This is a very simple script. It allows us to check whether a proxy service we found on a port is an open proxy. If a proxy service is an open proxy, we can use the server as a proxy to perform different attacks and to avoid detection, especially during a red team activity.

2. Clicking on the module name, we will be redirected to the options where we set the IP, the port, and the URL to check the proxy settings.
3. Clicking on Run Module will create a new task:

If the proxy is open, we will see a message in the task window, as shown in the following screenshot:

Now that we have a better understanding of performing active reconnaissance using Metasploit, let's move on to the next topic to learn about passive reconnaissance.
