TryHackMe: Psycho Break

This is the my first time joining the hacking game. To be honest, it quite fun actually and learn a lot from this game even though it takes 16 hours to complete. LOL

Level: Easy

So, lets get started

Recon

First need to find how many port open by targeted machine

# nmap 10.10.X.X
Starting Nmap 7.91 ( https://nmap.org ) at 2021-02-27 09:18 +08
Nmap scan report for 10.10.X.X
Host is up (0.21s latency).
Not shown: 997 closed ports
PORT   STATE SERVICE
21/tcp open  ftp
22/tcp open  ssh
80/tcp open  http
Nmap done: 1 IP address (1 host up) scanned in 29.40 seconds

Now, which OS the target machine is running? lets find out

# nmap -A -Pn -T4 10.10.X.X
Host discovery disabled (-Pn). All addresses will be marked 'up' and scan times will be slower.
