Hello,
If you want to obfuscate Powershell code you can encode it and use it with the -EncodedCommand argument to the Powershell.exe command.
# Encode a command : Text -> Bytes -> Base64# Command definition$commands = '1..5 | Foreach-Object -Process { "Vive Moi!" }'# Text -> Bytes$bytes = [System.Text.Encoding]::Unicode.GetBytes($commands)# Bytes -> Base64$encodedString = [Convert]::ToBase64String($bytes)# Display the encoded value$encodedString
# Copy the value to the clipboard$encodedString | Set-Clipboard
# Use the encoded command (in unicode) in PowershellPowerShell -EncodedCommand MQAuAC4ANQAgAHwAIABGAG8AcgBlAGEAYwBoAC0ATwBiAGoAZQBjAHQAIAtAFAAcgBvAGMAZQBzAHMAIAB7ACAAIgBWAGkAdgBlACAATQBvAGkAIQAiACAAfQA=
