What software can be used to select a password?

Question

Information Security

In our company, on some sites, a form is used where the password is 4 digits. I want to show that this is not the best option, I need a program that can pick up these numbers. Tried Hydra but it can't pick up the password!
Password: 3784

Answer 1

+ captcha + input limit

Answer 2

Those. you want to constantly change the password later because long employees always forget))

Answer 3

Install Kalilinux, it has Metasploit bruteforce, and then what? google in this direction, there is even a video somewhere.

Answer 4

Captcha, limits, IPs, the main thing is the tail! A person has pain for safety, because it is clear that there is nothing there. ;)
