File download and upload operations using FTP

FTP Downloads
Another way to transfer files is using FTP (File Transfer Protocol), which use port TCP/21 and TCP/20. We can use the FTP client or PowerShell Net.WebClient to download files from an FTP server.

We can configure an FTP Server in our attack host using Python3 pyftpdlib module. It can be installed with the following command:
Installing the FTP Server Python3 Module - pyftpdlib
$ sudo pip3 install pyftpdlib
Then we can specify port number 21 because, by default, pyftpdlib uses port 2121. Anonymous authentication is enabled by default if we don't set a user and password.
$ sudo python3 -m pyftpdlib --port 21
After the FTP server is set up, we can perform file transfers using the pre-installed FTP client from Windows or PowerShell Net.WebClient.
When we get a shell on a remote machine, we may not have an interactive shell. If that's the case, we can create an FTP command file to download a file. First, we need to create a file containing the commands we want to execute and then use the FTP client to use that file to download that file.
