PowerShell Clipboard Data Transfer

Invoke-Transfer

Invoke-Transfer is a PowerShell Clipboard Data Transfer.

This tool helps you to send files in highly restricted environments such as Citrix, RDP, VNC, Guacamole.. using the clipboard function.

As long as you can send text through the clipboard, you can send files in text format, in small Base64 encoded chunks. Additionally, you can transfer files from a screenshot, using the native OCR function of Microsoft Windows.

Requirements

• Powershell 5.1
• Windows 10 or greater
