Task 3: Enumerating SMB

From this task on is where the fun starts! First, let’s setup the env var to make the following commands easier.

export ip=10.10.0.0 # change it to your target machine's ip

Conduct an nmap scan of your choosing, How many ports are open?

Let’s run an nmap scan. As a reminder, these are what the flags mean:

• -sV: service/version scan
• --script vuln: run a script scan with the vuln scripts.
• -oN nmap-$ip.out: output in normal format to the file

nmap -sV --script vuln -oN nmap-$ip.out $ip

Now to check for open ports from the scan results.

cat nmap-$ip.out | grep open
