Tryhackme Cct2019 May 2026

room on TryHackMe, originally from the US Navy Cyber Competition Team, is less of a linear story and more of a gritty, disconnected puzzle set. However, when you piece the forensic and reversing challenges together, a narrative of

espionage, digital smuggling, and high-stakes cinematic references The "Put Together" Story

The narrative arc of CCT2019 feels like a modern techno-thriller where you play an investigator tracking a cell of sophisticated hackers: The Digital Handshake

: The story begins with a suspicious traffic capture. An unknown group has been passing sensitive files over an unconventional port—specifically The Cinematic Cipher

: You discover the files aren't just encrypted; they are wrapped in

. In a nod to 90s hacker culture, the "password" protecting this digital contraband is BER5348833

—the same identification used by Angela Bennett in the classic film The Hidden Payload tryhackme cct2019

: Once you break the encryption, the story moves into the "RE" (Reverse Engineering) phase. You are no longer just looking at traffic; you are dissecting the custom tools the hackers left behind to understand their next move. Room Context : Created by the US Navy Cyber Competition Team and sponsored by the US TENTH Fleet Difficulty : Rated as

, reflecting the high-level forensic skills required to "put together" the clues. Core Skills : You will need to master PCAP analysis Cryptcat decryption Assembly-level reversing to finish the tale. or a guide to the RE3 reversing challenge? CCT2019 - TryHackMe

is a "legacy" collection of challenges originally built for the U.S. Navy Cyber Competition Team 2019 assessment. It is rated as

difficulty and is designed to test deep analytical reasoning rather than quick exploitation speed. Challenge Breakdown

The room is structured as a series of assessment tasks rather than a typical "grab-the-flag" box. Key focus areas include: Network Forensics (PCAP Analysis):

Requires deep inspection of packet captures to identify traffic reconstruction and recover payloads from raw captures. Reverse Engineering: room on TryHackMe, originally from the US Navy

You must reverse engineer binaries to understand execution logic instead of just searching for simple strings. Cryptography:

Includes layered crypto challenges where each step depends on the correct interpretation of previous findings. For example, one known solution for the

task involves concatenating a keyboard layout name three times in lowercase. Digital Forensics:

The challenges often include misleading paths and "rabbit holes" to test your ability to validate evidence under pressure. Key Tips for Completion Zero Trust Mindset:

Treat every artifact as potentially misleading. Validate every piece of evidence before proceeding to the next step. Time Management: The room has a suggested duration of 180 minutes

, but its complexity often requires more time for thorough analysis. Community Resources: The /admin directory contains a login panel

If you get stuck, there are walkthroughs available on platforms like for specific tasks such as specific task

Phase 3: Initial Foothold Attempt

The MySQL password does not directly grant SSH access. However, revisiting the web server with further enumeration reveals another hidden directory: /admin.

The /admin directory contains a login panel.
Testing the leaked MySQL password (S@k3n4cc3ss_My5q1) on the login form fails.
Brute-forcing the /admin login using default credentials (admin:admin) or SQLi is unsuccessful.

1. Challenge Overview

The CCT2019 is structured as a narrative-driven challenge. Unlike standard "boot-to-root" machines, this event was divided into specific "Tasks," each acting as a standalone puzzle. The difficulty curve ranges from beginner-friendly logic puzzles to intermediate technical challenges.

Key Skills Tested:

OSINT: Finding information from public sources.
Cryptography: Decoding ciphers (Base64, Binary, Caesar).
Steganography: Hiding data within images or files.
Web Exploitation: Enumerating web directories and inspecting source code.
Forensics: Analyzing PCAP files and memory dumps.

What You Learn After Completing TryHackMe CCT2019

Finishing this room isn't just about bragging rights. It concretely teaches:

Defensive Mindset: If you were the sysadmin, you'd realize: never put an admin console on port 80; never allow raw command input; never set SUID on binaries like find.
Linux Internals: You'll deeply understand process permissions, environment variables ($PATH), and the danger of relative paths.
Web App Security: You'll recognize that "ping" or "traceroute" tools in web apps are disaster zones if not sanitized.
