How do you bruteforce a windows mapped network drive on lan? I know half of the password already and have created a wordlist with crunch. I am not sure how to bruteforce it using hydra or any other script available on kali linux. My question is how do i direct hydra to the mapped drive, for ex //192.168.2.9
You need to attack the SMB protocol with your brute username / password lists.
Remember that if you're attacking a network user you'll want to account for the domain in the username, and bear in mind that dictionary attacks are very noisy.
