Cct2019: Tryhackme |work|

In this article, I will provide a comprehensive walkthrough of the CCT2019 room. We'll cover what makes this challenge so unique, break down each of its four main tasks, and walk through the analytical processes required to capture every flag. Whether you're a seasoned security professional looking to sharpen your skills or an ambitious beginner ready for a challenge, this guide will help you navigate one of TryHackMe's most rewarding rooms.

(ALL) NOPASSWD: /usr/bin/python3 /opt/script.py

Every successful engagement begins with thorough information gathering. Your initial target is the public-facing gateway machine. Nmap Enumeration

: Carving and recovering files natively from raw packet streams.

The /opt/backup.py script contains a system backup routine. However, because we have write access to the directory, we can modify the script. When chester executes it via sudo , our malicious code runs as root. In this article, I will provide a comprehensive

Use Wireshark or tcpdump to inspect the provided .pcap file.

This article provides a detailed, step-by-step walkthrough to compromise the target machine and capture both the user and root flags. Phase 1: Information Gathering and Enumeration

: Sort the capture by protocol type (looking for non-standard data encapsulation or administrative channels). (ALL) NOPASSWD: /usr/bin/python3 /opt/script

You will need to examine how a binary executes, specifically looking at conditions that govern loops and functions.

Every great hack starts with reconnaissance. For this room, we begin with an nmap scan to identify open ports and running services.
