百度的 libs.baidu.com 域名被恶意挟持插入广告

接着昨天的话题《求助:谁知道这些广告代码是哪里来的》,从昨晚开始,只要打开我的网站都会出现广告,并且网站的js效果都会失效:

2015-11-13_095731

今天早上使用浏览器调试工具,查看到有报错 jQuery 未定义,然后尝试切换了一下 jQuery 库的地址,广告竟然消失了,接着直接打开之前使用的百度的 jQuery 库地址 http://libs.baidu.com/jquery/1.8.3/jquery.min.js,发现根源了:

2015-11-13_095308

然后打开上面出现的js文件:http://120.25.147.157:3579/jq142/a/click.js,真的就是广告代码:

接着测试访问 http://libs.baidu.com/ 开头的所有网址,显示的代码都如上面第二个图片一样。问了下群里的朋友,都没这个问题,也就是说,这个问题只在我这边(广西玉林市博白县电信宽带网络)出现,是分地区的,不知是宽带商挟持的还是其他,然后  http://120.25.147.157:3579/jq142/a/click.js 的这个IP是阿里云的:

2015-11-13_102117

接着看广告代码的第二行,出现了域名 http://www.mangding.com 作为跟踪统计,不排除就是这个网站所有者或其服务器管理人员制造的这个广告代码,或者是由这个网站提供统计分析服务。

最后得出结论:

1.百度域名 libs.baidu.com 被恶意挟持插入广告,而且可能是分地区的,不排除宽带运营商操作的可能性

2.该广告代码托管于阿里云服务器,阿里云官方应该可以查看到这个用户,但是人家不会告诉我是谁

3.http://www.mangding.com 作为跟踪统计,不排除就是这个网站所有者或其服务器管理人员制造是这个广告代码,或者是由这个网站提供统计分析服务。

建议:

各大站长请先不要引用 百度域名 libs.baidu.com 下的文件,以免导致某些地区的用户受到广告骚扰。
