The room on TryHackMe is a multi-task CTF designed for the U.S. Navy Cyber Competition Team 2019, focusing on networking, reverse engineering, forensics, and cryptography. 1. Task 1: pcap1 (PCAP Analysis) Goal: Analyze a network traffic capture file.
Set up a netcat listener on port 6667 (default IRC port):
The second task presents you with code written in .NET. By analyzing the code, you'll identify an IF statement whose solution unlocks the flag. cct2019 tryhackme
If the system kernel is outdated (e.g., Ubuntu 18.04), known exploits like dirtycow or CVE-2021-3156 (sudo buffer overflow) might work. Always check uname -r .

Use tools like Chisel , Socat , or SSH port forwarding to route your traffic through the compromised machine into the internal network.
Unlike beginner-friendly tracks, CCT2019 presents an that targets multi-disciplinary security engineers. The environment intentionally shifts between blue-team network forensics and red-team binary analysis. The Pitfalls of Red Herrings Task 1: pcap1 (PCAP Analysis) Goal: Analyze a
This is a marathon, not a sprint. The challenge is designed to be painstaking.
Using Nmap, we can scan the target system's IP address and identify the open ports and services:
Opening pcap2.pcapng in Wireshark, you'll notice that the traffic contains USB packets—specifically URB_BULK out (from host to USB device) and URB_BULK in (from USB device to host). The traffic pattern is highly regular, suggesting some kind of automated file transfer is occurring.
