msf exploit(vsftpd_234_backdoor) > show targets
...targets...
msf exploit(vsftpd_234_backdoor) > set TARGET < target-id >

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
