Welcome to my writeup! We will explore Agent Sudo room in this writeup!

Task 1

Deploy the machine and ready to dive in!

Task 2

Lets perform a nmap scan on target system

┌─[woahuh@parrot]─[~]
└──╼ $nmap -sV -Pn -A 10.48.164.152

Nmap scan report for 10.48.164.152

Now we got some basic information and we see 3 ports are open

Welcome to my first writeup! Today we will solve the Brute It CTF in Try Hack Me!

First, lets go find some information on target’s system with a nmap scan

┌─[✗]─[woahuh@parrot]─[~]
└──╼ $nmap -sV -Pn -A 10.48.188.61

And then, we got this output

Starting Nmap 7.95 ( https://nmap.org ) at 2026-02-01 06:19 +07

As the output, we have 2 ports open, and thats the answer of question 1
