Introduction<\/strong><\/h4>\n\n\n\n

PowerShell is known for its incredible versatility, but some of its best features remain hidden from everyday users. One such obscure yet highly useful trick<\/strong> is Clipboard Tunneling<\/strong>\u2014a technique that enables data transfer between local and remote machines using the clipboard<\/strong>.<\/p>\n\n\n\n

This method eliminates the need for file transfers, network shares, or manual copy-pasting, making it a game-changer for sysadmins, developers, and security professionals<\/strong>. Let\u2019s explore how it works and why it\u2019s a must-know technique.<\/p>\n\n\n\n

What is Clipboard Tunneling in PowerShell?<\/strong><\/h2>\n\n\n\n

Clipboard Tunneling uses two simple PowerShell cmdlets:<\/p>\n\n\n\n

    \n
  1. Set-Clipboard<\/code><\/strong> \u2192 Copies data into the clipboard.<\/li>\n\n\n\n
  2. Get-Clipboard<\/code><\/strong> \u2192 Retrieves data from the clipboard.<\/li>\n<\/ol>\n\n\n\n

    By leveraging these commands within PowerShell remoting (Invoke-Command<\/code>)<\/strong>, we can transfer data across machines without the need for intermediate files<\/strong>.<\/p>\n\n\n\n
