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

: 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:

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 tryhackme cct2019

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:

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

is a collection of "Insane" difficulty legacy challenges originally designed for the US Navy Cyber Competition Team 2019 Assessment

. It is not a standard linear room but rather a set of high-level assessments spanning various domains including Forensics, Reverse Engineering (RE), and Network Analysis. Key Challenge Breakdowns

Based on community solutions, the room focuses heavily on analytical depth rather than rapid exploitation. 1. Forensic Challenge (Wireshark PCAP)

This task is often cited as one of the hardest Wireshark challenges on the platform. Objective: Analyze a complex file to identify malicious activity or extract hidden data. Key Techniques:

Identifying non-standard protocols or data exfiltration over common ports (e.g., DNS or ICMP).

Carving files from traffic streams (e.g., extracting transferred binaries or documents). Following TCP/UDP streams to reconstruct session data. 2. RE3 (Reverse Engineering)

A .NET-based reversing challenge that requires bypassing a high-security "slider" mechanism. is the primary tool used to decompile and analyze the application. Solution Logic:

Decompile the binary to find the logic governing the "sliders." room on TryHackMe, originally from the US Navy

Identify a mathematical condition (factorization) that must be met for the key to generate.

The goal is to find factors of a specific large number (e.g., 711,000,000) that are below a certain threshold.

Once the factors are found and sliders are set in descending order, the application reveals the flag. 3. General Assessment Structure

Structured assessment designed to test reasoning under pressure rather than a simple "grab-the-flag" exercise. Time Limit:

Historically listed with a 180-minute window for the assessment. Recommended Tools

For these "Insane" level tasks, ensure you are proficient with: Forensics: Wireshark, NetworkMiner, binwalk, and Tshark. Reverse Engineering:

dnSpy (for .NET), IDA Pro/Ghidra (for native binaries), and GDB. You can find the official room to start the machines at TryHackMe - CCT2019 specific challenge

Cracking CCT2019: A Deep Dive into Analytical Cyber Challenges

If you are looking for a TryHackMe room that moves beyond basic "grab-the-flag" mechanics, CCT2019 is it. Originally designed for the U.S. Navy Cyber Competition Team 2019 Assessment (sponsored by the U.S. TENTH Fleet), this room is now available for the community to test their mettle.

Ranked as Insane in difficulty, this isn't just about speed; it’s a structured assessment of your ability to analyze, verify, and reason under intense pressure. Why CCT2019 is Different

Most CTFs reward the fastest exploit. CCT2019, however, prioritizes analytical depth. To succeed here, you need to adopt a "Zero Trust" mindset where nothing is taken at face value.

PCAP Analysis: This is a heavy focus. You'll encounter misleading "red herrings" designed to pull you down rabbit holes.

Traffic Reconstruction: You aren't just looking at packets; you are recovering entire payloads from raw captures. Key Lessons from CCT2019

Reverse Engineering: You’ll need to dig into .NET applications and binaries using tools like dnSpy to understand execution logic.

Layered Cryptography: Each step depends on the previous one. If you fail to recover a file correctly at the start, you may find the later stages impossible to solve. Key Tasks & Walkthrough Highlights

The room is divided into several grueling tasks that test diverse skill sets:

USB Traffic & PCAPng Analysis: In the initial stages, you might encounter USB packages within a pcap2.pcapng file. Analysts often use binwalk to find nested compressed files like pcap_chal.pcapng or tshark to extract contents exchanged via USB.

Reverse Engineering (re3): One specific challenge involves a .NET application. Instead of looking for a simple flag string, you may need to decompile the assembly with dnSpy and solve mathematical puzzles—like finding factors of a specific number to determine slider values in a GUI—to reveal a 32-character hex blob.

Advanced Cryptography & OSINT: Later tasks involve complex decryption methods. You might find yourself using sites like Cryptii to work with Enigma M4 "Shark" ciphers or performing OSINT on YouTube to find passwords for Railfence-encrypted files.

Custom Scripting: The final steps often require writing custom Python code to convert number sequences into binary and then into ASCII to reveal the final flag. Expert Advice for Success

Experienced players on platforms like LinkedIn and Medium emphasize one thing: don't rush.

Validate Everything: Every artifact must be tied back to evidence. If a clue seems too easy, it might be one of the room's many red herrings.

Master Wireshark: This is "one of the hardest Wireshark pcap CTFs" out there. Make sure your packet analysis skills are sharp before diving in.

Focus on the First Step: Recovering the first file in its entirety is critical. Mistakes here will haunt you in later tasks.

CCT2019 is a masterclass in modern digital forensics and incident response (DFIR). If you’re ready to move past the basics and see how the professionals are assessed, head over to the TryHackMe CCT2019 Room and start your investigation. CCT2019 TryHackMe Challenge: Analytical Depth Over Speed


Key Lessons from CCT2019

  1. Default credentials are deadly – The elf account used a weak password, leading to full compromise.
  2. File upload features need strict filtering – The web shell was uploaded because only a MIME type check was in place.
  3. Cron jobs must be immutable – A world-writable script run as root is a privilege escalation goldmine.
  4. Defense in depth – Even after gaining a low-priv shell, the attacker could move laterally because of poor filesystem permissions.
