windows映像劫持技术（IFEO）介绍以及常用解决方案_问答一下，轻松解决，电脑应用解决方案专家！

前些日子在JM看到有关一个IFEO病毒的分析报告，就想写点什么和大家分享下！
为了使大家更详细了解映像胁持，在BAIDU找了一些相关知识点，在此，感谢那些原创作者！谢谢！

基本症状：可能有朋友遇到过这样的情况，一个正常的程序，无论把他放在哪个位置或者是重新用安装盘修复过的程序，都无法运行或者是比如运行A却成了执行B的程序了，而改名后却可以正常运行。。

既然我们是介绍IFEO技术相关，那我们就先介绍下：

一，什么是映像胁持（IFEO）？

所谓的IFEO就是Image File Execution Options

在是位于注册表的
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options

由于这个项主要是用来调试程序用的，对一般用户意义不大。默认是只有管理员和local system有权读写修改

先看看常规病毒等怎么修改注册表吧。。

那些病毒、蠕虫和，木马等仍然使用众所皆知并且过度使用的注册表键值，如下：
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\AppInit_DLLs
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServicesOnce
等等。。。。。。。。。。。。。。。

二，具体使用资料：

下面是蓝色寒冰的一段介绍：

@echo off   //关闭命令回显
echo 此批处理只作技巧介绍，请勿用于非法活动！//显示echo后的文字
pause   //停止
echo Windows Registry Editor Version 5.00>>ssm.reg
echo [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\syssafe.EXE] >>ssm.reg
echo "Debugger"="syssafe.EXE" >>ssm.reg   //把echo后的文字导出到SSM.reg中
regedit /s ssm.reg &del /q ssm.reg   //导入ssm.reg并删除

使SSM失效HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\svchost.exe项下的"Debugger"="abc.exe" 意思是不执行svchost.exe而执行abc.exe

可能说了上面那么多，大家还弄不懂是什么意思，没关系，我们大家一起来看网络上另一个朋友做得试验:

如上图了，开始-运行-regedit,展开到：

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options

然后选上Image File Execution Options，新建个项，然后，把这个项（默认在最后面）然后改成123.exe

选上123.exe这个项，然后默认右边是空白的，我们点右键，新建个“字串符”，然后改名为“Debugger"

这一步要做好，然后回车，就可以。。。再双击该键，修改数据数值（其实就是路径）。。
把它改为 C:\windows\system32\CMD.exe

（PS：C：是系统盘，如果你系统安装在D则改为D：如果是NT或2K的系统的话，把Windows改成Winnt,下面如有再T起，类推。。。）
好了，实验下。~ .

然后找个扩展名为EXE的，（我这里拿IcesWord.exe做实验），改名为123.exe。。。
然后运行之。。。嘿嘿。。出现了DOS操作框，不知情的看着一闪闪的光标，肯定觉得特鬼异~^_^。。

一次简单的恶作剧就成咧。。。

同理，病毒等也可以利用这样的方法，把杀软、安全工具等名字再进行重定向，指向病毒路径

SO..如果你把病毒清理掉后，重定向项没有清理的话，由于IFEO的作用，没被损坏的程序一样运行不了！

三，映像胁持的基本原理：　

NT系统在试图执行一个从命令行调用的可执行文件运行请求时，先会检查运行程序是不是可执行文件，如果是的话，再检查格式的，然后就会检查是否存在。。如果不存在的话，它会提示系统找不到文件或者是“指定的路径不正确等等。。

当然，把这些键删除后，程序就可以运行！

四，映像胁持的具体案例：

从这个案例，我们可以看到这个技术的强大之处！很多的杀软进程和一些辅助杀软或工具，全部被胁持，导致你遇到的所有杀软都无法运行！

试想如果更多病毒，利用于此，将是多么可怕的事情！
