I am using Kali Linux as an attacker machine for solving this CTF. Let us try to decrypt the string by using an online decryption tool. Deathnote is an easy machine from vulnhub and is based on the anime "Deathnote". It tells Nmap to conduct the scan on all the 65535 ports on the target machine. In the next step, we will be using automated tools for this very purpose. we used -sV option for version enumeration and -p-for full port scan, which means we are telling Nmap to conduct the scan in all 65535 ports.
