映象劫持使部分程序不可运行的解决方法

Image File Execution Options (IFEO in short)劫持

一、典型症状：双击某些可执行程序无法正常执行（或者说执行了没看到预期的结果）但改一个名字就可以。

二、典型案例：OSO.exe新变种60{.exe 美女游戏.pif （转载如下）

============================= 转载Start================================
OSO.exe 新变种
这是OSO.exe,美女游戏.pif,重要资料.exe的又一个新变种，以前截获的样本名为Worm.Pabug.ck ,这次由用户上报的病毒瑞星，金山均没有命名，但在病毒行为上大同小异。以下是具体分析：
此样本于2007年02月01日截获，跟上次的变种一样是采用记事本的图标，是一类IFEO映象劫持病毒 。（变种不同这处用红色加粗标识）

病毒行为分析：病毒运行后，会不断打开run time error的消息提示，直到系统资源耗尽，当然用任务管理器，结束error窗口可暂时减少提示的生成。

生成文件如下：（以系统盘为C盘，XP SP2为例）

三、解决方法：

可以手动删除添加的非法 IFEO 劫持项目，重启后即可。

四、提示：

防止Image File Execution Options        hijack(映象劫持)的方法是通过在SSM等行为防火墙中添加一条注册表的监控规则（如下图）来防御，具体可google ，或点此此处链接。

五、部分技术内幕：

Image File Execution Options (IFEO in short)

You can set up your application to start Visual Studio when you launch the application from Windows. Visual Studio will load your application, ready for debugging, but will not commence debugging until you issue an execution command. Having Visual Studio launch the debugger in this way is useful for debugging services and COM out-of-proc servers.

To setup an application to launch the debugger automatically

1. Start the Registry Editor (regedit).
2. In the Registry Editor, open the HKEY_LOCAL_MACHINE folder.
3. Navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\currentversion\image file execution options.
4. Under the Image File Execution Options folder, locate the name of the application you want to debug (myapp.exe, for example). If you cannot find the application you want to debug:
   1. Right-click the Image File Execution Options folder and choose New Key from the shortcut menu.
   2. Right-click the new key and choose Rename from the shortcut menu.
   3. Edit the key name to the name of your application, for example, myapp.exe.
5. Right-click the myapp.exe folder and choose New String Value from the shortcut menu.
6. Right-click the new string value and choose Rename from the shortcut menu.
7. Change the name to debugger.
8. Right-click the new string value and choose Modify from the shortcut menu.
   The Edit String dialog box appears.
9. In the Value data box, type devenv /debugexe.
10. Click OK.
11. From the Registry menu, choose Exit.
    The directory containing devenv.exe must be in your system path.
    Now, use any method to start your application. Visual Studio .NET will start and load the application.

    Note    If the application is managed, Visual Studio launches with the Debugger Type set to Auto. Before you debug, change the Debugger Type from Auto to Mixed in the Property Pages dialog box. For more information, see Specifying Debugger Settings .
