The second packet capture records raw USB device communications. Standard HTTP or TCP stream assembly will not work here.
As hinted in the challenge description, "If you're doing stego or re, you're either down a rabbit hole or there's an easier way". The key is focusing on pcap-related skills.
Success in this task depends entirely on correctly recovering the first file in its entirety. Failing to do so often leads to broken dependencies in later steps.
CCT2019 on TryHackMe is an "Insane" difficulty, legacy room based on the 2019 U.S. Navy Cyber Competition Team assessment. It focuses on rigorous forensic analysis, requiring accurate traffic reconstruction and deep binary analysis rather than simple flag hunting. For a detailed breakdown of specific challenges, see GitHub jesusgavancho/TryHackMe_and_HackTheBox. CCT2019 TryHackMe Challenge: Analytical Depth Over Speed
The journey begins with intense PCAP analysis , where you act as a digital detective sifting through network traffic to identify suspicious activity and exfiltrated data. tryhackme cct2019
Inside fakeflag.txt is a message from Morpheus (The Matrix) with a password: Z10N**** .
Here are some tips and tricks that can help participants complete the CCT2019 challenge:
The room on TryHackMe (still playable today) isn’t just a holiday gimmick. It simulates a realistic kill chain: External recon → Web app weakness → Shell upload → Low-priv access → Cron job abuse → Root compromise → Ransomware deployment
Q: How do I access the challenge? A: Participants can access the challenge by connecting to the TryHackMe VPN and accessing the CCT2019 challenge network. The second packet capture records raw USB device
The file contains thousands of packets designed as intentional red herrings. Analysts must use advanced Wireshark or tshark display filters to isolate anomalous protocols. Focus on streams handling file transfers or interactive command sessions.
If a directory looks empty, try different file extensions (.php, .bak, .txt).
Once the surface area is mapped, you look for vulnerabilities in the web application.

The cryptography portion of CCT2019 is a multi-stage puzzle. You will receive a ZIP file containing a series of increasingly difficult ciphertexts.

The room is divided into several tasks, each focusing on a different aspect of cybersecurity.
