Lab Scoreboard

Lab Walkthrough Video:

A Ubuntu machine and a Windows machine (Server 2019) are provided to you

The target Windows machine is configured with Firewall turned on and the Outbound port range 4444-6009 is blocked. Your task is to use Metasploit reverse_tcp_allports payload to knock all the TCP ports to receive a reverse shell connection.

Note: You can start the Metasploit framework using the 'msfconsole' command and to generate malicious executables use the 'msfvenom' command.


  • You can check the IP address of the target machine by running "ipconfig" command on the command prompt i.e cmd.exe
  • Do not attack the gateway located at IP address

The following activities are strictly prohibited on this website unless otherwise explicitly stated as allowed in the mission statement:

  • Using automated scanners
  • Using brute force attacks
  • Denial of Service attacks
  • Attacking other student machines in challenges where you might achieve a shell on the vulnerable system
  • Attacking the lab infrastructure

Users violating the above will be either temporarily or permanently banned from the website. 

If you are unsure about an activity, then please contact support to confirm that it is allowed on our website.

Technical Support for this Lab:

There is a reason we provide unlimited lab time: you can take as much time as you need to solve a lab. However, we realize that sometimes hints might be necessary to keep you motivated!

We currently provide technical support limited to:

  • Giving hints for a lab exercise
  • In rare circumstances, if you have totally given up (NO!!!) then tell you how to solve it. This will be limited to sharing the solution video or lab report
  • A lab exercise fails to load or has errors in it

If you need technical support, please email  clearly mention the name and link of the lab exercise and other essential details. The more descriptive you are, the faster we can help you. We will get back to you within 24 hours or less.
