139/445 - SMB

What all I do, when I see 139/445 Open:

1. Find SMB Version: tcpdump -i tun0 port <Victim Port> and src <Victim IP> -s0 -A -n 2>/dev/null & crackmapexec smb <Victim IP> --shares --port <Victim Port> 1>/dev/null 2>/dev/null

2. Nmap Scan: nmap --script "safe or smb-enum-*" -p 445 <IP>

3. Shares: smbclient -L \\\\<IP>\\

4. Changing Shares: smbclient -L \\\\<IP>\\C$

5. Lists file with permissions: smbmap -H <IP>

6. Downloading: smbget -R smb://<IP>/anonymous

7. type prompt off, recurse on -> lets us download all the files using mget *

8. Nmap Vuln Script: nmap --script "smb-vuln*" -p 139,445 <IP>
