_T("CreateRemoteThread() Error\r\n"));
VirtualFreeEx(ProcessHandle, VirtualAddress, DllFullPathLength, MEM_RELEASE);
return FALSE;
}
// 等待远程线程结束
WaitForSingleObject(ThreadHandle, INFINITE);
if (VirtualAddress!=NULL)
{
VirtualFreeEx(ProcessHandle, VirtualAddress, DllFullPathLength, MEM_RELEASE);
}
// 清理
if (ProcessHandle!=NULL)
{
CloseHandle(ProcessHandle);
}
return T RUE;
}
//得到导出函数Function（LoadLibrary）在目标进程下的绝对地址
ULONG_PTR SunGetProcAddressExA(HANDLE ProcessHandle, const char* ModuleName, const char* FunctionName)
{
WCHAR v1[MAX_PATH] = { 0 };
if (MultiByteToWideChar(CP_ACP, NULL, ModuleName, -1, v1, _countof(v1)))
{
return SeGetProcAddressExW(ProcessHandle, v1, FunctionName);
}
else
{
return 0;
}
}
//得到导出函数Function（LoadLibrary）在目标进程下的绝对地址
ULONG_PTR SunGetProcAddressExW(HANDLE ProcessHandle, const wchar_t* ModuleName, const char* FunctionName)
{
if (!ProcessHandle) //no process specified
{
ProcessHandle = GetCurrentProcess();
}
//枚举目标进程的模块信息（ProcessHandle传的是目标进程的句柄）
DWORD ReturnLength = 0;
if (EnumProcessModules(ProcessHandle, 0, 0, &ReturnLength)) //预读，返回长度
{
HMODULE* ModulesHandle = (HMODULE*)malloc(ReturnLength * sizeof(HMODULE)); //申请内存
if (EnumProcessModules(ProcessHandle, ModulesHandle, ReturnLength, &ReturnLength)) //枚举模块信息，基地址返回到ModulesHandle
{
for (unsigned int i = 0; i < ReturnLength / sizeof(HMODULE); i++)
{
wchar_t ModuleFullPath[MAX_PATH] = L"";
//获得模块完整路径
if (GetModuleFileNameExW(ProcessHandle, ModulesHandle[i], ModuleFullPath, _countof(ModuleFullPath)))
{
wchar_t* v1 = wcsrchr(ModuleFullPath, L'\\'); //阶段完整路径，得到模块名字
if (v1)
{
v1++;
//此时我们ModuleName传参是Kernel32.dll
if (!_wcsicmp(v1, ModuleName)) //找到了我们要的模块
{
//获得当前进程下模块基地址
HMODULE ModuleBase =
LoadLibraryExW(ModuleFullPath, 0, DONT_RESOLVE_DLL_REFERENCES | LOAD_LIBRARY_AS_DATAFILE);
if (ModuleBase)
{
//获得目标函数（LoadLibrary）在当前进程下的地址
ULONG_PTR FunctionAddress = (ULONG_PTR)GetProcAddress(ModuleBase, FunctionName);
if (FunctionAddress)
{
FunctionAddress -= (ULONG_PTR)ModuleBase; //rva 计算Function的相对地址
FreeLibrary(ModuleBase);
return FunctionAddress + (ULONG_PTR)ModulesHandle[i];
//va 返回Function（LoadLibrary）在目标进程下的绝对地址
}
}
break;
}
}
}
}
}
free(ModulesHandle);
}
return 0;
}
二、使用NtCreateThreadEx方法
区别在于NtCreateThreadEx是未导出的Nt系列的函数，其实并没有技术的升级，而是进行了创建远程线程函数的升级，通过查看源码可以发现CreaeteRemoteThread函数实现中调用了NtCreateThread函数的。
void Nt创建线程扩展()
{
TCHAR ImageName[MAX_PATH] = { 0 };
HANDLE ProcessHandle = NULL;
HANDLE ThreadHandle = NULL;
LPVOID VirtualAddress = NULL;
HANDLE ProcessIdentify = INVALID_HANDLE_VALUE;
NTSTATUS Status = STATUS_UNSUCCESSFUL;
LPFN_NTCREATETHREADEX NtCreateThreadEx = NULL;
// 输入目标进程名称
SunInputImageName(ImageName);
{
GetCurrentDirectory(MAX_PATH, __DllFullPath);
_tcscat_s(__DllFullPath, _T("\\Dll.dll"));
}
//__DllFullPath = 0x00007ff641b8a560 L"Z:\\X-Project\\X-Project\\Dll.dll"
// 枚举进程，找到目标进程的ID
if (SunGetProcessIdentifyByImageName(ImageName, &ProcessIdentify) == FALSE)
{
goto Exit;
}
// 当前exe模块中没有该函数导入
NtCreateThreadEx = (LPFN_NTCREATETHREADEX)GetProcAddress(GetModuleHandle(_T("NTDLL.DLL")),
"NtCreateThreadEx");
if (NtCreateThreadEx == NULL)
{
goto Exit;
}
// 通过进程ID获取进程句柄
ProcessHandle = SunOpenProcess(PROCESS_ALL_ACCESS, FALSE, ProcessIdentify);
if (ProcessHandle == NULL)
{
goto Exit;
}
SIZE_T DllFullPathLength = 0;
// 在目标进程空间中申请内存
DllFullPathLength = (_tcslen(__DllFullPath) + 1) * sizeof(TCHAR);
// 目标进程空间中申请内存
VirtualAddress = VirtualAllocEx(ProcessHandle, NULL, DllFullPathLength, MEM_COMMIT, PAGE_READWRITE);
if (VirtualAddress != NULL)
{
// 将DLL写入到目标进程中
if (!SunProcessMemoryWriteSafe(ProcessHandle, VirtualAddress, __DllFullPath, DllFullPathLength, NULL))
{
goto Exit;
}
// 在目标进程中启动线程
Status = NtCreateThreadEx(&ThreadHandle,
THREAD_ALL_ACCESS, NULL, ProcessHandle, (LPTHREAD_START_ROUTINE)LoadLibrary, VirtualAddress,
FALSE, NULL, NULL, NULL, NULL);
if (!NT_SUCCESS(Status))
{
goto Exit;
}
}
WaitForSingleObject(ThreadHandle, INFINITE);
Exit:
if (VirtualAddress != NULL)
{
VirtualFreeEx(ProcessHandle, VirtualAddress, sizeof(__ShellCode), MEM_RELEASE);
VirtualAddress = NULL;
}
if (ThreadHandle != NULL)
{
SunCloseHandle(ThreadHandle);
ThreadHandle = NULL;
}
if (ProcessHandle != NULL)
{
SunCloseHandle(ProcessHandle);
ProcessHandle = NULL;
}
}
三、
我们还可以用远程线程函数做一些其他的事情
如去启动一个ShellCode硬编码的线程函数
这里我们使用ShellCode去注入，弹出一个对话框。
#include "stdafx.h"
#include <Windows.h>
