    关于”马爷”网络钓鱼的分析报告

    别人经典渗透过程学习 admin 2162浏览 0评论

    2014-01-20 知道创宇 网站安全中心

    一、背景

    网络钓鱼：攻击者向网民发出欺骗性的信息，意图引诱网民给出敏感信息（如：QQ账号密码、银行卡信息、在线支付平台账号密码等）。

     

    网络诈骗、网络钓鱼、伪基站、黑帽SEO、黑色产业链近几年仍然猖獗，本文主要针对某网络钓鱼案例给大家揭露黑色产业链背后的事情。

     

    2013年9月份左右腾讯管家监测到一批被挂非法跳转钓鱼页面的网站，很多网站被黑客非法入侵后，均被上传恶意文件至受害网站根目录下，其中文件名大略有：_sys.asp、bas.asp、pro.asp、dawm.asp这四种命名方式。

     

    例如被挂恶意文件的网站链接：http://gnxwhg.com/pro.asp?&jcjlz9pzd0y&te

    访问后页面将会跳转至钓鱼网站：

    1. http://zohqdt.eicp.net:2/27/
    2. http://qkepisav.vicp.cc:2/27/

     

    当我们第二天访问被黑网站链接的时候，跳转页面变成其他钓鱼页面了，有趣。

     

    二、网站被黑分析统计

     

    首先我们进行被黑网站IP段分析统计：

    IP图表分析统计：

    其中有4台主机IP相邻，112.121.176.67-70其中包含10个被黑网站。

     

    于是我们开始对被黑服务器进行容器分析，得出结果图表统计如下：

    • Microsoft IIS/6.0         27
    • Microsoft IIS其他版本    13
    • 其他                    9

     

    根据图表我们可以清楚的看到使用IIS容器的服务器占82%的比例，仅IIS/6.0就占有55%的使用率。

     

    后面我们又分析了被黑网站的应用指纹信息（应用系统）：

     

    其中WordPress, 帝国CMS, Dedecms, 精良南方居多比例，其他应用也是鱼龙混杂各式各样。

     

    我们为什么要进行以上的分析统计呢？： 排除攻击者使用0day攻击的可能性

    所以根据我们推测，钓鱼团伙极有可能用廉价去大量收购Webshell（网站控制权限），从而节省自己入侵网站上传恶意跳转页面的时间。

     

    根据以上几点分析，简单的想象一下大致流程：

    1. 廉价大量购买Webshell
    2. 人工或自动化上传恶意跳转钓鱼页面文件
    3. 获取钓鱼后的用户隐私进行黑产交易

     

    三、网站被挂钓鱼的现象

     

    恶意跳转钓鱼页面文件名为：

    1. _sys.asp
    2. pro.asp
    3. dawn.asp
    4. bas.asp

     

    当我们试图单独访问这些文件的时候，页面只会返回一个数字0，如图：

    而钓鱼者可生成链接如：http://luyuanwine.com/_sys.asp?&jcv.ix&s&

    访问如上链接将会自动跳转到钓鱼页面，_sys.asp?后面则是黑客生成的伪随机字符串，他们将利用被入侵的网站进行页面跳转到钓鱼网站，实施钓鱼攻击。

     

    被入侵后上传钓鱼页面的网站将会被安全联盟等检测到恶意页面存在，导致搜索引擎降权、浏览网页弹出安全拦截提醒等情况发生。

     

     

    四、钓鱼跳转现象的背后细节

     

    我们前面说过，第二天访问被挂跳转页面的网站链接时，跳转后的链接变了，着实令我们感到奇怪。我们来看一下之前保存下来的两个跳转后的链接：

    1. http://zohqdt.eicp.net:2/27/
    2. http://qkepisav.vicp.cc:2/27/

     

    我们发现钓鱼团伙果然心计多端，采用的是免费二级域名提供商，钓鱼团伙利用免费域名提供商提供的服务域名来进行跳转，采用二级域名的好处有非常大的一点原因就是大大增加后期调查难度。

