windows映像劫持技术(IFEO)介绍以及常用解决方案

windows映像劫持技术(IFEO)介绍以及常用解决方案

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:

@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 >>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

http://bbs.2dai.com/attachments/month_0705/20070525_088ef84748fbbf4d225cRwCDcEAs5PMD.jpg

http://bbs.2dai.com/images/WLM/attachimg.gif



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!

-------------------------------------------------------
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!

五:如何解决并预防IFEO?

方法一:限制法(转自网络搜索)

它要修改Image File Execution Options,所先要有权限,才可读,于是。。一条思路就成了。。

开始-运行-regedt32 (这个是系统的32位注册表,和注册表操作方法差不多)

然后还是展开到: )

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

http://bbs.2dai.com/attachments/month_0705/20070525_4a6ece790b21124411e0pnkTtMjK1Yv9.jpg






方法二:

把项删除即可


方法三:

使用IFEO映像挟持修复程序修复!下载在附件!






方法四:

使用SREngLog 1.2 特别版——>修复指令文件——>映像胁持修复!










方法五:
使用autoruns这个软件 http://www.skycn.com/soft/17567.html   ——>选项——>选中“隐藏微软项目(Options-Hide Microsoft Entries)”,然后点工具栏上的“刷新”按钮,再把image hijack(映像胁持)的此时里的所有项目(这时微软项目被隐藏了,可以选择的一般就都是病毒创建的项目了)删除.

好像现在已经有这样的病毒了
