RDP Port Knocking

This program implements port knocking for access to Windows via RDP / TS.

Warning

Make local tests before using this software, as it was tested only on Windows 7 and Windows Server 2012. Use it your own risk, we are not responsible if you completely lose your access to the operating system.

First steps

It is important to note that firewall settings and remote access service installation must be done in advance by a qualified professional.

How it works

The application will listen to 3 random ports (which you can modify later) and allow TS / RDP access to your Windows environment. After 30 seconds access will be blocked, not affecting the current session (if any).

The user has 30 seconds to make the connection (using some TCP socket client - like telnet), in the proper sequence of ports (1, 2 and 3).