     

    我们获取了恶意跳转文件的样本，发现_sys, dawn, pro, bas.asp源代码均相同，仅仅是名字不同，恶意跳转文件样本很有趣，加花又加密：

     

    整个跳转钓鱼页面的ASP源代码

    [1: http://blog.knownsec.com/wp-content/uploads/2014/01/Phishing_source_encode.txt]

     

    他们对代码变量全部进行了打散加花来迷惑站长或者文件分析者。

    经过漫长的解密，我们得到了原本的文件源代码：

    [2: http://blog.knownsec.com/wp-content/uploads/2014/01/Phishing_source_decode.txt]

     

    这个源代码文件实现了：

    1. 判断SQL注入攻击
    2. 判断通道（http://mayeav.com:2/xx.txt）是否正常
    3. 获取通道内URL地址进行跳转
    4. Title进行随机生成

     

    他为什么会跳转动态的域名这一疑问现在就比较好解答了，其中来看代码46行：

    Response.Write “http://” &Request.ServerVariables(“HTTP_HOST”)&”  [通道正常 ” &EE__E_(“http://mayeav.com:2/xx.txt”)&”]”)

     

    代码会判断http://mayeav.com:2/xx.txt通道连接是否正常，然后58行代码会read xx.txt内容读取后进行跳转请求，整个过程可谓跳转连连。

     

    网站跳转–>获取通道内URL连接–>跳转二级域名钓鱼网站–>真实域名

     

    五、侦查钓鱼源头

    正如大家所望，是时候侦查一下钓鱼的源头了：）

    首先我们从分析样本阶段获取了最有意义的钓鱼攻击者真实域名：http://mayeav.com:2/

     

    于是理所当然的获取到了后台路径：

    钓鱼网站管理中心后台标注： 【V 2013】马爷工作室后台系统

     

    mayeav.com:2/01/

    mayeav.com:2/02/

    mayeav.com:2/…/

    mayeav.com:2/29/

     

    目录01穷举到29均是各种钓鱼网站，钓鱼网站目录：

     

    /admin/# 管理员后台

    /images/# Pic

    /Images/jdmk/

    /27/index_files/ff45cc10.jpg

    /27/include/

    /20/vget_i.js

     

    通过mayeav.com的注册人信息，我们得到了马爷的QQ号码：1872395818

    同样经过域名反查还得到了很多私服域名，且全部跳转到马爷钓鱼站点，所以这里推测私服域名注册人与马爷相识或者就是同一人所为。

    过了一杯茶的功夫，我们通过私服域名获取了如下的一份资料：

    联系人： 小往

    联系电话： 13618***453

    归属地： 湖北武汉

    电子邮件： 48**62@qq.com

     

    我们将拥有的以上资料的人假定为钓鱼团伙成员[A]，紧接着我们又得到了一份关于钓鱼团伙成员[A]的朋友QQ号码，通过查询48**62时发现一个帖子中附带某网址链接，同样私服域名中也有他的注册（成员[B]）。

     

    让我们来看看整个名单：

    马爷 QQ: 1872395818

    团伙成员[A] QQ: 48**62

    团伙成员[B] QQ: 505***850

     

    我们通过伪造身份接触钓鱼团伙成员[A]，从长期深入聊天对话得知，成员[B]、马爷确实与他相识，这里基本可以拟定三人全部都是整个钓鱼团伙的谋事者：

     

    最后我们要去后台里面看个究竟了，看看这个钓鱼团伙究竟有多庞大？

     

    我们可以看到后台管理里面分为邮箱模板和空间模板，而每个钓鱼页面都是单独的一个模块，攻击者经过简单的配置即可发送给网民进行钓鱼攻击，从后台规模来看他们盗取的QQ号码以及其他网民信息已经过万条信息级别。

     

    在此忠告所有网民：“登陆网站时应先仔细确认网址是否为正常网址，以免发生不必要的损失！”
