Participants have only the IP address of Machine 1 initially. No credentials are provided—everything must be discovered.

This extracts a hex data stream that, when saved as data.bin , reveals a ZIP archive containing pcap_chal.pcap .

The CCT2019 room on TryHackMe is a multi-part challenge designed to test your ability to investigate network traffic. It is primarily centered around analyzing .pcap files—packet capture files that hold the "DNA" of network interactions 1.2.1. Intermediate

Summary

The first task begins with a file named . Initial analysis shows it contains USB traffic.

The goal is to identify a specific, hidden piece of information within the network traffic.

: While human intuition assumes a statistical starting position of index 1 , the processing code must be designed using zero-based indexing ( 0 ). tryhackme cct2019

Alternatively, we can also use the SQL injection vulnerability on the web application to inject malicious SQL code and extract sensitive data, such as user credentials.

To complete the CCT2019 challenge, participants will need to have a good understanding of the following skills and knowledge:

This public link is valid for 7 days and shares a thread, including any personal information you added. This link or copies made by others cannot be deleted. If you share with third parties, their policies apply. Can’t copy the link right now. Try again later. Participants have only the IP address of Machine 1 initially

: Ensure every step is backed by evidence found within the provided files.

The ultimate phase moves away from data transit and focuses directly on software reverse engineering. Compiling and Executing:

If successful, list all hidden files ( ls -la ). Look for configuration files, backup scripts, or text notes containing usernames or passwords. 2. Web Application Directory Busting The CCT2019 room on TryHackMe is a multi-part

This room often features a vulnerability where you can manipulate URL parameters to read internal system files like /etc/passwd .

With the decrypted file in hand, you now have a Windows executable. This is the famous re3 reversing challenge. Running it presents a GUI with four sliders. The goal is to find the exact combination of values that satisfy the program's hidden logic.
