远程线程注入版获取SYSTEM权限 前段时间写<>，其间涉及远程 线程注入，想到本篇，返回来补充一点内容。sysproc_now.c并不具备良好的可移植 性，为了区分2000/XP/2003，被迫用GetVersionEx()做精确的OS版本判断。相较之下 远程线程注入更易移植些。 如果试图向winlogon.exe进行远程线程注入，编程时需要指定恰当的WindowStation， 否则可能无法与派生的子进程正常交互。 在MSDN中查看GetProcessWindowStation、GetUserObjectInformation等相关函数。 参看Inside 2K([7])第五章的"Interactive Services"小节。 使用终端服务测试CreateRemoteThread_1.c时，可能得到如下错误信息: "CreateRemoteThread() failed: 存储空间不足，无法处理此命令" 在主控台上测试则一切正常。开始以为是WindowStation的问题，转而动态获取其名 称，错误信息依旧。后来才想起MSDN中有如下信息: Terminal Services isolates each terminal session by design. Therefore, CreateRemoteThread fails if the target process is in a different session than the calling process. 暂不清楚是否有办法解决，如果没有办法解决，那sysproc_now.c还有存在的必要。 -------------------------------------------------------------------------- /* * Copyright (C) 2002, 2012 * The NSFOCUS INFORMATION TECHNOLOGY CO.,LTD. * ----------------------------------------------------------------------- * Author : NSFocus Security Team * : http://www.nsfocus.com * Maintain : scz * Version : 2.02 * Compile : For x86/EWindows XP SP1 & VC 7 * : cl CreateRemoteThread_1.c /nologo /Os /G6 /Gs65536 /W3 /D "WIN32" /D "NDEBUG" /D "_CONSOLE" /MT /link /RELEASE * : * Create : 2003-10-08 13:37 * Modify : 2003-10-08 17:02 * ----------------------------------------------------------------------- * The only thing they can';t take from us are our minds. !H */ /************************************************************************ * * * Head File * * * ************************************************************************/ #include #include #include #include /************************************************************************ * * * Macro * * * ************************************************************************/ #pragma comment( linker, "/INCREMENTAL:NO" ) #pragma comment( linker, "/subsystem:console" ) #pragma comment( lib, "kernel32.lib" ) #pragma comment( lib, "advapi32.lib" ) #define VERSION "2.02" #define MAXBUFLEN 8192 #define CHARBASE ';A';
